One important technique for tig welding stainless steel is to get the puddle started quickly and to get moving quickly before too much heat builds up. Because stainless steel is not very thermally conductive, heat does not dissipate quickly and its easy to overheat. In this video, you will see getting a puddle started quickly at 120 amps and after 2 or 3 dabs, reducing amperage to around 90 amps on .120 wall stainless tubing. Also toward the end of the video, you will see the importance of purgi
