K1859-1 - Lincoln Electric 25ft Water Cooler Hose Kit (CGA to QD)

Technical Overview of the Lincoln Electric K1859-1

The Lincoln Electric K1859-1 is a specialized Water Cooler Hose Kit designed to establish a reliable fluid transfer loop between a welding water cooler and a compatible wire feeder. This kit is engineered to meet the specific connection requirements of the Lincoln Electric Cool Arc 40 and similar cooling units. The assembly consists of two individual hoses, each measuring 25 feet in length, providing substantial reach to accommodate various shop layouts and equipment configurations. This extended length is particularly beneficial in industrial settings where the power source and cooler may need to be positioned at a distance from the wire feeder and welding operator.

A critical feature of the K1859-1 is its fitting configuration. On the cooler side, the hoses are terminated with 5/8-inch Left Hand CGA fittings. The use of left-hand threads is a standard safety protocol in the welding industry to prevent the accidental connection of water lines to gas regulators or outlets, thereby mitigating the risk of equipment damage or contamination. On the feeder end, the hoses are equipped with Male Quick Disconnect (QD) fittings. These connectors are designed to mate seamlessly with wire feeders that possess corresponding female disconnects, facilitating rapid assembly and disassembly of the welding station without the need for tools.

The hoses themselves are constructed from durable materials capable of withstanding the pressures and environmental conditions typical of heavy-duty welding operations. Proper maintenance of coolant lines is essential for the longevity of water-cooled torches; the K1859-1 ensures that coolant flow remains consistent and leak-free. By utilizing genuine Lincoln Electric parts, operators ensure full compatibility with the Cool Arc series, maintaining the integrity of the cooling system's pressure and flow rates. This kit is an essential component for MRO professionals maintaining Lincoln Electric MIG/MAG systems requiring active water cooling.
