Description:The copper-free welding wire completely solves the problem of copper pollution in the production process and the use process. The surface of the welding wire adopts special passivation technology, the surface is smooth, the rust prevention ability is strong, the wire feed is stable, suitable for long-term continuous welding.

when welding, the extension length of the welding wire should be paid special attention to, although too long can improve the welding coating rate, but will worsen the welding process and weld performance. Such as spatter increase, rough shape, etc. Suggestion: When the current is less than 250A, the extension length of the welding wire is about (10~18) mm; When the current is greater than 250A, the extension length of the welding wire is about (20~25) mm.
