Product Description
JR-12 (Coverd Electrodes for Mild Steel)
Characteristics
JR-12 is a high-oxidant titanium welding rod with excellent workability and has a beautiful bead appearance.
In particular, the arc is quiet and smooth, creating minimal spatter and has fine slag removal.
It is suitable for welding light or thin-walled structure as the penetration is relatively shallow.
Purpose
General machinery, automobiles, Thin-walled structure, Thick-plate structure, Beauty Welding, Pipe, Water Tank
Operation precautions
Dry the cladding at 70~100℃ for 30~60 minutes if the arc turn unstable when it absorbed excessive cladding, performing unstable melting state, increased spatter, and undercutting or fitting.
Use within the proper current rage as welding at a current too high will reduce the X-ray performance, increase spatter, and cause undercuts.
