There are many welding methods for welding two copper wires

1. Conventional argon arc welding can be welded by copper wire self-melting. If the copper wire is relatively large, it can be used 204 red copper argon arc welding wire is used as filler for welding.

2. Low-temperature welding is more suitable for novice welding methods. If the copper wire is very thin, use an electric soldering iron to weld it. You can use 1.3 WEWELDING M51 welding wire with M51-F flux for welding. If it is a copper wire, If it is relatively thick, it is heated with a flame, and then the welding wire is dipped in flux and applied to the welding part. The welding wire is completely melted and formed by heat conduction of the matrix.
