951477 - Thermal Arc WC-7C Replacement Coolant Pump

Restore Optimal Cooling Performance with the WC-7C Pump

The ESAB (Thermal Arc) Coolant Pump 951477 is a critical replacement component designed specifically for the WC-7C Water Cooler system. In high-precision TIG welding applications, the stability of the cooling system is paramount. This pump serves as the heart of the coolant loop, generating the necessary pressure and flow rate to circulate cooling fluid from the reservoir through the torch head and back. A failing pump can lead to immediate thermal runaway in the torch, compromising both the equipment and the weld integrity.

Engineered to OEM specifications, this pump ensures a seamless integration with the existing WC-7C assembly. It features a robust internal mechanism capable of handling the continuous duty cycles often required in industrial fabrication environments. The pump is constructed to resist the corrosive nature of standard welding coolants, ensuring longevity and consistent output over time. Unlike generic aftermarket pumps that may require modification or adapters, this genuine part guarantees correct port alignment and mounting dimensions, significantly reducing maintenance downtime.

Technicians and maintenance personnel will appreciate the direct-fit nature of this component. When a water cooler exhibits symptoms such as reduced flow alarms, excessive noise, or complete circulation failure, the pump is often the primary suspect. Replacing the unit with the correct 951477 part restores the system to factory operating parameters. This proactive maintenance step protects the more expensive components of the welding cell, such as the high-amperage TIG torch and power cable assembly, from heat-induced failure.

By maintaining the proper flow rate, this pump aids in efficient heat dissipation, allowing the welding power source and torch to operate at their rated duty cycles. Whether for a single repair or as a strategic spare for critical production lines, the WC-7C Coolant Pump is an essential investment in equipment reliability.
