The thickness of metal you can weld with a wire feed welder (MIG welder) depends on the machine's power and the type of wire used. Generally, a typical 120V MIG welder can weld steel up to about 1/4 inch thick in a single pass, while more powerful 240V machines can handle up to 1/2 inch or more. For thicker metals, multiple passes or specialized equipment may be required.
