Description:
CHF43/H08A is a fused type flux with high - manganese, high - silicon low
fluorine. It is suitable for both AC
and DC power sources. The welding wire should be connected to positive
pole when it is used for DC only. It is able to provide excellent
performances on welding due to its stable arc.
|
Application:
In combination with CHW-S1(GB H08A, AWS EL12) wire, it is
suitable for welding if ship structures as well as boilers, pressure vessels,
pipes etc.
