Notes: |
1 wire into the plant must be stored in a dry environment, not just open the disk waterproof wire welding package 2 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 ℃. |
