Main Product

CD1000DP Industrial Spot Welders

The CD1000 dual pulse industrial spot welders provide a substantial amount of weld energy along with a fine range of power adjustment. These welders provide up to 1000 watt seconds of energy for thicker, more conductive, and highly-resistive materials.

Weld energy can be adjusted by increments of 10ws making it extremely versatile for a variety of industrial spot welding applications.

250i2 EV CNC Battery Welding System

The 250i2 EV is perfect for welding copper tabs on battery packs.

The 250i2 EV has a new design to give superior performance. This newest update takes all of the great features from our previous EV copper tab battery welder, and adds to it a new motorized weld head for greater control, precision, and uniformity to every weld. The power supply has also been upgraded to offer superior control and fine-tunabilty to guarantee the perfect weld can be achieved.

Manufacturers can produce lighter, more compact, and more efficient battery packs without compromising power or capacity.
