  • Maxstar 140 gas hose question

    I am fairly new to tig welding and am having an issue with my Maxstar 140. It works great on stick mode but I get nothing when I try to tig. I tested the switch and confirmed it is not the problem. I am using this machine on a 20A 110V and confirmed the power cord is connected and with proper polarity. I have continuity from the electrode in the torch to the gas fitting on the torch handle. I do not have continuity from the torch to the brass lug in the gas line. Should I have continuity through the gas hose? Attached is a photo for example..
