It also works great on thinner guages of metal because you can turn the heat down so low and still get good penatration. Oxy acteline, or gas welding is great for thin metal and precision welds, also for brazing. and with the right tips can be used in cutting and bending metal.

TIG is not only for aluminum...its also for high carbon steel, stainless steel, or just cold rolled steel. TIG is used for high precise welds with excellent penetration and strength. Plus its user-controlled, means you controll the heat, gas flow, and the filler material, thus making a fine, precise, clean weld. MIG does not give the nice looking beads people see. Alot of people who fab exhausts, roll cages, intake pipes and etc use tig for the above reasons that i just stated. Also, if you dont catagorize 14g as sheet metal, you might want to hit the books again, and stop posting incorrect info.
