0464503880 - ESAB Warrior Inverter IGBT Power Module Set

Genuine ESAB Power Electronics for Industrial Reliability

The ESAB IGBT Module Set (0464503880) is a critical replacement component designed specifically for the ESAB Warrior series of multi-process welding power sources. As the heart of the inverter technology, the Insulated-Gate Bipolar Transistor (IGBT) module is responsible for high-speed switching of electrical power, converting the input supply into the precise welding output required for MIG, TIG, and Stick processes.

Using non-OEM or generic power modules in sophisticated inverter machines can lead to arc instability, thermal inefficiency, or catastrophic failure of the power board. This genuine ESAB part ensures that the electrical characteristics—such as switching frequency, voltage tolerance, and thermal dissipation—match the original engineering design of the Warrior machine. It is essential for maintaining the high duty cycle and rugged performance that the Warrior series is known for in heavy industrial fabrication environments.

This module set is intended for professional repair and maintenance of ESAB equipment. It restores the power source's ability to regulate current effectively, ensuring that the welder continues to deliver smooth, spatter-free starts and consistent penetration. When servicing high-voltage inverter equipment, relying on factory-specified components is the only way to guarantee safety and long-term operational integrity.
