WebbTypically, most of the Stick (Shielded Metal Arc Welding, or SMAW) welding processes draw 200 amps or less. So, a stick welder with 225 to 300 amp can handle almost anything the average user may encounter. Simply make multiple passes to weld a material that is thicker than 3/8-inch. Even when welding on a 1-inch thick structural steel, you can ... Webb6 jan. 2016 · The obvious one is when the only available power supply has AC output only. This is typical with low-cost, entry-level welding machines, such as the “buzz box” welder. “Also, there are some specific technical problems associated with using DC polarity, and number one is arc blow,” says Eric Stewart, pipewelding technologist at Lincoln .
