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.

SOURCE: No arc on my miller trailblazer pro350

There are two sources of power for the exciter circuit on this machine. The main one takes output power from the generator then goes through the voltage regulator back to the rotating field to continue the cycle of generating. The regulator varies the power back to the rotating field to keep the output steady and correct. The other circuit provides power to the rotating field while you are starting the engine. This starts the loop. It is similar to flashing the fiels on old cars that had generators.
It power from the starting cycle portion seems to be working. This tells me the rotating field, the brushes and the main winding is all good. The problem is most likely the voltage regulator or associated wiring. There are people who repair and return these as they seem to give quite a bit of trouble. If you google the part number of the circuit board, you will probably find a few of these folks happy to repair your board. I have repaired a few myself as it is almost always the same components that fail. Dust,dirt and moisture seem to build up and cause the fault.
I hope this helps. Robert

Miller Legend welder. Onan engine starts and runs a few minutes then dies. Why won't it restart for 5 minutes?


Some engines have a low oil cutoff switch. If the oil level drops to a certain point it kills the engine. Your oil level may be close enough that after starting and running for a little bit the level drops enough to kill the motor. After sitting for awhile the level rises enough to allow the engine to run again check the level and add oil if necessary.
Hope this helps.

My bobcat 225g runs full bore all the time, I thought it would idle then when you strike an arc it would pick up speed,


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.
