Applications

it is a metal cored wire for high speed single or twin tandem welding application
in the flat and horizontal fillet position. This wire benefits from high deposition rate and is widely used for shipbuilding, construction of bridge, and structural fabrication.

Characteristics on Usage

 has very low spatter loss rate and minimum amount of slag. It gives excellent
penetration and good arc stability. Especially has good anti-porosity to zinc-primer plate and mill
scale plate in high speed single and twin tandem fillet welding.

Welding Position                                   Current                          Shielding Gas

DC +                                                  CO₂

Notes on Usage

① Proper preheating(50~150°C)(122~302°F) and interpass temperature must be used in order to
release hydrogen which may cause cracking in weld metal when electrodes are used for
medium and heavy plates.
② Use 100% CO₂gas.
