https://weldmongerstore.com/ I remember way back to when I was in welding school, my instructor was always telling me to “watch the puddle”. Good advice even if he didn’t explain what I was supposed to be watching. Watching the puddle is one of the main things that tells you whether you are getting full penetration on an aluminum butt joint. You want to see the puddle sink a bit in between dabs of filler metal. This can be subtle but the more your eyes get trained, the more readily you can read

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
