Hello everyone ! New to forums, been reading about for abit now! So I have a sealey mightymig 100 gassless welder. I was doing some welding on the van and ended up the torch was abit messy by end so stripped it down to clean and I forgot to turn the power off when stripping the handle, idiot move I know. So the trigger wires ended up hitting a block of metal behind it which is used to Earth the torch gun. So after it touched, got a pop. Replaced fuse although was still powering up. Checked fuse on pcb. Replaced anyway. No joy, no welding current at torch and motor won’t feed wire on clicking it. I had a spare motor there and new pcb. Fitted both and still no joy. Pcb has the speed control module on it too. Tested motor and both work. Removed Earth from torch and ran new Earth to test. Issue still same. Won’t weld and motor won’t feed wire. Can’t see any burnt wires or anything that looks wrong?!? Only other thing I can think is Rectifier is blown?! any help would be great before i go buy a new one haha!
