1000ws & 1100ws Dual Pulse Capacitive Discharge Spot Welders

The 1000ws and 1100ws Dual Pulse Industrial Capacitive Discharge Spot Welders provide a substantial amount of weld energy along with a fine range of power adjustment. These welders provides up to 1000 or 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 applications.

As with Sunstone Engineering’s other dual pulse spot welders, the 1000 and 1100 watt second 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 CD1000DP can form strong, precise, and repeatable welds. Contact Us to learn more about this product.
