Q
How big of machine do I need?
A
A 225 to 300 amp machine handles almost anything the average person will encounter, as most Stick welding procedures require 200 amps or less. To weld material thicker than 3/8 in., simply make multiple passes - this is what professionals do, even when welding on 1 in. structural steel.
