KP2031-1B1 - Lincoln Electric 13N25 TIG Collet Body .020" (5-Pack)

Precision TIG Welding with Lincoln Electric KP2031-1B1

When it comes to precision TIG welding, especially when utilizing ultra-fine tungsten electrodes like the .020" (0.5 mm) size, the quality of your consumables is paramount. The Lincoln Electric KP2031-1B1 Collet Body is engineered to meet the rigorous demands of professional welders who require stability and accuracy in their arc. This collet body is designed to securely hold the collet and tungsten electrode in place within the torch head, ensuring optimal current transfer and heat dissipation during the welding process.

This specific model corresponds to the industry-standard 13N25 part number, making it a versatile choice for a wide range of TIG torches. It is fully compatible with standard 9 series air-cooled torches and 20 series water-cooled torches, including Lincoln's own PTA-9, PTA-20, and PTW-25 models. By using genuine Lincoln Electric parts, you ensure that your equipment operates at peak efficiency, reducing the risk of arc wandering or poor starts that can occur with inferior generic consumables.

The .020" size is typically reserved for very delicate applications, such as micro-welding, electronics repair, or thin-gauge sheet metal work where heat input must be strictly controlled. In these scenarios, the mechanical fit of the collet body is critical. The KP2031-1B1 provides a tight, concentric fit that aligns the tungsten perfectly with the gas cup, promoting smooth gas coverage and a focused arc. This 5-pack ensures you have replacements on hand, minimizing downtime in your shop.
