0460144880 - ESAB CoolMini Water Cooler for Caddy Tig 2200i

Technical Overview of the ESAB CoolMini

The ESAB CoolMini (SKU: 0460144880) is a specialized cooling unit engineered exclusively for the ESAB Caddy Tig 2200i and Caddy Tig 2200i AC/DC welding power sources. This unit is critical for setups requiring water-cooled TIG torches, enabling the system to operate at higher amperages and extended duty cycles without thermal overload of the torch components. The device is designed to dock seamlessly beneath the power source, maintaining the compact footprint characteristic of the Caddy line.

Technically, the CoolMini utilizes a convection cooling mechanism with a cooling capacity of approximately 700 Watts at a temperature differential of 40°C. It features a coolant reservoir with a capacity of 2.2 liters, which is sufficient for the portable nature of the equipment. The pump delivers a maximum water flow of 2 liters per minute with a maximum pressure of 2.3 bar, ensuring adequate circulation through standard water-cooled TIG torches. The unit draws its power directly from the welding machine via a dedicated connection interface, eliminating the need for a separate mains power cable.

Construction-wise, the chassis is robust yet lightweight, weighing only 6.7 kg when empty. This ensures that the combined weight of the welder and cooler remains manageable for mobile applications. The integration logic of the Caddy Tig system allows the cooler to activate only when necessary or upon arc initiation, contributing to energy efficiency and reduced noise levels during standby. This accessory is essential for industrial MRO applications where aluminum welding (AC TIG) or heavy-duty DC TIG welding is performed using portable equipment.
