Check your input line voltage. 115 volt Mig welders / plasma cutters need stable voltage / current. Test to see if the voltage drops to below 100 volts when welding. If so, find a more stable power supply.

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.
