Hobart Welding Tools - Recent Questions, Troubleshooting & Support


I am having the same exact problem on an old Hobart Beta Mig 200
sometimes i can weld for 5 minutes and other times as soon as I hit the trigger it trips the 50amp breaker. Any help?

measure ouput on ALL available sockets - anything?
Take cover off electric motor-generator, visually inspect windings.
Measure continuity of all stator windings (2 or 3 points usually)
Measure continuity of stator thru brushset.
If all measures ok - has to be AVR module.

There is no mistery in generator - just stator to induce and rotor to obtain voltage.

Cleanliness is important when it comes to Mig welding. Any rust, dirt, dust, oil is liable to be deposited in the whip liner. If it's just a dirty liner you can try cleaning it with a solvent that doesn't leave an oil deposit (electric motor cleaner, brake cleaner, that sort of thing) compressed air and flexing of the whip.

Make sure your whip hasn't been crimped, if it has then no amount of cleaning will restore it to operation.. a new liner is the only reasonable answer.

It's possible that a bad tip can cause feed issues. Miller type tips are the worst, in my experience, sometimes you just get a tip that will weld to the wire when the current passes between them. I've worked in shops where I might go through three tips in five minutes and then hit one that would last all afternoon. If the wire sticks and you can hold the gun up and rotate your wrist and you feel a 'pop' and the wire jumps out of the tip then just change the tip out. Excessive roller pressure with a tip that's sticking to the wire can really make trouble for you. Nozzle dip is your friend sometimes with tip sticking issues.

Copper clad wire is not particularly friendly to liners, the copper is liable to flake off in the liner. I use bare wire, I bag the wire in a plastic bag on the feeder and I wrap a scratcher pad on the wire just before it goes into the feeder and I find that I have few feed issues. Wire that has even a trace of rust should be discarded as it will both fill your liner with rust and give poor quality welds.

Lots of torches are fairly universal and you are likely to find it cheaper to replace only the parts needed if you can find them - manufacturers tend to prefer to sell the torch (or gun) complete with the hose, cables and sheath and they are expensive though considerable savings can be made dealing with factors or independent supplier/repairers.

Most professional mig welders over here use the euro torch and when a welder doesn't have one and the torch is ready for replacing it is a worthwhile modification, especially if the necessary parts can be sourced secondhand or salvaged.
The euro torch just plugs into the machine and once the machine has been modified there are plenty of usable secondhand ones about that can be had for a song.

If you aren't conversant with the euro torch, try a search...

Is it 220 vts ? If so, Check the outlet with a voltmeter to see if you have 110 vts. On both of the top terminals .

It sounds like a relay is stuck closed. It could be on the control board. Call Miller welding and give them the model number and they will be able to help . Good luck

It’s close enough not to be able to answer that. The inrush current of a welder is huge anyway, so it could exceed the instantaneous capacity of the generator. However, it’s also possible with capacitance in the welder to smooth that out, that it will work fine. The only way to be sure is to test it. If you can’t do that before purchasing, it’s a risk you take. On balance it should work, but may not.

See what your duty cycle is suppose to be for that welder. It may have a internal fan that has stopped working to pull the heat out. Some have some don’t. If not add one and it may give you a little more time to weld

When the generator is not used orstorage for a long time, the residual magnets contained in the iron core are lost before leaving the factory, and the excitation coil cannot establish the proper magnetic field. At this time, the engine is running normally but no electricity is generated. This phenomenon is stored in the new machine and stored in the humid. There are more units in the environment or long-term use.
