I am new to tig welding and I recently tried my first tig on stainless. My father welds a lot of stainless and he finds it much easier to tig weld than carbon steel. Although only my first weld, I found it eaiser to see the puddle and see what was happening, but harder to control. Does stainless heat up faster? I was welding 1/8 inch at 125 amps, and this just seemed too hot. I am going off a welding calculator since I am beginning, and seemed like 100 amps was better. It was just a butt joint.  I could also not get a stacked dime look, just looked like a continous weld, not that it's bad, but why can I get that look with mild, and not with stainless. I also noticed that when I turned on the pulse feature of my welder, the dime look started happening? How do you get a pretty stainless weld without a pulser? What am I doing wrong? - If stainless does heat up faster, am I possibly moving too slow? If nobody understands without a pic, I will try to get one up tonight. Thanks!
Reply:yes stainless does heat up faster than mild steel. It doesnt distribute the heat as well as mild steel does. But for 1/8th material i think around 80-90 amps is good. To get the stacked dime look maybe just dab the rod into the puddle rather than lay it in there. You might already be doing that but i dunno. Hope that helps.

Reply:every machine is different, you just gotta use what you feel is a good heat. They just give you that for a ball park figure. They probably say 125 amps for 1/4" material or something
