K52261-25 - Lincoln PTW-18M Water-Cooled Machine TIG Torch 500A 25ft

Heavy-Duty Mechanized TIG Welding Solution

The Lincoln Electric PTW-18M-500 Mechanized TIG Torch (K52261-25) is a premium industrial tool designed for high-precision automated welding environments. Engineered to handle the rigors of continuous operation, this torch features a robust water-cooling system that enables a 100% duty cycle at 500 amps. This makes it an exceptional choice for fabrication shops and manufacturing facilities requiring consistent, high-amperage welds on thick materials such as aluminum and stainless steel. The torch is built around the industry-standard 18-series platform, ensuring that replacement parts and consumables are readily available and cost-effective.

This model is specifically configured with a straight machine barrel, allowing for secure mounting in fixtures, bug-o systems, or other automated carriages. The 25-foot cable assembly provides significant reach, accommodating large workpieces and flexible machine positioning. The inclusion of the Twist Mate connector simplifies the setup process, allowing operators to connect the torch to compatible Lincoln Electric power sources without the need for tools, ensuring a solid electrical connection and optimal gas flow.

Durability is a key focus of the PTW-18M-500. The cable assembly is encased in a protective cover that shields the power cable and water hoses from the harsh industrial environment, including exposure to heat, sparks, and abrasion. Whether used in pipe welding automation, seam welders, or custom robotic cells, this torch delivers the reliability and performance expected from Lincoln Electric products.
