CHT611 flux cored wire in line with: GB / T10045 E431T-G AWS A5.36 E61T-C1AZ-CS1 described; CHT611 case of titanium slag system CO2 gas shielded flux cored wire. Excellent welding performance, stable arc, little spatter, easy slag removal, weld appearance, excellent all-position welding performance can also be vertical down welding. Use: for mild steel and the corresponding strength low-alloy welding, such as: pressure vessels, shipbuilding, petroleum and chemical industry.

The use of CO2 gas, CO2 gas purity of 99.98% or more . 2. When welding CO2 shielding gas flow rate should be controlled at 20-25L / min. 3. The extension length of the wire is controlled within the range of 15-25mm.
