22K39 - Miller Weldcraft WP-17-12-R Air-Cooled TIG Torch, 150A, 12ft

Industry-Standard 150A Air-Cooled TIG Torch

The Miller Weldcraft WP-17-12-R (SKU: 22K39) represents the industry standard for general-purpose, air-cooled TIG welding. Designed for versatility and reliability, this torch belongs to the renowned WP-17 series (often referred to as the A-150 series in modern Weldcraft nomenclature), which is widely recognized for its robust construction and ease of use. It is engineered to handle a wide range of welding applications, from light industrial fabrication to maintenance and repair operations, offering a maximum output of 150 Amps DC and 115 Amps AC at a 60% duty cycle.

This specific model features a 12-foot, one-piece rubber power cable. The use of rubber over vinyl provides superior resistance to heat, abrasion, and kinking, ensuring the cable remains flexible even in colder environments or during extended use. The one-piece cable design simplifies connection to power sources, typically requiring a standard power cable adapter (such as the 45V11, often associated with SKU 37Z23) to connect to the output stud of the welding machine. The torch body is constructed from high-grade copper components to maximize current transfer and minimize heat buildup in the handle, prolonging the life of the torch and consumables.

The WP-17-12-R is compatible with standard 10N series consumables (collets, collet bodies, and ceramic cups), making replacement parts easy to source and affordable. The handle features a ribbed diamond pattern that promotes a secure grip and helps dissipate heat, reducing operator fatigue during long welding sessions. Whether you are welding mild steel, stainless steel, or aluminum, this torch provides the control and consistency required for high-quality TIG welds. It is an excellent choice for welders who need a reliable, portable solution without the bulk and expense of a water-cooled system.
