I hope someone can help. I picked up a used Millermatic 250 that was supposed to be in working condition. The M25 gun was a bit ugly with tape on the cable and trigger not fully set into the handle and such but within 10min I had it looking much better and hooked it up to the machine. The cable fed nice and easy and the trigger works to feed the wire. The problem that I am having is that the wire will not arc, just sort of spark a bit. If I drag it across the metal with the trigger depressed it will continue to spark like a sparkler but if left in one spot it just does it once and nothing else.
I have read other posts and been checking to see if I have the correct voltage and the usual places (plg1/2, T1, ext..) and it all seems to check out. Also the DCV across the ground clamp and wire align with the voltage the knob is set to.
I pulled the gun apart a bit more last night and there is a white wire that was cut about a foot from the gun end that I cannot find where it would go to. I have been looking at a Bernard Q300 but if that is not the problem I would rather spend the money to make sure the machine gets up and running. Thank you for any help you can provide.
