Colleagues, tell me, I have been suffering with this device for two years already, before it was Telvin 165, but it burned out. I bought FoxWeld, it cooks very poorly with a triple electrode for 110-120 A, the arc disappears at any moment or does not ignite at all, and at 130 it burns metal through. Those. it seems that there is no middle mode. I gave my friend a try, because he sinned on the wiring and crooked hands, he has everything the same, after my Fox with his old trance he welded everything perfectly, he says he was tormented with my apparatus.

Does it make sense to take him for repair? The device really does not cook adequately, compared to Telvin Technica 165.

Serzhio, try to see at least the current regulator. Perhaps the resistor is oxidized or partially fell off. Perhaps this is the trouble.

If not, then for diagnostics and if the price tag stands up to the repair, then ask for a guarantee for three months. And there it will be seen how much it can be in the furnace.

Serzhio 08 Feb 2017

copich, understood thanks! I also needed to understand that there really was a problem. I will carry it to repair.

if the regulation is smooth, then the current should also be smoothly regulated. If there is a step regulation, then the output should also change stepwise, but at the same time increase uniformly. On step adjustments, there is often no change in some steps due to burnt contacts.

Serzhio 08 Feb 2017

Video (click to play).

The fact of the matter is that the adjustment there is smooth, but there is a feeling that from a certain position of the twist, the current strength increases to a maximum, although it shows 130A.

Forget about the display meters on cheap devices. They show how many stars are now above your head or the strength of an ant running past.

This cannot be trusted, it is as a guideline that this is so much closer. In the process of welding, this indicator shows what? Same? It means that he does not measure anything, he only shows.

Resistors (regulators) often suffer. well, turn on the switched off device several times from lock to lock, maybe a little better (for a short time). So the point is in the resistor or with a tester, look at the smoothness of the adjustment. Mandatory on the switched off device. And when you twist, then push a little more and, on the contrary, pull it towards you. And you can also check it, you can pull it off a little, if the matter is in the resistor, there should be 90% deterioration or improvement.

And what about the resistance being checked by the tester on the switched off device?

copich 08 Feb 2017

Yes. If the tester does not automatically determine the resistance, then immediately select either kOhm or mOhm. Depending on what is written on the body.

Igor, i.e. do I need to disconnect the wires from the "twist" and check the change in resistance when it rotates correctly? Or can I not disconnect the wires?

copich 08 Feb 2017

No, you don't need to disconnect anything. Although if on the connector, then of course the purity of the experiment will be higher, i.e. the circuit of the apparatus will not affect the measurements of the resistor. It is enough just with one probe of the tester to the center, with the second probe to the extreme contact and twist. Then to the second extreme contact and twist. If in both positions it changes evenly, then the point is not in the resistor. If there is a ripple, then the matter is in the resistor. Or a drastic change. Although of course there is a chance that bounce is more manifested under voltage, but usually you can catch it with a tester.

If two contacts on the resistor are connected together, then the central and extreme ones are together - one probe, one remaining second probe and take a measurement only once, but do not twist quickly and look at the tester.

Here, of course, a pointer tester is better than a digital one. Chinese digital will be very slow to think. Therefore, only your experience or luck can be counted on.

Well, or just quickly change it to a new one from the store, a resistor. Doesn't help, then figs would be with him

I own devices for several years, cooks with ordinary electrodes is not bad, even on a bad network, but he always had problems with SSSI. Electrode 3 current maximum 200A, wires are thrown over. Does not cook. Here's what happens:
When it is possible to ignite the arc, it cooks for a minute and stops cooking. The fan is running, the display is the same. We are trying to ignite the arc from 3-5 minutes. The arc lit up again cooks for a minute and again does not cook (like chopped off by itself). We try again to set fire to the electrode. Again we poke about 3 minutes. The arc has lit up. We cook, now we burn a quarter of the electrode longer and it stops cooking again. After welding, a crater is formed on the electrode. If a plaster burns out on a conventional electrode, and then metal, then with SSSI the mustache is the other way around.
Tell me why SONI doesn't cook? Is his filling for this brand of electrode not sharpened?
For example, the Chinese resant digests the SSSI like a regular electrode (naturally, we swap the wires).
Help pliz ..

It's not entirely clear about wire manipulation. Do you reverse polarity when welding? From which to which?

