Most high-power machines have DC capability but because of its low melting point and other special features it cannot be used to weld thin materials like aluminum. Since youre going to weld aluminum using TIG welding youll need to choose either the DC positive or DC negative power. When done correctly TIG welding aluminum can produce quality welds.
Im gonna set it up on a positioner and Im gonna compare penetration same amperage 50.
I have recently purchsed one of those 4 in 1 Mitec welders 1345 I have the argon and I have seen sites that talk about 20cfh thats about 40LPM its quite high. Even with a simplified TIG welder like the Eastwood TIG 200 ACDC. If you are doing TIG welding then be sure to clean each wire before you use it. This process also allows more control over tricky welding variables like heat penetration and overall aesthetics.
