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
