0558006151 - ESAB 150A 600V Dual IGBT Power Module

Restore Power to Your ESAB Inverter

The ESAB IGBT Dual 150A 600V (0558006151) is a critical power semiconductor component designed for the repair and maintenance of high-performance welding inverters. As the heart of the power switching stage, this Insulated-Gate Bipolar Transistor (IGBT) module manages the high-speed switching required to convert input power into the precise welding current needed for stable arcs. When an IGBT fails, your machine will typically lose output power entirely or display error codes related to the power stage.

This specific module features a dual configuration, integrating two IGBTs into a single robust package. It is rated for a continuous collector current of 150 Amps and a collector-emitter voltage of 600 Volts. These specifications make it suitable for demanding industrial environments where thermal cycling and electrical loads are significant. Using genuine ESAB repair parts ensures that the electrical characteristics—such as switching speed, saturation voltage, and thermal resistance—match the original design of your welding power source.

Replacing a blown IGBT is a common repair for inverter-based welders. It is highly recommended to check the gate driver circuits and other associated components when replacing this module, as failures often cascade. Proper installation requires the application of high-quality thermal compound to the baseplate to ensure efficient heat transfer to the machine's heatsink. This component is engineered to restore the efficiency and reliability you expect from your ESAB equipment.

Technical Highlights

• High Efficiency: Low saturation voltage reduces heat generation during operation.
