Characteristics and Application
AWS A5.29 E111T1-K3CJ offers excellent arc stability and low spatter with C02 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 a superior choice for welding quench and tempered low alloy steels, such as ASTM A514, S690QL1 (EN 10025-6) etc.

Notes on usage:
1. Use DC(+) polarity
2. Use 100%C02, 20—25 1/min shielding gas.
3.Control welding heat input is critical for getting essential impact value, since notch tough ness tends to decrease under excessive heat input.
4. Keep the product dry, while it is stored or delivered.
