Miller welder 44 G wont weld has power to outlets

Well it can be a number of things. If you are not a certified tech, I would recommend taking your machine to a authorized service center. If you feel comfortable checking the brushes, that is what I would check first. Other than that, it could be rheostat, R2, SR2, or generator windings. I am including the owners manual. https://www.millerwelds.com/files/owners-manuals/O458M_MIL.pdf

Miller Bobcat(Gas)machine AC output to aux. power receptacles, does not meet required voltage. Only 70% required voltage 120 and 240.

On a Bobcat, the big knob needs to be turned all the way up to 10. If it is, then the engine speed (RPM) might be too slow at fast speed.

I have a miller bobcat 225 is lower power while welding, any idea?

First off, check all of your welding cables to make sure they're in good shape, then check for tight cable connections. Is your machine staying at low idle speed while trying to weld? If so, Switch the idle select into the 'weld' position and make sure the high RPM's initiate. Try welding again. Better? Could be a number of things, if not.

I have a Miller Big Blue 251D and while welding it died and won't restart.

Hi:
Have you check the fuses? Probably your machine experienced an overload. Check your owners manual on the troubleshoot section. Here's the link to the manual.

Miller bobcat 225g plus welding problem

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.

open inspection door,which also the fine tuner knob is ,there's a 2x4 size circut board that snaps out with little force to remove,this is the voltage regulator board,look for 4700 ohm resisitor burnt into,tv tech can fix or order new board at $227.00 what i paid.
