The Advantages of Capacitive Discharge Spot Welders
Capacitive discharge spot welders, also called capacitive resistance or Capacitor Discharge spot welders, have many advantages over other welder types:
Capacitive Discharge spot welders are one of the most cost-effective welding solutions for fine-spot resistance welding. Whether you are manufacturing battery packs or microscopic assemblies, Sunstone Capacitive Discharge spot welders are the most affordable, precision fine-spot resistance welders on the market.
1000ws Dual Pulse Capacitive Discharge Spot Welders
The 1000 Dual Pulse Industrial Capacitive Discharge Spot Welders provide a substantial amount of weld energy along with a fine range of power adjustment. The CD1000DP provides up to 1000 watt-seconds of energy for thicker, more conductive, and highly-resistive materials. For applications that may require additional weld energy, the unit can be upgraded to provide up to additional 100ws of energy. 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 Watt Second spot welder produces 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.

The 600 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 Engineering’s other spot welders, the 600 Watt Second spot welder produces clean, strong welds. Pulse one heats the weld area to eliminate surface contaminants and seat welding electrodes. Pulse two then makes a strong, secure weld.

The 400ws Dual Pulse Capacitive Discharge (CD) Resistance spot Welder is one of Sunstone’s most popular welders for resistance spot welding. 400 watt seconds of weld energy provide ample power for a large spectrum of applications, including battery pack manufacturing, at an affordable price. The Dual Pulse feature is preferred for clean, strong resistance spot welding. Pulse one heats the weld surfaces to eliminate contaminants. Pulse two then performs the actual weld. Both pulses occur within a tenth of a second.

Typical CD400DP Resistance Spot Welders Applications
The 200 Dual Pulse Capacitive Discharge Fine-Spot Resistance Welders provide the ideal resistance spot welding equipment. The 200 watt second fine-spot resistance welder combines affordability and power. The welder’s Dual Pulse Feature aids in the welding process. The first pulse heats the weld area to eliminate contaminants and then seats the weld electrodes. The second pulse is a higher energy weld that performs a clean, strong weld. Both pulses occur within milli-seconds.

The D-CD320 has been designed for maximum versatility and productivity The D-CD320 offers both DC and CD waveforms. The DC mode is ideal for thermocompression bonding applications – especially when welding magnet wire or enamel coated wires. Weld output can be adjusted up to 12V or as low as 0.2V, with a pulse width that can be adjusted from 500ms down to 0.5ms.
In addition to the DC mode, the D-CD320 can be used as a normal CD welder for a variety of resistance welding applications. The CD mode offers a smooth weld energy discharge curve that ensures strong weld nuggets and smooth weld surface formation. Total energy ranges from 320 watt-seconds down to 0.1 watt-seconds.
Both weld modes offer dual pulse welding capabilities. The dual pulse function of these welders offer some key benefits for many applications. Pulse 1 can be used to melt away wire enamel coatings or to preheat a weld spot – thus cleaning off contaminates from the part surfaces. In either application, pulse 1 helps prepare the pieces and facilitate the weld process to help improve the overall welding process and nugget formation.
Depending on the needs of the particular application, Sunstone Engineering offers a variety of weld heads and micro-force weld heads that can be used with the D-CD320. Please Contact Us to learn what system recommendations we have to offer for your particular application.
