OVERVIEW

Reliable Cooling for Your Welding Operations

The Tweco 4120-2004 Gear Pump is a critical replacement component designed to restore the functionality of your welding water cooler. In high-amperage TIG and MIG welding applications, maintaining proper torch temperature is essential not only for consumable life but also for the safety and comfort of the welder. When your water cooler's pump fails, coolant circulation stops, leading to rapid overheating and potential equipment failure. This genuine Tweco gear pump is engineered to exact specifications, ensuring it fits perfectly into compatible Tweco and Thermal Arc water cooling units.

Built for durability, this rotary gear pump provides the steady pressure and flow rate required to circulate coolant through long torch leads and tight cooling passages. Whether you are operating in a heavy industrial fabrication shop or a precision aerospace facility, relying on OEM-quality parts like the 4120-2004 ensures your equipment performs as intended. Installation is straightforward for maintenance personnel, allowing you to minimize downtime and get your welding station back up and running quickly.

At Josef Gas, we understand that equipment reliability is key to your business. That's why we stock essential repair parts like this gear pump. Don't let a failed pump halt your production; replace it with a high-quality unit designed to withstand the rigors of daily industrial use. This pump is compatible with specific models of water coolers often paired with high-performance power sources.

FAQ

Its primary function is to circulate coolant from the water cooler reservoir through the welding torch and back, preventing the torch from overheating during welding.

Signs include a lack of coolant flow at the torch, the torch becoming unusually hot, unusual noises coming from the cooler, or visible leaks around the pump housing.

No, it is specifically designed for certain Tweco and Thermal Arc water cooler models. Please check your equipment's parts manual or contact support to verify compatibility.

Yes, if you have basic mechanical skills and knowledge of the equipment. However, always disconnect power before servicing and follow the manufacturer's installation guidelines.

Typically, the pump is sold as the unit itself. You may need to transfer existing fittings from your old pump or purchase new ones separately if they are damaged.

You should use a coolant specifically designed for welding applications, such as low-conductivity mixtures that prevent corrosion and algae growth. Avoid automotive antifreeze.

Yes, this is a genuine Tweco replacement part, ensuring it meets the original specifications for performance and fitment.

Gear pumps are positive displacement pumps that provide a constant flow rate and are capable of generating the higher pressures needed to push coolant through long, narrow torch cables.
