K4713-1 - Lincoln Electric Cool Wave 20S High-Capacity Water Cooler 115V

High-Performance Cooling for Industrial Welding

The Lincoln Electric Cool Wave™ 20S Water Cooler (K4713-1) is a precision-engineered thermal management system designed to support high-amperage welding operations. Built specifically for compatibility with Lincoln's advanced Power Wave® S-Series and R-Series power sources, this unit ensures consistent operating temperatures for water-cooled torches in heavy fabrication and robotic environments. With a robust cooling capacity of 6,824 BTU/hr (2.00 kW) at 1 L/min, the Cool Wave 20S effectively manages heat dissipation for torches rated up to 600 amps at 100% duty cycle, enabling continuous production without thermal throttling.

Technologically advanced, the Cool Wave 20S features a suite of smart sensors that actively monitor critical system parameters, including coolant flow rate, reservoir capacity, and fluid temperature. This intelligent feedback loop communicates directly with the power source via Digital/Arclink connections. In the event of a flow restriction, low coolant level, or temperature spike, the system automatically halts the welding process. This proactive safety mechanism prevents catastrophic failure of expensive torch consumables and power cables, significantly reducing maintenance costs and unplanned downtime.

Operational efficiency is further enhanced by the unit's automatic hibernation capability. When the welding arc is idle, the cooler enters a low-power standby mode, reducing energy consumption and minimizing mechanical wear on the pump and internal components. The unit features a substantial 2.375-gallon (9-liter) reservoir, minimizing the frequency of coolant refills. Operating on standard 115 VAC single-phase power, the Cool Wave 20S offers a seamless, plug-and-play solution for upgrading the thermal capacity of your Lincoln Electric welding cell.
