Miller syncrowave 200 help
I have a miller syncrowave 200.
The machine was working fine but all of sudden started to melt the tungsten in ac mode.
I sent out the circuit board to get tested and it tested good.
I changed the bottle of argon but still same thing.
I think it’s stuck in dc + while in ac mode.
If anybody on here has any suggestions on what it could be please let me know.
