11-3679 - Tweco 11-3679 Bridge Rectifier for Raider Welders

Technical Overview of the Tweco 11-3679 Bridge Rectifier

The Tweco 11-3679 Bridge Rectifier is a critical internal component designed specifically for the power regulation systems of Raider series welding machines. In the context of industrial welding equipment, the bridge rectifier serves the vital function of rectifying the transformer's Alternating Current (AC) output into the Direct Current (DC) required for stable welding arcs. This specific module is engineered to handle the thermal and electrical stresses inherent in heavy-duty welding applications, ensuring consistent voltage rectification and protecting downstream components.

Failure of a bridge rectifier in a welding power source often manifests as a complete loss of DC output, blown input fuses, or a severely erratic arc that makes quality welding impossible. The 11-3679 is an OEM (Original Equipment Manufacturer) specification part, meaning it matches the exact diode characteristics, voltage ratings, and mounting footprint of the original assembly found in Raider machines. Using non-OEM rectifiers can lead to impedance mismatches or thermal runaway, potentially damaging the main transformer or control boards.

Technicians repairing Raider units will appreciate the direct-fit nature of this component. It eliminates the need for retrofitting or modifying mounting brackets. The assembly is constructed with high-grade semiconductor materials encapsulated to resist dust, moisture, and vibration—common environmental factors in welding workshops and field sites. When diagnosing power loss in a Raider welder, the bridge rectifier is a primary inspection point, and the 11-3679 provides the reliable solution needed to restore the machine to full operational status.
