My bobcat is unable to wweld what my b the cause
Remove the side doors, and top cover, make sure your brushes are making correct contact against the slip rings, there is a flat mounting panel behind the range control switch, you will see 2 white fuses in their holders, check these fuses, one controls AC output the other controls weld current output.

If the idle is not working, then it is either you idle solenoid attached to the carberator or your idle board is bad. If you apply 12Vdc to the idle solenoid is should move, if not then the solenoid is shot, no good. If it works then you idle board is bad. Also, check to see if you are 60Hertz by measuring at the outlet with a frequency meter. I recommend a Fluke meter. You should have 120Vac and 60HZ at the outlet. If the frequency is low then your engine speed needs to be increased. The idle solenoid could be causing all these problems.

Make sure that the idle is set at 40Hz. You do this by placing a frequncy meter on one of the 120Vac outlets. If frequency is low, the engine will run rough at idle. There is a 3/8 nut next to carberator that needs to be turned to the right to increase the idle speed.

SOURCE: miller welder bobcat 225 won't weld, terminal
Check the terminal connections. How old is it, brushes on that thing are pretty fragile
SOURCE: trying find out what i
you will need a AC high frequency unit to weld aluminum. For stainless and mild steel just need a dry run tig torch, hose kit and 100% argon.
