Hello all, so I have a Invertec V160-T Pulse tig/stick welder. the problem I am having is the argon continuously flows out of the nozzle even with the machine off. after talking to the Lincoln tech support and trying their troubleshooting suggestions, they think the power control board is malfunctioning and will need replacement. I guess it’s a common problem with these machines. If I were to get a new PC board it’s about $1100+ which is wayyyy out of my budget currently.

I’ve looked on eBay and I haven’t had any luck finding one for any less than the new price, I’ve heard of people with this problem putting some sort of foot-switch to control the gas flow problem. It doesn’t sound like a real smart idea if something were to short circuit and fry the welder.

My question is, Has anyone else run into this issue? What were your solutions? Any ideas will help. Thanks a lot! - Otis
