0465427880 - ESAB Cool 2 Water Cooler for Caddy and Origo Tig Machines

Technical Overview of the ESAB Cool 2 Cooling Unit

The ESAB Cool 2 Cooling Unit (SKU: 0465427880) is a specialized water-cooling accessory engineered to enhance the duty cycle and performance of compatible ESAB welding power sources. Specifically designed for integration with the Caddy Tig 2200i AC/DC, Caddy Tig 2200i DC, and Origo Tig 3000i series, this unit provides essential thermal management for water-cooled TIG torches and MIG guns. By maintaining optimal operating temperatures, the Cool 2 ensures consistent electrical conductivity and prevents the degradation of torch components during high-amperage or prolonged welding operations.

Technically, the Cool 2 features a robust cooling capacity of approximately 1000 watts at an ambient temperature of 40°C, which is sufficient to handle the heat load generated by standard industrial welding tasks. The system utilizes a magnetically coupled centrifugal pump. This design choice is critical for industrial reliability as it eliminates the need for dynamic shaft seals, which are common failure points in standard pumps, thereby significantly reducing the risk of coolant leakage and pump failure. The unit circulates coolant at a maximum flow rate of 2 liters per minute with a maximum pressure of 2.3 bar, ensuring rapid heat exchange at the torch head.

The reservoir has a capacity of 2.2 liters, balancing a compact footprint with sufficient thermal mass to prevent rapid coolant saturation. The unit is powered directly via a 24V DC connection from the host welding machine, simplifying the setup by removing the need for an auxiliary mains power cable. The physical construction involves a durable chassis that mounts securely beneath the power source, creating a unified, portable welding station. This integration is vital for mobile industrial applications where equipment footprint and ease of transport are logistical priorities.

Maintenance and operation are streamlined through a clear coolant level indicator and an easily accessible filling port. The system is designed to circulate a mixture of water and propylene glycol (ESAB recommended coolant) to prevent freezing and corrosion within the torch lines and the heat exchanger itself. For MRO professionals and welding engineers, the ESAB Cool 2 represents a reliable, OEM-validated solution for upgrading air-cooled systems to water-cooled configurations, thereby unlocking higher amperage capabilities and extended duty cycles for their existing ESAB fleets.
