I have been trying to diagnose a Miller 180sd syncrowave welder I recently acquired. I tried searching all over the Internet and on this site.
The problem is a weak arc, and it's real irratic It won't get hot enough to melt the metal. It was taken to norco and they said they "think" it's the pc board.
I'm a welder and auto mechanic by trade but far from a welder repairman. I can have the board repaired in Florida by gem electronics for 290$ but I want to make sure it's the board. I have tried different leads pedals three phase, 220 all the same. I have had the board out and examined it closely and everything looks good. Ive cleaned and adjusted the spark gaps also. Any help would be great.
