K-439T description:
Wire is a metal type of flux cored wire for high speed welding on the plate as possible.
It would produce a moderately soft arc and low spatter generation.
Slag quantity is almost the same as solid wire and deposition rate is up to 20% higher than solid wire's one.
K-439T has the high tensile strength at the high temperature atmosphere.
The shielding gas should be used 98%Ar+2%O2 for welding.
