Greener welding options
from PWM
Cold welding offers wire and cable manufacturers a greener,
more economical method of bonding non-ferrous wire and strip.
The process takes place at ambient temperatures, so no dangerous
or unpleasant fumes are generated and because cold welding
creates a strong and reliable permanent bond, it also reduces
material wastage and energy consumption.
British company PWM, which celebrates 25 years of service to the
wire and cable industry this year, has developed a comprehensive
range of high performance cold welding machines and dies,
designed and manufactured in its own workshops to high standards
and specifications.
PWM produces manually operated hand-held and bench-mounted
models, versatile trolley-mounted machines and large electro/
pneumatic and electro/hydraulic powered rod welders.
Welding capacities range from 0.08mm diameter up to 30mm
diameter copper/aluminium.
Precision engineered to provide strong reliable permanent bonds
every time, PWM cold welders are very easy to operate. PWM’s best
selling HP100 can now be supplied in automatic form.
The machine, which has a capacity of 1mm to 5mm diameter copper/aluminium, can operate in normal or automatic mode. Normal
mode requires the operator to load the material and press the foot pedal four to six times to complete the weld. In automatic mode,
the operator simply loads the material and presses a button
and the machine does the rest.
The majority of PWM’s smaller welders are manually
operated, and even the powered models in the range are
extremely energy efficient compared with electrical butt
welders.
PWM’s powerful P1500 machine, for example, can weld
copper rod up to 25mm diameter and aluminium to 30mm
diameter, yet requires only a small current to drive the
hydraulic pump motor.
