The use of : welding steel structure, especially suitable for thin small pieces and short welds of discontinuous welding and smooth surface cover welding.
Characteristics: J421 is a rutile type coating acid electrode. AC and DC, can be used for all position welding. The welding operation is good, the arc is stable, the arc is easy, the slag is easy, the weld is beautiful and the splash is small.
Welding position:PA,PB,PC,PD,PE,PF
