【GC·J422】
J422 is a carbon steel electrode with calcium titanium
coating.It can be used for both AC and DC, and can be used for
all-position welding. The welding process is excellent,the arc
is stable, spatter is small, slag removal is easy,arc re-ignition
is easy, and the weld shape is beautiful.
Mainly used for welding low carbon steel
structures and low alloy steels with low strength levels.
It is generally used for welding steel structures and
ordinary carbon steel pipes.
