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 (0.197" to 1.181"). The HP200 portable model, mounted on a trolley, is
for wire 2mm to 6.50mm (0.079" to 0.256") diameter.
The videos can be viewed at the company’s website.
