Notice:
1. The flow rate of shield gas should be within 20L-25L/min
2. The wire extension should be 15mm-25mm.
3. The surfaces to be welded must be cleaned away from impurities of oil contamination, rust, moisture, and so on.
4. The welding conditions mentioned above are for reference only and it is better to do a welding procedure qualification according to the project before putting it into formal welding
