Generally, the specification of tungsten electrode is 2.0 or 2.5/2.4mm, and cerium tungsten electrode is used. The current is controlled between 80~ 140, which is determined according to the plate thickness or wall thickness. Gas generally refers to the flow rate, and rarely talks about pressure. As long as the pressure in the bottle is not lower than 0.5MPa, the flow rate is generally 10~ 15L/Min. In general, the welding ferrous metal is DCEN, that is, DC connection.
