1.Description:
LH-HJ350 is a fused type medium manganese-oxide flux with vitreous granule of reddish brown to light yellow color about 8-40 mesh and 14-80 mesh in two sizes. It is suitable for use with AC and DCEP and it shows good welding usability.

2.Usage:
In combination with H08MnA, H10Mn2, H08Mn2Mo wires, this flux is suitable for welding of low alloy steel(such as 16Mn, 15MnV, 15MnVN) important structures , ships, boilers, high pressure vessels. The 14-80 mesh size is recommended forwelding of thin plates with small diameter wires.   

3.GUIDELINES FOR USAGE:
1.Dry the flux at 300-400ºC for 2 hours before use.
