CDDP – High Power – Micro Resistance – CD Spot Welder

The CDDP industrial spot welders provide a substantial amount of weld energy along with a fine range of power adjustment. These welders provide up to 1100 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.

User manual



As with Sunstone Engineering’s other dual pulse spot welders, the CDDP industrial spot welders produce clean, strong welds. Each pulse can be adjusted to control the amount of energy released and can be turned on/off independently. Pulse one heats the weld area to eliminate surface contaminants and to seat the welding electrodes. Pulse two provides the energy to form the actual weld. Both pulses occur almost simultaneously with each weld initiation.

When combined with Sunstone’s new line of weld heads, the CDDP industrial spot welder can form strong, precise, and repeatable welds.
