Features:

J421 is a carbon steel welding rod with rutile coating. It can be used for both AC and DC, and can be used for all-position welding. It has excellent welding process performance, good operating performance, easy arc ignition, stable arc, and beautiful welding seam shape.


Usage:

Welding low carbon steel structures, especially suitable for thin plate small parts and cover welding that require beautiful and smooth weld surfaces.


Precautions:

Under normal circumstances, the electrode does not need to be baked before welding. When the electrode gets wet, it must be baked at 150-170°C for 0.5-1 hour before use.
