Cut rod costs with cold pressure

As energy and materials costs continue to rise, increasing numbers of wire and cable manufacturers are discovering that cold welding is an economical and efficient way to bond non-ferrous rod sections.

British company PWM, which has been at the forefront of cold pressure welding technology for almost 25 years, has developed three powerful rod welders to help manufacturers join rod quickly and cost-effectively. No heat, flux, filler or fumes are involved in the cold weld process, which creates a permanent bond stronger than the parent material. The EP500 model, one of PWM’s best-selling machines, is extremely easy to use and maintain. Virtually no operator training is required and the EP500, like all PWM machines, produces a reliable weld every time, reducing material wastage. Capable of welding copper rod from 5mm to 12.5mm and aluminium from 5mm to 15mm, the EP500 usually only requires maintenance every three years or so. PWM’s largest rod welder, the electro/ hydraulic P1500, offers an efficient and economical method of welding large copper rod sections up to 25mm in diameter (aluminium to 35mm). Power consumption is minimal and the P1500 guarantees a sound bond every time.

The hydraulic P1000 model is a compact but powerful machine with a small foot- print and a wide capacity ranging from 6mm to 16mm copper and 6mm to 20mm aluminium. Designed with a sloping front panel and angled mechanism for ease of operation, the P1000’s quick release dies and easily adjustable die setting ensure that die changeover is fast and problem-free. Most non-ferrous metals can be cold welded as well as various alloys. The cold weld process can also be used to join dis- similarmaterials, for example, aluminium to copper, and materials of different sizes. PWM’s UK-based specialist team is always available to provide advice and support on rod welding techniques and applications. PressureWelding Machines – UK Fax : +44 1233 820847
