PWM’s innovative TR45 cold welder for trapezoidal wire will be exhibited at Interwire for the first time on booth 1057, alongside the company’s best-selling EP500 rod welder and a range of smaller powered and manual machines. The products will be presented by Joe Snee Associates, exclusive distributor of PWM cold welding equipment, spares and dies in the US and Canada.

The TR45 is designed specifically for welding non-ferrous trapezoidal wire up to 45mm² (0.0697 sq.in.) cross-sectional area. Powered by an advanced air/hydraulic system, the TR45 is energy-efficient and straightforward to operate. No set up is required and the mobile machine can be wheeled easily to the work area, saving effort and reducing downtime.

PWM’s electro/pneumatic EP500 cold welder provides a cost-effective method of welding large non-ferrous rod sections. The machine has a wide capacity of 5mm to 12.50mm (.197″ to .492″) copper and 5mm to 15mm (.590″) aluminium, and is quiet, clean and energy efficient.

Other cold welders on show include the air/hydraulic HP100 machine, for effortless welding of wire 1mm to 5mm (.039″ to .197″), and the manually operated M101 for copper wire 1mm to 3.60mm (.040″ to .141″) and aluminium 1mm to 5mm (.197″). The M101 can be used on a workbench or supplied with a cart.

The smaller M30, for manually welding wire or strip within the range 0.30mm to 1.80mm (.0118″ to .071″), can be hand-held or fixed to a bench. For finer material 0.10mm to 1.20mm (.0039″ to .047″), PWM offers the hand-held M10 and M25 machines and the BM10 and BM30 models, which can be used on a bench or with a cart.
