However, once one masters the art of TIG welding, there is no more efficient way of working with metals that require high temperatures to weld. Certain stick welders can be converted to TIG welders through the addition of an air-cooled torch and a bottle of argon. Here we have compiled a list of the 4 best TIG welders for aluminum on the market:

Aluminum Welding Tips
In terms of rod choice, a 4043 filler rod (see them here) is generally the best overall choice. It gives a good balance of cost and availability, as well as crack sensitivity. When welding aluminum, professionals often resort to a 50/50 mix of helium and argon; this technique appears to be the staple of the industry and should definitely be looked at. Any aluminum alloy must be extremely clean, no dirt whatsoever, so wipe the surface as cleanly as possible. It should also be noted that you will not get away with carrying out any bad habits brought from steel welding when working with aluminum. It is extremely sensitive and meticulous precision is needed when welding. Good luck!
