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

Have a project that requires you to weld aluminum? You don't necessarily have to reach for your TIG torch. Here are some tips from Ian Johnson to help you be successful when MIG welding with a spool gun. | ESAB North America

When you need to weld aluminum but don't have access to AC TIG or a spool gun, there is one process that can still get the job done, aluminum stick welding. Austin experiments with different polarities and pre-heat versus no pre-heat to see which produces the best welds over on YouTube today at 3:30 PM EST https://foxly.link/fsXzH4 | Weld.com
