Product Description

Equivalent to Lincoln 780 welding flux ESAB OK 10.81
EN760 SA AR 1 88 AC H5                         
AWS A5.17 F7A0-EL12 F7A2-EM12K 

LH-SJ501 is a kind of aluminum-titanium-type sintered flux,BW=0.5-0.8,mesh 10-40(2.0-0.45mm),Either alternating or direct current can be used.It has hight rust resis-tance and the slag is easy to drop after welding. The welding bead is smooth and the welding technology has good performance.
When applied to various welding wires such as H08A,H08MnA,H08MnMo and H10MnSi,it can weld low-carbon steel,low-alloy steel and pressure vessel steel.And it is fit for fast welding of thin steel sheet like gas steel tanks and membrane water-cooled wall in boiler factory.
1.The oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.
2.The welding flux must be baked under 300-350
ºC for 2 hours before welding.
