Why does my miller bobcat welder generator not stay at an idle when swithed to low idle, insted it goes back and ... Won't strike an arc,fuses ok brushes and slip.

These rigs are notorious for developing bad connections in switches and wiring, as well as getting stuck or burnt brushes in the generator. If it has been sitting for some time, I would definitely do maintenance on the brushes and check switches for rusty or burnt contacts. http://www.millerwelds.com/om/o175104b.pdf

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

Depending on machine model and sn you need to order the fuel gauge repair kit from a distributor. It will have all of the parts needed and instructions on the removal and installation of the new part. This is a commom problem that we are seeing with the Bobcat and Trailblazers. I can drop ship the part from Miller to you if needed. Feel free to contact me at (803) 609-8518 William Scott.

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.

Take off shroud, look at where the positive lead hooks into the transformer. You may find that the wire has melted, If you are lucky, you can loop it tnough to make a fresh connection. (also check the negitive)

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.
