1.it is a kind of high manganese and silicon, low fluorine fused flux.

2.Color:red brown to light yellow.

3.Grain size:of 8-40(2.5-0.45mm) and 14-40(1.5-0.45mm) meshes.

4.Current:alternating or direct current(welding wires must be connected with the positive electrode when direct current is used).

Usage:
1.for low-carbon and low-alloy steels like 16Mn and 15MnV, as well as ships, boilers and high-pressure vessels[applied to welding wires such as H08A(AWS EL8), H08MnA(AWS EM12) and H10MnSi(AWS EM13K)] 
2.for electro-slag and copper welding.

Cautions:
1.The oil stain, moisture, iron rust and other impurities must be removed from the surface.
2.Flux must be baked under 250~300°C for 2 hours before welding.