So on the electrodes it is written with reverse polarity, if not confusing.
When welding with conventional electrodes + on the electrode, - on the ground.When welding SONI, everything is reversed.

Welding with UONI 13/55 electrodes is carried out with direct current of reverse polarity (+ to the electrode). Resanta cooks them well. it has a higher open-circuit voltage.

when welding with an inverter, i.e. on DC, reverse polarity is required.
for a 3mm electrode, the current is usually 80-120A, depending on the position (floor, wall, ceiling). more precisely, see. on a pack of electrodes.
in your case, with “-” on the electrode, there is not enough heat to melt the coating, as a result of which a visor is formed from the coating and the arc extinguishes.

straight polarity is used when welding with alternating current (transformers).

Thus, the problem is not in the electrode or apparatus, but in the knowledge of the welder.

This is something new about welding.

If for one person, one apparatus cooks, the other does not, then it is obvious that one of the apparatus is not quite suitable for SSSI.

Apparently, this Fox is a typical ZX-7. Not very comfortable, but he should still cook, at least in the lower position.

If you add droselek to the outlet on a spray, then it will cook half a dozen.

ASN, What kind of droselek and where do you need to solder? Droselka brand, parameters?
The members of the forum got confused.
1 inverter -direct current outputs?
2 right polarity whats on the holder +?
3 hand held -?
4 on the electrodes write to cook with alternating or direct current.
5 if it is written on the electrode that it should be cooked with purely alternating current, is it already not suitable for the inverter?

Drosselyok homemade
conditionally permanent
a straight line is “+” on the part “-” on the holder
the inverse is “-” on the part “+” on the holder

if it can be variable, then constant too (inverter)

joha, Thank you. Can you see a photo of this droselka?
It remains to find out why not cook Uonka.

The ring is needed from pulverized iron, 57mm in diameter. It fits between the “+” output of the inverter and the positive terminal.

Already for connection outside the inverter are sold on /don220.ru/

can be done in different ways, can be sprayed, can be alsifer, can be transformer iron

There is no difference, it is possible from the inside and from the outside. When the drawer is large enough, the inside is better.

ASN wrote:

Well, yes, inside, of course, it will be more appropriate.

As I understand it, this apparatus is not intended for uonium welding.
Is this ring only needed for uonium welding, or is the entire welding apparatus being modernized in this way?
Serg52, 57mm outer diameter? Then do you need to wind a certain number of turns of a specific wire on this ring?
Thank you.

All upgrades, the arc will be more stable on all electrodes.
Simply, on the other electrodes, and without a ring, it is cooked more or less, but on uony, without a normal choke, it is completely sad.

At the same time, it should be borne in mind that a global “miracle” will not happen anyway. The problem is, with bridge inverters, the idle U is also not enough (usually 55V), which is unfavorable for the uonya. At the same Resanty Uxx 80c. hence the best stability on the uonya.

Arkady wrote:

Maybe not, but maybe yes. You first try to cook on the correct polarity (+ to the electrode) and write off your impressions. And only then you will wind the chokes.

Arkady wrote:

It is intended, it’s just harder to cook it, but after all, people somehow cook even with devices with WFD, and here the open circuit voltage, although not 80V, but 59V should be enough.Recheck everything again, try to boil in another place, suddenly something with tension, and only then start winding the chokes.

Thanks to the members of the forum. I will try as soon as possible. + on the electrode. Most likely after the holidays. I will definitely write it off.
AHX move already not to raise?

It will be easier to buy another.

See in the topic
FoxWeld Master 162/202 (reviews) On the first page there is a photo of the insides of 202

Arkady, my experience is not gigantic, but I have not come across devices for which somewhere in the characteristics it would be written that they cook with de rutile, but the main ones (to which SSSI belong) are not. IMHO, if the apparatus is capable of producing the CURRENT recommended for these electrodes, then it MUST be cooked with them (if, of course, the apparatus and the network are in good order, the wires and grounding are in order, the electrodes are in proper condition), everything else is a matter of the welder's skills. True, some of the characteristics of the device may nevertheless be associated with some peculiarities, and more on that below.

Maybe your experience in welding specifically SONI is not very rich, and for this type of electrodes you just have some “excessive expectations”? If I was mistaken, then what I have laid out will be useful to someone else, I got here already some kind of small reviewer on SSSI

This is a typical and most widespread representative of electrodes with a basic coating, and they have their own subtleties.

