Equipment - Capacitive Discharge Welders

Single Pulse Laboratory Resistance Welders

Sunstone Single Pulse CD spot welders are designed to deliver welds for micro-scale to large-scale applications such as battery pack manufacturing.  The CD100SP 100 watt-second welder can be adjusted down to 0.015 watt-seconds (joules).  The CD100SP and CD200SP can also be adjusted up to 100 ws and 200 ws, respectively, to perform larger-scale welds.

Sunstone welder interface is easy to use and flexible enough to weld a wide variety of materials.  The welder is intended for use in a research laboratory or light production environment.

Sunstone's goal is to provide quality products at affordable prices for small and large businesses.
