Explanation：JH-SJ102 is a soda-fluorine type agglomerated flux, alkalinity around 3.0.It is gray and round grain, with grain size around 2.0~0.28mm.It can be operated with DC,the wire to be connected to positive pole.It has steady arc, nice weld formation,and easy in slag removing, as well with perfect deposit metal welding technological characteristics.
Applications:Accompanying suitable wires (H08MnA,H10Mn2,JH-WQ1,JH-WQX2,etc.),mainly applied in the welding of low alloy steel,high strength steel structure(like16Mn,14MnNbq,WQ490E,Q345C,etc.)and the submerged welding of boiler pressure vessels, ships, bridges, oil transportation lines,etc.Its deposit metal owns perfect low temperature impact toughness.IT can be used for the submerged welding with multiple layers,double sides single layer,multiple wires, and narrow gap.

Points of Attention：
1 The fluxs to be dried 2 hours in 300℃~350℃.
2 De-rusting, water and oil cleaning ,as well other impurities removing of the work be done before welding.
