Cold Pressure Welding

Cold pressure welding is a method for permanently joining nonferrous metals and their alloys without using heat, fillers or fluxes. Round wire or rod sections, dissimilar materials, and materials of different sizes can all be welded with PMW's proven cold welding technology. The cold welder produces a weld that is stronger than the parent material without sacrificing electrical integrity. Huestis Industrial distributes PWM's complete line of welders and dies.

PWM Handheld
Cold Pressure Welders

Handheld Manual Welders are lightweight and ideal for use in confined spaces to permanently weld most nonferrous metals. Two models handle materials in the .0031” - .045” (0.08 - 1.20 mm) range. Designed to fit comfortably in the hand, these machines are easily operated by a light trigger action. Each unit uses the proven multiple upset technique to complete the cold pressure weld in seconds. All units use industry standard dies and are supplied with their own storage case that includes additional space for multiple dies.

PWM Portable, Scissor Action
Cold Pressure Welders

Portable Scissor Action Welders are convenient and powerful. The portable, manually operated M30 welds most nonferrous metals in wire or strip form, within the .0118” - .071” (0.30 - 1.80 mm) range. It is the smallest machine manufactured to date with this impressive size range capability. The M30 uses industry standard dies and is operated by a simple scissor action. It uses the multiple upset technique to complete the weld in seconds. While designed to be handheld (the machine is perfectly balanced for ease of use) the M30 also has the adaptability to be statically mounted in the work area if required. It is supplied in its own storage case, with space provided for a number of dies.

PWM Pneumatic, Handheld
Cold Pressure Welders

Pneumatic Handheld Welders provide an effortless, fast and permanent weld for nonferrous materials, in wire or strip form. PWM's new HP30 has a capacity of .0118” - .071” ( 0.30-1.80 mm) for copper, and .0118” - .0787” ( 0.30 - 2.00 mm) for aluminum. Freestanding and portable within the limits of the air supply, the HP30 can also be supplied with a mounting kit, for secure or permanent fixing to a work surface or trolley. The compact HP30 measures 6.30” (160 mm) long x 3.23” (82 mm) wide x 12.68” (322 mm) high, and weighs just under 9 lbs. (4.0 kg). The machine is supplied in a convenient, custom case incorporating pockets for several die sizes.

PWM Manual
Cold Pressure Welders

Manual Welders can be used on either a work bench or a mobile trolley. (Trolley can be supplied.) These small sturdy machines are manually operated using light hand pressure on the operating lever to initiate the multiple upset technique. These machines use industry standard dies and have the capacity to weld most nonferrous metals within the .004” - .071” (0.10 - 1.80 mm) range. This uncomplicated design is both simple to use and very tough. Due to the few component parts used, it is extremely reliable and low on maintenance.

PWM Pneumatic
Cold Pressure Welders

Pneumatic Welders are mounted on specifically designed trolleys that allow easy portability and full view of the weld area. The machines use industry standard dies and weld most nonferrous metals in wire or strip form in the range of .040” - .197” (1 - 5 mm), depending on hardness. One totally pneumatic model and one air/hydraulic model use compressed air to activate the machine. These strong, simple designs offer outstanding reliability, and ease of maintenance.

PWM Pneumatic/ Hydraulic
Cold Pressure Welders

Pneumatic/ hydraulic welders offer powerful performance. PWM's HP100 model is equipped with a solid steel welding head capable of welding non-ferrous wire and strip from .039” up to .197” (1 - 5 mm). Trolley-mounted for convenience and ease of use, the HP100 is powered by an air/hydraulic intensifier and easily activated by a foot pedal. Using the proven multiple upset technique, the machine will cold weld the materials in seconds to provide a bond which is as strong as the parent material.

PWM Pneumatic/ Hydraulic
Cold Pressure Welders

Pneumatic/ hydraulic welders offer powerful performance. PWM's new HP200 model is a larger, more powerful version of the HP100, equipped with a solid steel welding head capable of welding non-ferrous wire and strip from .079” up to .256” (2 - 6.5 mm). Trolley-mounted for convenience and ease of use, the HP200 is powered by an air/hydraulic intensifier and easily activated by a foot pedal. Using the proven multiple upset technique, the machine will cold weld the materials in seconds to provide a bond which is as strong as the parent material.

PWM Electro/ Pneumatic
Cold Pressure Welders

Electro/Pneumatic Welders handle most nonferrous metals, in wire or strip form, in the range of .197” - .492” (5 - 12.5 mm)for copper, and .197” - .590” (5 - 15 mm) for aluminum depending upon hardness. Operation is controlled by an advanced and easy to use Programmable Controller (PLC) which takes the pneumatic system through the required welding sequence. A coaxial thrust technique is applied in the welding process, with independent control over the grip and upset movements through an arrangement of pneumatic cylinders. Fully automatic deflashing is incorporated into the system for removal of the weld burr. It is easy to use, totally reliable and ensures a clean and safe working environment for operators.

PWM Electro/Hydraulic
Cold Pressure Welders

Electro/Hydraulic Welders handle most nonferrous metals in a wide range of sizes. Choose the P1000 model for .236” - .630” (6 - 16 mm) diameter range for copper, and .236” - .787” (6 - 20 mm) for aluminum. The P1500 steps up to a larger range of .590” - 1.00” (15 - 25 mm) diameter for copper and .590” - 1.180” (15 -30 mm) for aluminum depending on hardness. Both systems are hydraulically powered and electronically controlled. The independent grip and upset forces are produced by an arrangement of hydraulic cylinders. Concentricity of the two work pieces is ensured. The control system provides automatic deflashing on completion of the weld. An important feature is the low electrical consumption for welding large cross sectional areas. These robust welders are simple, safe, reliable, and quiet in operation.

Industry Standard Dies

Industry Standard Dies work with all cold pressure welders manufactured by PWM as well as other popular cold pressure welding systems.

We can supply industry standard dies for wire sizes between .0031” - .197” (0.08 - 5 mm) in size. All dies are individually handmade in matched sets to the tightest possible tolerances by skilled craftsmen. Dies can be provided to suit round or profile wires and rods according to customer specifications.
