Never had this problem before with dc tig, but while in a.c. it got really frustrating trying to work out why my weld looked like it was getting no gas, there wasn't even that much in it,
I tried more flow played with the settings like it was a HiFi, checked for leaks, then took the torch apart seen the dirt, there wasn't even that much, this was not on my own welder it's a firm I do work for now and again, i hate using it