Firstly, they ONLY hold a very short arc, because when it increases, it goes out much more readily than that of the same rutile ones. This is probably due among other things and with a different, than in rutile, dynamics of combustion and melting of the mixture - it melts noticeably more slowly than in rutile. Therefore, the metal usually melts faster than the coating, which therefore forms a “cover”, moving the tip of the electrode shaft further away from the base metal. “Treatment” - boil up to resting the plaster on the base metal at some tilt of the electrode, select the force of this support empirically, depending on the current (for each diameter of the electrode there is a “plug” for the recommended currents), the degree of heating of the base metal, welding position, angle tilt the electrode, etc., while avoiding sticking. Moreover, from batch to batch of electrodes, the results may differ.

Secondly, they have a very difficult repeated (and not only) ignition. This is expressed in the difficult first contact for sparking (obviously due to the greater oxidation of the tip of the rod and its contamination with slags) and in a noticeably greater adhesion. “Treatment” - before reigniting, beat off the edges of this “cover” from the coating, and also remove oxides from the tip of the rod. This can be done, for example, by tapping the tip of the electrode on an auxiliary "piece of iron" or a stone, but do not expose the rod too much - it will stick when ignited. With the advent of some little experience, it turns out to bend the coating faster by knocking the tip directly on the base metal until the first spark (if it is not critical for the surface of the part), after which it is already possible to ignite the arc itself. In a couple of American videos on YouTube, it was suggested as an option to clean the tip of the electrode with a file that you keep close at hand - this is a very specific solution for very “clean” work, but for everyday practice, the method is too troublesome and greatly reduces productivity.

For the subsequent ignition to help the same hot start of the apparatus (whatever the opponents of this idea say - in my practice this is still true

), or find the most suitable ignition method empirically.For my case, with the hot start completely disabled, it turned out to be ignition by a very light striking with a rather large angle of inclination of the electrode - so that after the initial ignition to minimize the pressure on the tip, leading to sticking. After ignition of the arc and its warming up, the required angle of inclination of the electrode is set, and the arc moves to the beginning of the seam.

[In “defense” of these “troublesome” electrodes we can briefly mention the very good spreading of the metal, which gives beautiful and even seams, better visibility of the pool during welding, usually greater strength and ductility of the deposited metal, as well as a thinner and more easily detached slag crust.]

There is a thought that the burning of SSSI really indirectly the open circuit voltage of the device may be affected. With a random increase in the arc, the voltage on it increases, and inverter devices to maintain a given current automatically increase this voltage. But the maximum possible voltage here is nevertheless connected with the Uxx of the inverter (I do not say that it is EQUAL to it, since the Uxx inverter gives only at ZERO current), therefore, inverters with a higher Uxx must keep the arc at more this random increase in the arc (unless, of course, they do not include such functions as, for example, forced arc interruption for the convenience of “tear-off” welding). However, since it concerns deviations from the normal welding mode, this can only give additional "comfort" in work, while observing the NORMAL welding modes and this Uхх affect the actual possibility of welding shouldn't.

Greetings Dear. help me please
My friend bought a Foxweld Master 202 (apparently Chinese). And something burned inside. The circuit in the attached images is (according to him) healthy on the main board. He turned to an electrician for help, but he does not know that it burned out (more precisely, it seems like the resistance does not know what it should be from the factory, and therefore cannot be repaired). Can you determine?

It is impossible to restore the denominations for these remains. We need a photograph of the same block from a living apparatus. Or you can draw a section of the circuit around these elements, try to determine their purpose and guess the nominal value. If your friend can draw a diagram, we can try to help with the denomination.
And one more thing - the resistors themselves do not collapse like that, which means that the main cause of the malfunction is somewhere else (probably on the main board or removed components) and you need to find it by moving along the paths from these burned out resistors. Otherwise, the new ones will make the same boom.

Although, you know - perhaps this board is a complete unit. Optocoupler, Zener diode, transistor. Perhaps this is a zero crossing detector. Can you take a new photo without the flash? The glare hid some of the paths. Bend the green capacitor to the other side, pick the rosin from under the transistor and bend the orange capacitor so that you can see the tracks under them.

If you are looking for a welding machine, and for this purpose have already visited many resources dedicated to professional (and not so) equipment, you probably did not ignore the information about the orange unit with an interesting name Kemppi Master, and the 202 model attracted by the price. What is behind this affordability?

