Main Product

CDDP-A Industrial Spot Welders

The Sunstone CDDP-A uses capacitors to store and release weld energy you’ll renjoy highly repeatable welds unaffected by line voltage fluctuations. Additionally, you’ll achieve quick energy release for welding highly conductive metals such as copper, yet only generate a small heat signature or heat affected zone.

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.
