i have not mig welded in a while & whenI went to start restoring my mustang I found my welde to be Kaput, so i bought a low use miller matic 170. I checked it out before buying but I t just does not perform as I remember them . I hit the trigger which is very responsive & UI haer a blast of gas but then nothing more, I turn the valve on the bottle off & hitthe trigger again, the valve jumps a bit butdoes not fade to 0 as it should, I suspect that the maching is lettig a burst of gas out & then closing the valve/solenoid/whatever runs it. any thoughts?
as I weld, my first few seconds are great, then I start getting a mishmash of slag & puddles & holes, sounds like no gas right?
