Yes sir.....and although it was a simple fix, I really did change quite a few things along the way. Torch angle,not pulling the filler out of the gas shield area...etc etc. so ya, HELL YA..I got it.

Well I got it whipped now, My filler rod ( at the time 3/32) waaaaay to thick obviously bc no sooner than I switched to 1/16" the welds turned out beautiful. Nice color no nasty,ugly grey welds anymore. Hope this exp of mine helps someone else out there. Useing 3/32 red tungsten. Gas lens(do it...

I'm using a gas lens at around 18-20 cfh with the pedal pressed. Red tungsten
3/32. #8 cup 3/32 309Lss filler. I ordered some 1/16 filler BC I'm thinking that
3/32 is a little large for 1/16" SS SHEETMETAL. whitch I think is 304. I will try to turn the
Gas down a little and see.

]I recently took the advice of a few of you on this site and made some adjustments. Gas lens, bigger cup, lower heat. OK..why are half the welds still grey? Look like my torch angle maybe? Any help would be great. Thanks

I have a little project on my hands where I need to weld a SS bung for a back pressure sensor to a down pipe. The pipe looks to be plain steel or a low quality SS. it has traces of surface rust so I'm not sure. So is this the case where I would use a 3xxL filler rod?

I have Tigged up some SS with pretty good results, but I took the advice of a friend and the guy who puts on this website, Jody? And started with aluminum, then moved on to SS. If so, he's defiantly the best help/welder I've ever run across, so props to u man! At any rate, I was welding on some SS t...

I personally have used the green tip, junk IMO. I have used the 2% thoriated with the best results so far.
