PW.SJ101 flux is a kind of fluoric-alkali sintered flux, with basicity of 1.8 and the grey rounded grain size of 2.0-0.28mm (10-60 meshes). During application, the arc is stable, and the removal of slag is easy. Welding bead is nice. The deposited metal has good low temperature toughness. The wires can work on AC/DC and must connect to the positive terminal on DC current while using DC.


Working with the proper welding wires (EM12K, EH14, EA2, and EA3) or (wire H08MnA,H10Mn2,H08MnMoA,H08MnMo2A etc)can weld multiple kinds of alloy steel structures such as ship body, pressure vessel, boiler, pipeline etc.

1. The welding electrodes should be baked 1.5 hour at 300~350℃ before welding.

2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.
