Cutting &Welding

Cold comfort

Cold pressure welding offers modern wire and cable manu- facturers many benefits. Compared with electrical welding, the process is quick, clean, ‘green’ and economical and creates a reliable, per- manent weld stronger than the parent material without sacrificing electrical integrity. British company, PWM, de- signs and manufactures cold welders for a variety of appli- cations. Durable, simple to operate and easy to maintain, all PWM machines and dies are

enabling welding to take place where space is very limited, at a strander lay plate for example, or inside a spooler casing. PWM’s larger wel- ders provide an economical method of joining large rod sections. Thepowerful P1500, capable of joining large copper rod up to 25mm diameter and aluminium up

The HP100 cold welder is powered by an air/hydraulic intensifier and trolley-mounted for convenience ▲

precision engineered in the company’s own workshops, ensuring total quality control and accountability. PWM’s hand- held manual models are ideal for repairing wire breaks quickly and efficiently in confined spaces. Designed to be comfortable to hold and operate, the M10, M25 and M30 machines have capacities of 0.10mm to 1.80mm diameter copper/aluminium. Trolley-mounted models can be brought to the weld area, saving time, effort and labour. The air/hydraulic HP100 machine has a welding capacity of 1.00mm to 5.00mm on copper/ aluminium. The solid steel welding head can be portable,

to 30mm, only requires a small current to drive the hydraulic pump motor. The compact P1000 model, which takes up little factory space due to its small footprint, has a wide capacity of 6mm to 16mm copper and 6mm to 20mm aluminium. Quick release dies and an easily adjustable die setting mecha- nism ensure that die changeover is fast and problem-free.
