Cutting & welding Cleaner, greener welding

Cold pressure welding has many benefits. Compared with electrical welding, the process is quick, clean, ‘green’ and cost effective and creates a reliable, permanent weld stronger than the parent material without sacrificing electrical integrity. PWM, which has been at the forefront of cold pressure welding technology for over 30 years, has developed a comprehensive range of robust, reliable machines and dies suitable for a variety of applications. PWM dies, which can be standard or custom made to suit round or profile wire and rod, are precision engineered in the company’s own workshops, ensuring total quality control and accountability. PWM’s most recent intro- duction is an upgraded version of its powerful electro-hydraulic P1500 rod welder, launched at wire 2010. British company

The new P1500 ▲ ▲

The new P1500 has an improved hydraulic operating system that provides a quieter, smoother weld operation. The machine also incor- porates a new user-friendly operator keypad. Power consumption is limited to the hydraulic pump motor, making the P1500 very energy efficient and economical to operate. The P1500 weld cycle takes only minutes and the machine has a capacity of 15mm to 25mm diameter copper and 15mm to 30mm aluminium. The PWM range includes two smaller rod welders, the P1000 (6mm to 20mm) and the EP500 (5mm to 15mm) as well as manual hand-held and bench-mounted machines, and trolley-mounted machines (manual and powered) for wire sizes from 0.1mm up to

6.5mm. Cold welding can be used to bond most non-ferrous metals, as well as various alloys. The process can also be used to join dissimilar materials, for example, aluminium to copper, and materials of different sizes. PWM’s UK-based specialist team is always happy to provide advice and support on cold welding techniques and appli- cations and the company’s worldwide network of experienced agents offers international wire and cable manufacturers a fast and efficient service.
