K52249-25 - Lincoln PTW-18 Water-Cooled TIG Torch 350A 25ft

Heavy-Duty Water-Cooled Performance

The Lincoln Electric PTW-18 TIG Torch (K52249-25) is a premium water-cooled welding torch designed for professional fabricators who demand reliability and high performance. Rated at 350 Amps at 100% duty cycle, this torch is engineered to handle the most demanding industrial applications without overheating, ensuring consistent weld quality and prolonged consumable life.

Robust Construction & Comfort

Built with the welder in mind, the PTW-18 features a rugged yet lightweight design. The handle is ergonomically shaped to provide a secure grip and minimize hand fatigue during extended welding sessions. The high-quality copper components within the torch head ensure maximum electrical conductivity and efficient heat dissipation, which is critical when welding thick materials or running long beads at high amperages.

Versatile Compatibility

This model comes with a 25-foot (7.6 meter) 3-piece cable assembly, offering excellent reach and flexibility around large workpieces. As an 18-series torch, it is compatible with a wide range of industry-standard front-end consumables (collets, collet bodies, gas lenses, and nozzles), making it easy to source replacement parts and tailor the torch setup to your specific welding needs. Whether you are welding aluminum, stainless steel, or mild steel, the PTW-18 delivers the precision and power required for top-tier results.

Key Applications

Ideal for heavy fabrication, aerospace, automotive manufacturing, and pipe welding, the Lincoln PTW-18 integrates seamlessly with Lincoln Electric power sources (requires appropriate adapter) and water coolers. Its water-cooled architecture allows for a smaller torch head profile relative to its amperage capability compared to air-cooled equivalents, providing better access to tight spaces while maintaining high power output.
