I've had my berlan mig140 for years now trouble free. And just yesterday it now arcs without pulling the trigger. Never did this before. Is it something in the torch or in the welder that has gone?
Any help appreciated
doubt very much it will be the transistor, desolder the relay then remove the cover you will soon see if its fused togetherCheers guys for the quick reply tried to listen for the relay doesn't seem to clicking so I'll try and get another one and replace it. And maybe the transistor for luck too.
Cheers
Guys
