Attention:

1. After welding must put in order interface and welding wire surface, must welding torch preheat 400-500 welding

2. Welding must use cooperation copper gas weld flux

3. Welding flame must use neutral or light oxide fame, suitable reduce welding temperature, raise welding speed, reduce flux stop time in high temperature in order to reduce zinc evaporate and oxide.
