A welder does not speed up when an arc is struck. It is normal for a gas welder to stay at a high rpm. If it did not, it would be very hard on the machine as a high amperage is needed to start an arc for welding, and to be consistant. Unlike a generator which will "idle down" when not in use.

    i too work with the same machine, bobcat 225g, used primarily for stick welding, at times it, set on run/idle, will idle as it should, but then there are times, when it is set to run/idle that it will idle down, then back up, back down, back up, etc., when it should just idle, for no apparent reason. and it is a gas welder, and no, it is not normal for one set on run/idle to continuously run when not in use, thats the whole point of the run idle setting, to save fuel.

Why does my miller bobcat welder generator not stay at an idle when swithed to low idle, insted it goes back and forth to high then to low idle?


The unit may need recalibrating the idle/run setting. Instructions found in manual at 8-6 (subaru engine) and 9-5 (kohler). Idle speed around 2200rpm. Simple screw adjustment. PDF manual here :- http://www.millerwelds.com/om/o4434l_mil.pdf

Will not strike an arc, but welding machine still runs good


Hi:

Probably your machines overloaded. Check your fuses F1 and F2 and if they are open replace them.
Both fuses are located at left hand side of machine, open it and you will find them on the bracket.

Good Luck.

If this was useful please vote, thanks.

My Lincoln SA 200 welder will not rev up when I strike an arc.


Need code number to be exact, but sounds like the wiring to the current transformer is incorrect.

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.
