Hi Guys. I have a Hobart Beta Mig 200K1 which has developed a fault where by it behaves as if you have began to weld. The main contact and the gas soleniod click in (and out several times - sometimes) and the filler wire is live without touching the torch trigger. It does this even with the torch disconnected so I've sort of ruled the torch out. I have disconnected the coil wire on the main contact as someone said the contact was the fault, but the gas soleniod still clicks in and out at random as before. I fear the problem lays on the printed circuit board and wondered if someone could offer any advice as what to check bearing in mind I'm no electrician? Thanks.
