PWM, leading manufacturer of cold pressure welding machines and dies, has produced a series of videos demonstrating four of its high-performance cold welders in action.

The videos show how PWM’s P1500, P1000, EP500, and HP200 cold welders utilise the multiple upset technique to create strong, permanent welds on copper and aluminium wire and rod, without heat, flux or fillers.

Steve Mepsted, Managing Director of PWM, said: “We have been manufacturing cold welding machines and dies for over 25 years but still find that many wire and cable manufacturers are unfamiliar with the process and the benefits it offers. Cold welding is cleaner and easier than electrical welding and also more cost-effective, particularly for joining large rod sections up to 30mm diameter.

“The videos give manufacturers an opportunity to watch the process from start to finish. They can see how our user-friendly machines operate and view the welds produced by our precision-engineered UK-made dies. These welds are reliable, consistent and stronger than the parent material, and the electrical integrity of the material is not affected.”

PWM’s EP500, P1000, and P1500 freestanding rod welders cater for wire/rod sizes from 5mm to 30mm (.197” to 1.181”). The HP200 portable model, mounted on a trolley, is for wire 2mm to 6.50mm (.079” to .256”) diameter.
