Hello all,
Looking for a little insight into an issue I'm having with my little chinese DC inverter TIG welder.
After ruining the connections on my torch trigger switch I now have the following problem: With a new torch fitted (to rule that out) I turn the machine on, fan runs like normal, but the torch seems to be 'live' already without depressing the trigger. Gas is flowing already as well. Placing the tungsten very near the workpiece yields arcing/stuck electrode. So why is my torch 'live' before I ask for it to be? I think the issue lies within the High Frequency circuit but visually I see no evidence of foul play. I am new to these things but can use a volt meter if pointed in the right direction. Thanks for ideas, suggestions, etc...in advance.
