2.Description:
SJ501 is an an agglomerated aluminium-titanium type acidity flux (Rutile type), with alkalinity around 0.5-0.8. It is gray and round grain with mesh 10-60( 2.0-0.28m). It can be operated with AC and DC. the wire shall be connected to positive pole when applying DC. It has steady arc, nice weld formation, and easy in slag removal specially at high speed. The welding porosity scarcely occur.

It should be re-dried under 300-350℃ for 2 hours. Rust,grease and moisture on the weldment should be removed before welding.

3.Applications: 
When applied to various welding wires (such as H08A,H08MnA),it can weld low-carbon steel,low-alloy high strength structural steel.It can be welding boiler,ships,pressure vessel,mininature LPG tanks,vehicles,structural steels etc. Especially used for fast welding of thin steel sheet.
