0558008052 - ESAB Replacement IGBT Module 200A 600V Dual Pack

Restore Your Welder's Performance

When your inverter welding machine goes down, production stops. The ESAB IGBT Dual Module (200A 600V) is a critical internal component designed to get your equipment back up and running at peak performance. This power module acts as the heart of your inverter's power supply, switching high currents at incredible speeds to create the stable, controllable arc you rely on. If your machine has lost output power or is displaying error codes related to the power stage, a failed IGBT is often the culprit.

Precision Engineering for Reliability

Manufactured to meet the exacting standards of ESAB equipment, this replacement part ensures that your machine operates exactly as the engineers intended. The module features a dual configuration, housing two Insulated Gate Bipolar Transistors in a single robust package. Rated for 200 Amps and 600 Volts, it is built to handle the rigorous electrical demands of industrial welding. Using genuine or high-specification replacement parts is vital for protecting the other sensitive electronics in your machine from voltage spikes or thermal runaway.

Symptoms of a Failing Power Module

Diagnosing a bad IGBT can be straightforward if you know what to look for. Common signs include a complete lack of arc despite the machine turning on, the breaker tripping immediately upon striking an arc, or the machine refusing to power up at all. In some cases, a catastrophic failure might even result in visible damage to the module itself. Replacing a faulty module with this 0558008052 unit can save you the cost of a completely new machine, extending the life of your existing investment significantly.

Installation and Care

Replacing an internal power component requires care. Ensure the machine is disconnected from all power sources and that internal capacitors have been discharged before servicing. Proper thermal management is key to the longevity of this new part; always ensure the heatsink surface is clean and apply a fresh layer of thermal compound during installation. This ensures that the heat generated during welding is efficiently transferred away from the module, preventing premature failure and keeping your welder running cool.
