I have a Hobart 251 mig welder and when I turn it on the wire comes out of the the gun and won't stop till I shut it off ?
If the wire feed on your Hobart 251 MIG welder won't stop when you turn it on, there could be a few possible causes. Here are a few things to check:
- Check the trigger on the MIG gun: Make sure that the trigger on the MIG gun is not stuck or damaged. If the trigger is stuck in the "on" position, it will cause the wire to continuously feed.
- Check the wire feed motor: The wire feed motor could be faulty or jammed, causing the wire to feed continuously. Try disconnecting the wire feed motor from the welder and see if the wire still feeds. If it does not, then the motor is likely the problem.
- Check the wire spool: Make sure that the wire spool is installed correctly and is not jammed or tangled. If the wire is not feeding smoothly from the spool, it could cause the wire to feed continuously.
- Check the wire feed control settings: Ensure that the wire feed control settings are set correctly. If the wire feed speed is set too high, it could cause the wire to feed continuously.
If none of these solutions resolve the issue, it may be best to contact a qualified technician or the manufacturer for further assistance.
My welder is tripping the
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?
I have a Hobart Champion 10,000 welder generator.
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.
Wire feed is sticking when
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.

I need a gun for the Hobart beta mig 170 welding machine
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...
Will a 5.7kva generator run a Hobart 175amp-230v-4.60kv welder
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.
