Weld Systems Integrators, Inc (WSI), a major U.S. manufacturer of resistance welding equipment, announced a new mid-frequency direct current (MFDC) press type resistance welder. This new addition to the WSI product line incorporates a Fast Rise Time (FRT) MFDC transformer. The FRT-MFDC machine is suitable for welding applications requiring short weld times and high welding current.

FRT-MFDC welders offer the following benefits: reduced life cycle cost, better process control for welding coated parts, weld nugget management, minimized heat affected zone (HAZ), and lower primary power requirements.

These benefits make FRT-MFDC resistance welding equipment an excellent solution for the following applications:

• Ring Projections

• Weld-Through Sealers

• Hot Dipped Materials

• Minimized Heat Affected Zone (HAZ)

• Galvanized Steels

• Hot Stamped Boron Materials

• Aluminum

• Nut and Stud Welding

• High Strength Low Alloy (HSLA) Steels

WSI designs, engineers, and manufactures its FRT-MFDC resistance welding equipment in the United States using domestically sourced components. This enhances serviceability and support by eliminating delays in parts and repairs.

WSI has installed the latest FRT-MFDC resistance welding machine in the WSI Welding Laboratory for customer training and process development alongside a full range of resistance welding equipment including CD, MFDC, and AC machines for weld trials and part development.

WSI’s offices, welding laboratory, engineering, manufacturing, machine parts and consumable warehouse are located under one roof in Warrensville Heights, Ohio.