Attractive price, compact design with rounded corners and good parameters look quite “tasty”, but is the thing reliable, do the declared characteristics correspond to reality and does it have a good price-quality ratio? Brand name Kemppi is owned by a Finnish welding equipment manufacturer whose products have been in production since 1949 and have already gained worldwide recognition for quality, safety and energy efficiency.

Image - DIY Foxweld Master 202 Repair

The range of devices is really impressive - from simple inverters for manual welding to robotic systems. One could congratulate the one who stopped buying an orange box with round toggle switches, if not for one little oddity - a Finnish company Kemppi never released an inverter marked Master 202!

Image - DIY Foxweld Master 202 Repair

If the brand is important to you, then it is better to refuse the purchase so as not to become a laughing stock of connoisseurs. In the event that you need a welding machine, the cost of which is two times less than that of a branded one, you can take a risk. At least, the “impostor” with the usual mark “Made in China” has no frankly negative reviews. It performs the main functions at the household level, it is unpretentious in service, and, if you do not dance on it and flatten the horseshoe with a sledgehammer, it may well work for a long period.

Sorry, full description of the welding inverter Master 202 from the company Kemppi with all the desire to find it will not be possible. Unscrupulous sellers “borrow” the parameters of other devices, and in order to understand what this Chinese thing is capable of, we will draw conclusions from practice. Inverter is too loud a name for this unit - rather heavy. The case is strong enough, build to last. There is no fine adjustment of the current level, the adjustment function is performed by a toggle switch marked “weak - powerful”. So the numerical values are a mystery in this case. Image - DIY repair foxweld master 202

To the right of the current parameter switch, on the front panel, there is a switch button, to the left is an overheating control lamp protected by an orange plastic reflector. Unlike Finnish devices, there are no jacks for connecting wires or additional equipment. The wires are short, their length barely overcomes the 1 meter mark. There is no way to replace them or build up, they are connected to the equipment tightly, keeping the secret of the connection inside the case. In general, there is nothing out of the ordinary in the inverter: a simple set of not too "fancy" welding machine.

Welding is also pretty average. The electrode for the inverter marked "2" holds the arc stably, but for the "C" you need to warm up the surface for welding. This is where the lack of power adjustment begins to be felt: even if the button is in the Max position, working with massive profiles is very difficult. The electrodes burn out strongly, the arc sticks. So the manufacturers were cheating by indicating the “fifth” electrode as the maximum on the marking.

Image - DIY repair foxweld master 202

If you are not going to be engaged in welding fittings for skyscrapers, but to carry out minor repairs at the dacha, the capabilities of this "rattler" may be more than enough.

By the way, about the sounds. The welding machine, although rude in appearance, creates a little noise.Internal air cooling works efficiently, even at high load, the heating of the case is minimal, and the temperature control lamp does not respond! In this sense Master 202 behaves perfectly even when working with large profiles - despite the fact that when overloaded the electrodes become very hot, this does not affect the “insides” in any way. The electrode clamp is quite reliable. Another thing is a crocodile located at the end of the wire “to ground”. And although the spring is quite strong, there is a concern that with frequent use, the metal from which it is made will crack pretty soon.

Opinion about Master 202 is rather ambiguous. On the one hand, there is a fairly solid (albeit clumsy) equipment, on the other, something incomprehensible, endowed with the function of an aggregate for the production of welding. By and large, this “something” fulfills its task. This product is suitable for non-professional craftsmen who will use the welding machine from time to time as an assistant for the production of minor repairs in the country or in a private house. It is not suitable for cutting thick metal profiles, but its power is quite enough for joining structures made of ordinary reinforcement. Image - DIY repair foxweld master 202

It is unlikely that now you can find this product in stores that sell branded equipment. Nevertheless, it is quite possible to see advertisements for its sale on the Internet, on numerous forums. There, by the way, the sellers do not hesitate to call the device "Finnish", and also try to give it to amateurs for 14,000 rubles. So be extremely careful! The average cost of this equipment is 6000 rubles, which makes it a rather attractive purchase against the background of the namesakes from the Finnish company, the price of which is two or three times higher.

And one more important detail: when buying the above-described device, be prepared for the fact that there is no talk of providing a guarantee at all. Correctly weigh the pros and cons, once again remembering the principle "we are not rich enough to buy cheap things."
