41202000 - Tweco Replacement Water Cooler Motor 1/3 HP 115/230V

Tweco 4120-2000 Replacement Motor for Water Coolers

The Tweco 4120-2000 is a high-quality replacement electric motor designed specifically for use in industrial welding water coolers and circulators. Engineered to meet the rigorous demands of continuous welding operations, this motor serves as the driving force behind the coolant pump, ensuring that liquid coolant is effectively circulated through TIG torches, MIG guns, and other water-cooled welding equipment. Maintaining proper coolant flow is critical for preventing equipment failure, extending consumable life, and ensuring operator comfort.

This unit features a power output of 1/3 Horsepower (HP), which provides ample torque to drive standard rotary vane pumps (such as Procon pumps) commonly found in welding cooling systems. The motor is versatile regarding power input, offering dual-voltage compatibility. It can be wired for either 110V-115V or 220V-230V single-phase power sources, making it adaptable to various shop electrical configurations. Additionally, it is rated for both 50Hz and 60Hz frequencies, allowing for international compatibility and stable operation regardless of local grid fluctuations.

As a genuine Tweco replacement part, the 4120-2000 ensures seamless integration with compatible Tweco water cooler models (such as the TC series). Using OEM parts guarantees that the mounting points, shaft dimensions, and electrical characteristics match the original equipment specifications, reducing downtime during repairs. The motor is built with industrial-grade components to withstand the heat and dust typical of fabrication environments. Proper installation of this motor restores the efficiency of the cooling system, protecting your valuable welding assets from thermal damage.

Technicians should verify the voltage setting on the motor prior to installation to match the input power of the water cooler unit. The motor housing is designed to dissipate heat effectively, and it typically features a standard NEMA carbonator mount or similar flange for direct coupling to the fluid pump. Whether you are refurbishing an older cooler or repairing a failed unit, the Tweco 4120-2000 provides the reliability and performance expected from a leader in welding technology.
