This depends mainly on three things. One is the thickness of the metal. Another is the kind of metal, and third is what type of joint you're welding. The easiest machine to use is a wire feed welder. If welding aluminum, be sure to use a spool gun or it will likely clog the lines. If you don't know what settings to use for the thickness and type of metal you are welding, it's a good idea to test it first on a scrap piece of similar type an thickness. Also, be sure to strength test the weld after it is completed especially if it is in a load bearing joint. If you are unfamiliar with the welding process, it's best to educate yourself on the process itself first before attempting to weld anything of value.
