We are the expert of copper wire drawing machine in China, also we supply the drawing DIE, drawing capstan, cold pressure welder and related machine with best quality and low price, the cold pressure welder can be used to weld copper wires from 0.07mm to 8.00mm, aluminum wires from 0.07mm to 14.00mm. their main technical specification can reaches or surpasses that at home and abroad, facility you could compare our quality and unit price with PWM (England) s similar products.
The cold welder is a tool to joint nonferrous wires with the method of cold butt weld, there is no need to use electricity, heat, flux and electrode, thus saving such troublesome pretreating works of metal wire as cutting and cleaning the wire. It only needs to thread two wire ends into a welding die, to match a suitable die depending upon the size of the wire, and then to press the handle of the welder several times, finally the two wire ends get jointed. The result is the same as original wire, its tensile strength at the joint is good (equal to or even better than mother wire) and is not broken at the joint. Its resistivity is not bigger than that of original wire, therefore such welding is the best way to weld nonferrous wire.
