Arc initiation issue - Everlast PowerARC 140st

admin

Hi everyone! I'm new to the site, and fairly new to tig welding. I am a hobbyist welder and just picked up my first tig, an Everlast 140st. I am comfortable with mild steel, and have had no problems with anything I've welded thus far…until tonight. I will be helping a buddy do some exhaust work on his car this weekend, and I need to weld a stainless exhaust tip to a piece of stainless piping (304). I grabbed a few scraps of 304 sheet from work (probably somewhere in the ballpark of .030" thick) to practice on since I've never welded stainless before. The exhaust tip and piping is about .050" thick, FWIW. For the life of me, with the welder turned down to 10 amps, I can't get an arc started! Once I turn it up to around 20 amps, it starts but burns right through the metal. My setup is as follows:17v torch6 cup1/16" tungsten (ground about 4:1)1/16" 308l filler rod100% argon ~20cfh of flowI will be either using flux core rod, or purging the pipes when I do the welding.I thought maybe it was the material for whatever reason (again, fairly new to this) and I couldn't get the arc started on mild steel either. I know for a fact this machine can weld at 10 amps because the video that sold me on the machine compared it to the Maxstar 150 and the guy welded at both the lowest end as well as the highest end of voltage on both machines, and they both performed very well. I couldn't come close to affording the Miller, so I went with the Everlast.Any help here would be greatly appreciated, thanks!MichaelLincoln Squarewave Tig 200Everlast PowerARC 140STCK130 Flex Head
