Hi I have an old butters tig/mma machine which has a problem, in tig mode the torch is always live but I can still tig weld with hf start but as soon as I let off the torch button mma seems to come in with massive amps.
if I don't press the button and strike an arc massive amps again which blows the fuse. Im assuming a pcb problem, ive checked the tig/mma switch and the relays on the pcb, all are ok. does anyone have any info on these old machines please?
