Lincoln Electric K1784-3 Tig Welding Torch 250A Water Cooled

Product Description

The LINCOLN ELECTRIC K1784-3 is a water-cooled TIG welding torch rated at 250 amps, designed for high-heat applications where air-cooled torches fall short. Water cooling circulates coolant through the torch body and cable to dissipate heat generated during sustained high-amperage TIG welding. The rigid head is fixed at a 70-degree angle, providing consistent torch positioning for flat, horizontal, and overhead welds. The cable assembly measures 12.5 feet, giving the welder adequate reach from the power source to the workpiece without excess cable drag. This torch is installed and used by certified welders and welding fabricators in production, maintenance, and repair environments.

The K1784-3 is suited for industrial and heavy fabrication applications where continuous or high-duty-cycle TIG welding is performed on carbon steel, stainless steel, aluminum, and other metals. The water-cooled design keeps the torch handle cooler during long weld passes, reducing operator fatigue and protecting torch components from heat damage. The rigid 70-degree head angle is a standard configuration commonly used in shop and field fabrication. The 12.5-foot cable length is appropriate for bench welding stations and automated or semi-automated setups where the power source is positioned nearby.

Key Features

• Water-cooled torch body rated for 250 amps sustained output
• Rigid head fixed at 70-degree angle for consistent torch positioning
• 12.5-foot cable length for practical reach from power source to work
• Water cooling extends component life and reduces handle heat during high-duty-cycle operation
• Designed for professional welding environments requiring sustained high-amperage TIG output

Compatibility

Designed as an OEM-style water-cooled TIG torch replacement for Lincoln Electric-compatible TIG welding systems requiring a 250-amp water-cooled torch with a rigid head. Verify coolant fitting type and power connector compatibility with your specific power source before installation.

Installation Notes

Installation and connection of TIG welding torches should be performed by a qualified welder or welding equipment technician. Power down and disconnect the welding power source before attaching or removing the torch. Ensure the water cooler unit is shut off and pressure is relieved from the coolant lines before disconnecting coolant hoses. Follow the power source and water cooler manufacturer guidelines for proper hose routing, fitting torque, and electrical connection to avoid leaks or arc faults during operation.
