You'll need to re-structure this into question format and try again, otherwise no one understands what exactly you're trying to figure out.

SOURCE: 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.

250. What causes it to run roughly and lose RPM?


The Miller 212 has a 60% duty cycle. So for every ten minutes of welding the machine is designed to weld for 6 min and cool down for 4 min.

Miller bobcat 250


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.

I have a Miller Syncrowave 250 DX and it has 3 fans, 1 come on as soon as machine comes on and after welding for about 10min the other 2 come on but they are not


Do you mean to say that the other 2 should come on, but are not? Perhaps you are welding using lower settings than before, and the machine just isn't heating up as quickly. Is there a point at which the fans do come on? Say thirty minutes into the job instead of ten? Maybe you were afraid to run it too long without the cooling fans on and so stopped prematurely, before the thermostat turned them on? Check fuses and breakers.

Bobcat 225 runs good but wont weld.Welded great one week prior


Hi:

Probably your machine overloaded. Check the 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. Check your owner's manual for an ilustration of it.

Why is the maintenance light on in my miller 250 bobcat


The maintenance light is probably on because of low oil pressure. Check the level of oil and top it off.

You may also want to check your Air Filter, Fuel Filter, Spark Arrestor, and Fuses.

Here is the manual for your Miller 250 Bobcat:

Probably your machines just overloaded; the engine will run and produce voltage but no weld output.
