CO2 is the use of titanium-based flux-cored wire welding. Deposited efficient performance of all-position welding process better, legislation can also be welded down. Applicable to ships, pressure vessels, mechanical equipment, steel bridges, such as low carbon steel and 490MPa high strength steel welding class.

Please be noted:
Wire shall be stocked in dry.open the packs just when welding to avoid the wire rust.Before welding please clean out the oil,rust,water etc from the work parts
3.The protection of the use of CO2 gas, CO2 gas purity of 99.98%.
4.CO2 welding to protect the flow of gas should be controlled in 20-25L/min.
5.Extend the length of the wire should be controlled in the range of 15-25mm.
6.Preheating before welding to 150-300 °C, PWHT 700-740 °C tempered by the need to deal with.
