Explanation: JH-SJ503 is a aluminum-titanium type acidity agglomerated flux,alkalinity around 0.7.It is gray and round grain,with grain size around 1.18~0.28mm.It can be operated with DC,the wire to be connected to negative pole.It has steady arc, nice weld formation,and easy in slag removing, as well with perfect deposit metal impact toughness.
Applications:Accompanying suitable wires of H08A,H08MnA,etc. to weld normal low carbon steel and some low alloy steel strutures.It suits welding of medium thickness steel structures,can be used for multiple layers welding, single wire welding or multiple wires welding,

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.
