Micro Resistance - Dual Pulse CD Spot Welders

Micro Resistance - Dual Pulse CD Spot Welders

Available models are CD200DP, CD400DP, CD600DP. The dual pulse industrial capacitive discharge (CD) spot welder provides a substantially larger amount of weld energy combined with a finer range of power adjustment. As with Sunstone's other spot welders, the CDDP welders produces clean, strong welds. Pulse one heats the weld area to eliminate surface contaminants and seats the welding electrodes. Pulse two then makes a strong, secure weld. Both pulses occur within milli-seconds.

*Note about Tariffs (Updated May 1, 2025)

Sunstone is a home-grown, made-in-USA company. Most of our welders are engineered and built by skilled American workers who take pride crafting high-precision, highly robust welders. During manufacturing, Sunstone uses parts and materials sourced from U.S. companies whenever possible. In some instances, parts and materials may be sourced from outside the U.S. due to availability and cost. Unavoidably, recent tariffs have increased the cost of parts and materials.
To offset the increased cost in manufacturing, beginning May 1, 2025 Sunstone is adding a modest surcharge to affected products. The surcharge for this product is 193.45 and has already been added in to the purchase price. We will continue to monitor tariff costs and will happily adjust these down or eliminate them all together if possible.
