Capacitor Discharge Welders from Weld Systems Integrators

• Low primary power requirement, relative to resistance welding.
• No Peak Energy Billing.
• 99.9% Power Factor means virtually no wasted welding current.
• Very fast weld time (typically under 10ms).
• Ultra-Fast Rise Time welds fast while minimizing heat-affected zone (HAZ).
• Tooling Often Lasts 3-5 Times Longer than other processes.

• Maximum current draw of 30 Amps for the welding process.
• 60 Amps or less Single-Phase Primary Power required for a complete machine.
• 100,000+ Peak Amps in under 5 milliseconds.
• Fast Follow-up Design allows for instantaneous response to weld set-down.
• No Water Cooling Required for Power Supply and Control. Tooling may require minimal cooling depending on final specifications.
• Fully-Monitored for Process Confirmation and Maintenance.
• Easy to use HMI User Interface.
• Robust, Reliable, Consistent Process.
• Welds with WSI CD Welders can achieve up to 200% Required Torque and Push-Out Values.
• Over 10 years of Consistent, Proven Results.
• WSI CD Welders are designed around customer applications, and are not ‘cookie-cutter’ machines.
• Specifications are determined by WSI engineers in WSI’s own welding lab, setting the standard for the industry.
• WSI CD Welders are designed for safe, easy operation by human operators, or for ease of integration into robotic cells. Controls, safety circuits, and guarding are engineered to customer specifications.
• WSI Single, Dual, or Multi-Head Welders are easily integrated with nut/part feeders, and are perfect for nut farms, and other high-density manufacturing operations.

Stand Alone Pedestal Capacitor Discharge Welders

These space saving machines are capable of welding the toughest of materials. They can be integrated with nut/stud verification devices, automatic fastener feeders and air over oil systems.

SINGLE STATIONARY HEAD	TWO SELECTABLE HEAD CONFIGURATIONS

Multi-Station Capacitor Discharge Welders

For multiple weld, low volume parts that could require tooling changeover, look at a multi-station welder from WSI. Each station can be set up independently – while still sharing one power supply to recognize cost savings and efficiency.
