K1784-4 - Lincoln Electric PTW-20 Pro-Torch TIG Torch - Water-Cooled, 250A, 25ft, 3-Piece Braided

Professional Grade Water-Cooled TIG Performance

The Lincoln Electric PTW-20 Pro-Torch™ TIG Torch (K1784-4) is a premium solution designed for fabrication shops, manufacturing environments, and heavy-duty pipe welding applications where thermal management and precision are paramount. Engineered to meet the rigorous demands of professional welders, this water-cooled torch system delivers a robust 250 Amps at 100% duty cycle, allowing for continuous operation without overheating or compromising weld quality. The water-cooling mechanism efficiently dissipates heat from the torch head, significantly extending the lifespan of consumables and ensuring the handle remains cool to the touch even during prolonged high-amperage arcs.

Durability and Engineering

At the core of the K1784-4 is its high-quality construction. The torch features a 25-foot 3-piece braided rubber cable assembly. Unlike standard vinyl cables, the braided rubber design offers superior resistance to heat, abrasion, and kinking, making it ideal for dynamic industrial environments. This cable configuration ensures consistent current delivery and shielding gas flow, which are critical for achieving X-ray quality welds. The torch body itself is manufactured from high-grade materials to resist impact and thermal stress, embodying the reliability that Lincoln Electric is known for in the welding industry.

Ergonomics and Control

Operator comfort is directly tied to weld precision. The PTW-20 is equipped with a comfortable knurled handle that provides a secure, non-slip grip. This tactile surface allows welders to maintain precise control over the torch angle and travel speed, even when wearing heavy welding gloves. Additionally, the handle features a specially molded lip and ridge designed to anchor zippered cable covers securely. This thoughtful design element prevents the cable cover from sliding down, keeping the hoses protected and the workspace organized. Whether you are welding stainless steel, aluminum, or mild steel, the PTW-20 offers the stability and performance required for critical tasks.
