I have a millermatic 185. It has been working perfect with no issues till yesterday. I was welding 1/4 thick steel channel when I could not strike an arc. The wire feeds but no arc. I even tried at the ground lug and nothing. I thought maybe a duty cycle.

I have never had it stop before though. I waited till today but still nothing.

All breakers are set and I have full power out of the switch. I thought maybe it was the handset but I get no voltage across the pos and neg lugs in the unit with the trigger pulled. I get wire feed though.

What could I try and what steps might I take to test it out. If diode or diodes are shorted, which is what it sounds like, then replace all of them.If the ally plate where diodes and terminals are mounted are 'pitted' or have been arcing then you will have to reposition them to a flat, clean smooth surface, if you dont they will 'arc' out again, and use a smear of heat sink grease on surfaces when mounting them.You will have to make sure that you get the correct diodes. There are probably 2 types of diodes in your rectifier, wont go into full on technical details but they should have an arrow with a line across, the direction in which the arrow is pointing tells you that the current will flow in that direction, the line across means that current is blocked in that direction.Or better yet some numbers.

Spaceward ho free download. Make sure you install them the same way.Should be able to see picture on here somewhere, do a search.Have a good close look to make sure that you have not missed anything that was supposed to be insulated. Well, I'm sure now that is what I must have done wrong. I did not know they were diodes. In fact I didn't even know there were two different part numbers. I had them all out on the bench and cleaned them then randomly installed them again. Murphy's law tells me they are in there wrong.

Do you know which one goes where? That is the next thing I will have to figure out. I will look at them tomorow to see if there are part numbers on them. Is there a way to test them? Thank you guys for all the help your awesome.
