While it is absolutely possible to use the 1/8” tungsten and it will definitely handle the amperage a bit better, it really comes to down to preference as far as I’m concerned. You would need to make sure your machine settings reflect 1/8 tungsten versus say 3/32 to acquire better more calibrated arc starts. As a shop owner cost is a factor as well. If I had a hired hand in there blowing thru tungsten daily I’d prefer to pay for 3/32 versus 1/8. But it will absolutely get the job done.

tristan The 1/8” tungsten at amperage below 200 serves as a heat sink due to the shear diameter difference of the tungsten so the affected heat zone of the tungsten is smaller. As far as it affecting gas flow I’ve found that I do not see a significant difference above a 4 cup. 5 cup you may have to increase your argon a cfh or two but not enough to be significantly noticeable
