Did you clean the MS? prepping the surface-wise ? try to bump up the argon a bit to 18-20cfh, try to use less heat depending on which machine you are using; some required more, some required less, need to find a pool and have a comfortable speed. On steels I use 1/16" tungsten typically SS I setup @ 33a and MS @ 48a, have encountered problems when didnt prep normally requiring more heat. Try some different settings, find a happy medium, most of all have fun
where are the rest of the fab from other members ????
