I just welded my collet to collet body along with the tungsten & cracked my #6 cup.Well,thats never happened before.1/8" clean base metal,fillet weld.90 amps,15 cfh,1/16" tungsten.Ceramic cup was glowing red & tungsten burned up.This all happened in seconds.I was just practicing on some scrap before getting starting on a project.The base metal was clean.This is a new bottle of argon i might add.I have no idea what happened,any ideas?

The amperage was probably too high for that size electrode. Use the next size up electrode or crank down the amps to 80 or below for a 1/16" electrode.
That's my guess,anyway.

Got a new collet & body today & did some welding in between 80 & 100 amps with a 1/16 electrode.I think 100 amps is to much,85 good.Bottom line;what happened yesterday didnt happen today.Still dont know what happened.Max amperage to use with a 1/16 electrode?
