Cold pressure welder for non-ferrous strip - cable armoring lines

The ST40 is PWM's air/hydraulic cold pressure welder designed specifically for non-ferrous strip and tape used on cable armoring lines. Fast and user-friendly, it requires no set-up time and is activated by a simple foot pedal. The machine is trolley mounted so that it can be easily moved around the work area.
A notable feature of the ST40 is its dual-orientation welding head, which can be positioned either vertically or horizontally to suit the operator's requirements and line configuration.
