Cutting &Welding
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
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,
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
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.
