1 wire into the plant must be stored in a dry environment, not just open the diskwaterproof wire welding package2 should be removed before welding surface of the oil,rust, moisture and other impurities
3. The use of CO2 gas, CO2 gas purity of 99.98%.
4 CO2 protection welding gas flow should be controlled in 20-25L/min.
5 out of wire length should be controlled at 15-25mm range.
6 to be preheated before welding to 150-300 ℃, after welding to be tempered by 700-740 ℃.
