Cold weld specialist PWM celebrates 40 years of service

British company PWM, which manufactures and supplies high-performance cold pressure welding machines and dies, celebrates 40 years of service to the global wire and cable industry in 2024.

The company’s original 1984 portfolio featured a hand-held cold welder for fine wire, a larger machine for medium wire and a pneumatically-powered rod welder. Today, PWM produces a comprehensive range of manual and powered machines for a variety of applications. Cold welding dies are individually hand-made in matched sets, in standard or custom sizes to suit round or profile wire. As a specialist manufacturer, PWM designs and builds its cold welding equipment in-house to stringent quality standards.

“We are proud to celebrate this milestone in the company’s history and I would like to thank the PWM team and our customers for their support,” said Steve Mepsted, managing director of PWM.

“Working closely with manufacturers to improve productivity, save resources and reduce costs has been a priority for the last four decades. We will continue to develop and deliver innovative cold welding solutions as the industry evolves.”

On-going research and development enables PWM to keep pace with manufacturers’ changing needs. The company introduced air/hydraulic cold welders on trolleys in the 1980s and 90s. User-friendly and energy-efficient, these mobile machines can moved easily to the work area, saving effort and reducing downtime. The 1990s saw a requirement for more powerful machines to weld large diameter rod. PWM’s “P1500”, for non-ferrous material up to 30mm, was the first hydraulically powered, electronically controlled, heavy-duty rod welder of its kind on the market. More recently, PWM developed the “CP180”, a small cold welder in a carry pack, and the “ST40”, an air/hydraulic welder for strip. PWM will launch a new cold welding machine designed specifically for trapezoidal wire at “wire 2024”.
