PRECAUTIONS:
1. The groove of the weldment and the surface of the welding wire must be carefully cleaned before welding.
2. Generally preheat to 400~500 degrees before welding. Copper gas welding solvent must be used as auxiliary solvent during welding.
3. The welding flame should be a neutral flame or a slight oxidizing flame. The temperature during welding should be appropriately reduced, the welding speed should be increased, and the residence time of the molten pool at high temperatures should be minimized to reduce the evaporation and oxidation of zinc.
