36349 - ESAB ESP-200 Replacement Auto Transformer

Technical Overview of the ESAB 36349 XFMR Auto Transformer

The ESAB 36349 is a specialized Auto Transformer (XFMR) engineered specifically for the power regulation and voltage transformation needs of the ESAB EPP and ESP-200 plasma cutting systems. As a critical component within the power source architecture, this transformer manages the voltage levels required to sustain the high-energy plasma arc used in heavy industrial cutting. Failure of the main or auto-transformer in these units can lead to inconsistent arc initiation, inability to reach full amperage, or complete system power failure.

This OEM part is manufactured to ESAB's precise specifications, ensuring that the electrical impedance, turn ratio, and thermal dissipation characteristics match the original design of the ESP-200. The unit features robust core laminations designed to minimize eddy current losses and reduce heat buildup during extended operation. The windings are insulated with high-grade varnish to withstand the thermal stresses and vibration common in industrial environments. Proper installation of this transformer is essential for restoring the machine's ability to regulate input power effectively.

Technicians servicing EPP-200 or ESP-200 units should verify that the failure of the previous component was not caused by downstream shorts or upstream voltage spikes before installation. The 36349 connects directly into the existing wiring harness of the power source, utilizing standard ESAB color-coding and terminal types for a straightforward replacement process. By using this genuine part, maintenance teams ensure compliance with the machine's original safety and performance standards.
