35815 - ESAB 35815 Replacement Contactor Assembly

Technical Overview of the ESAB 35815 Plate Contactor

The ESAB 35815 Plate Contactor is a specialized electrical replacement component designed for specific ESAB welding power sources and wire feeding systems. As a critical element of the machine's internal circuitry, the contactor serves as the primary switch for the high-current welding output. When the torch trigger is pulled, this contactor engages to allow current to flow to the electrode; when released, it disengages to cut the arc. This specific SKU, 35815, refers to the plate-mounted assembly, ensuring that the contactor is securely oriented within the machine chassis to withstand the mechanical vibrations and thermal stresses typical of industrial environments.

Using genuine OEM parts like the ESAB 35815 is essential for maintaining the safety and certification of welding equipment. Aftermarket or ill-fitting electrical components can lead to increased resistance, overheating, or arc failure. This unit is manufactured to ESAB's precise engineering standards, ensuring that the coil voltage, contact rating, and physical mounting points align perfectly with the original equipment specifications. It is intended for professional repair technicians performing maintenance on ESAB welding systems that require this specific part number for the power control assembly.

Failure of a contactor can manifest as a machine that will not arc, a machine that arcs continuously (stuck contacts), or intermittent power delivery. Replacing the faulty unit with the ESAB 35815 restores the machine to full operational status. Please verify this part number against your machine's service manual or parts diagram before installation to ensure compatibility with your specific model year and series.
