ArcStar 101K3 AWS A5.29 E101T1-K3C-J
Characteristics and Applications: ArcStar-101K3 offers excellent arc stability and low spatter with CO2 shielding gas. It also has a fast freezing slag for all-position welding. These features, along with relatively low diffusible hydrogen levels, excellent slag removal, good impact values and high strength levels, make ArcStar-101K3 a superior choice for welding higher-strength steels.
Notes on usage: (1) Use (DC+) polarity. (2) Use 100%CO2, 20~25 l/min shielding gas. (3) Welding heat input must be controlled in order to get required impact value, since notch tough ness tends to decrease due to excessive heat input. (4) Keep dry during handling and storage.
