Last October I purchased an Eastwood 175 MIG welder. I tested it and all worked fine. I am now using it for some projects and after a while I found the gas valve does not always close when I stop welding. If I shut the machine off and turn it back on the valve stays closed.
The problem is intermittent so it does not happen all the time.
Unfortunately, I ran through a size 80 gas bottle in a few days and am not happy with that.
Is there a problem with the trigger? Valve? Disassembly does not look easy but it absolutely has to be fixed. Can someone point me in the right direction?
