K3475-1 - Cool Arc 22 Water Cooler for Aspect 230

Advanced Cooling for Precision TIG Welding

The Lincoln Electric Cool Arc 22 (K3475-1) is a specialized cooling system engineered exclusively for the Aspect 230 AC/DC and DC TIG welder series. Designed to meet the rigorous demands of industrial fabrication, this unit ensures that water-cooled TIG torches operate within their optimal temperature ranges, thereby extending consumable life and maintaining consistent arc performance during extended duty cycles. The system features a robust pump capable of generating a maximum pressure of 62 PSIG, delivering a cooling power of 0.87 kW at a flow rate of 1 L/min (measured at 77°F). This thermal management capability is essential for preventing equipment overheating in high-amperage applications.

Integration is a key design philosophy of the Cool Arc 22. The unit is constructed to mount directly underneath the Aspect 230 power source, creating a unified, vertical footprint that saves valuable floor space. It is specifically compatible with the Aspect 230 two-wheeled cart (K4441-1), ensuring a secure and mobile welding station. Unlike generic coolers that require separate 115V or 230V wall power, the Cool Arc 22 is powered directly by the welder itself via a 390V DC input, simplifying cable management and reducing setup time in dynamic shop environments.

Operational safety and equipment protection are enhanced through intelligent flow monitoring. The Cool Arc 22 is equipped with a coolant flow detector that communicates directly with the power source. If coolant flow is interrupted or falls below safe levels, the system triggers a safety protocol to prevent the TIG torch from overheating, potentially saving operators from costly torch failures. Maintenance and setup are further streamlined by the inclusion of Quick Connect/Disconnect fluid fittings, allowing for rapid torch changes without the need for tools or complex plumbing adjustments. The reservoir holds 0.6 gallons of coolant, balancing capacity with portability.

For optimal performance and system longevity, Lincoln Electric recommends the use of their Low Conductivity Coolant (KP4159-1). This specific formulation helps prevent galvanic corrosion and electrical bridging within the torch head, ensuring the system remains reliable over years of service. The Cool Arc 22 represents a purpose-built solution for professionals utilizing the Aspect 230 platform, delivering efficiency, protection, and seamless integration.
