Hii all, i,m looking for a pcb for a newarc r4500mp. The one behind the front panel with the current meter, switches ect connected to it. Was wondering if someone might know where i might find a used one or a welder i could buy for spare parts. Or even a good welder and i could use mine for spares. Was going to buy a new welder when this one laydown on me but in the current climate (covit19 ect) i'm going to fix my old unit. Any help would be appreciated.
