K52249-25C - Lincoln Electric PTW-18 Water-Cooled TIG Torch, 500A, 25ft with Control Cable

High-Performance Water-Cooled TIG Welding

The Lincoln Electric PTW-18MLP-500 (K52249-25C) is a premium water-cooled TIG torch designed for professional fabricators and industrial welding environments requiring high-amperage performance. Engineered to handle the intense heat of heavy-duty TIG applications, this torch system ensures consistent conductivity and arc stability, allowing for precise welds on thick materials like aluminum and stainless steel.

Advanced Cooling and Capacity

Water-cooled technology is essential for welders operating at higher amperages for extended periods. The PTW-18MLP-500 is designated for high-output scenarios—indicated by its 500-amp nomenclature—providing superior cooling efficiency compared to air-cooled alternatives. This efficient heat dissipation protects the torch components from thermal damage and keeps the handle cool, significantly improving operator comfort during long duty cycles.

Integrated Control and Ergonomics

This assembly comes complete with a 25-foot cable, offering substantial reach to navigate around large workpieces or fixtures without repositioning the power source. A key feature of this specific configuration is the included control cable, which streamlines the connection to the welding machine, enabling arc initiation and amperage control (depending on the machine setup) directly from the torch assembly. The torch utilizes standard 18 Series (also known as 3 Series) consumables, ensuring that replacement collets, collet bodies, and gas lenses are readily available and easy to source.

Reliability for Industry

Lincoln Electric's Pro-Torch™ line is synonymous with durability. The cable materials are selected for their resistance to abrasion and heat, ensuring a long service life in shop environments. Whether you are welding pressure vessels, pipe, or heavy structural components, the PTW-18MLP-500 delivers the reliability required for critical code work.
