57N47 - Weldcraft 57N47 3/32" (2.4mm) TIG Collet for WP-27 Torches (2-Pack)

Product Overview

The Weldcraft 57N47 Collet is a specialized TIG welding consumable designed for the heavy-duty WP-27 series torches. Manufactured by Miller Weldcraft, this component plays a critical role in the electrical and mechanical assembly of the torch head. It is engineered to securely hold a 3/32-inch (2.4mm) tungsten electrode, ensuring precise alignment and consistent current transfer during high-amperage welding operations. The 57N47 is specifically compatible with WP-27A and WP-27B torch models, which are typically utilized in demanding industrial environments requiring robust equipment.

Constructed from high-grade copper alloy, the collet is designed to withstand the thermal stresses associated with heavy-duty TIG welding. Its primary function is to clamp the tungsten electrode against the collet body when the back cap is tightened, creating the necessary electrical contact for arc initiation and stability. Proper maintenance of this component is essential; a worn or deformed collet can lead to poor arc starts, unstable arcs, and overheating of the torch head due to increased electrical resistance.

This product is supplied in a pack of two, providing distributors and end-users with necessary stock for routine maintenance intervals. As a genuine Weldcraft part, it guarantees dimensional accuracy and material quality that meets the original equipment manufacturer (OEM) specifications for the WP-27 series. It is distinct from the standard 10N series collets used in smaller torches (WP-17/18/26) and the 13N series used in WP-9/20 torches, featuring a larger physical profile to accommodate the heavy-duty nature of the WP-27 system.

Technical Specifications

The 57N47 features a standard 3/32" bore diameter. It is critical to match the collet size to the tungsten electrode diameter to prevent arcing inside the collet body or slippage of the electrode. This component is part of the essential consumable stack for the WP-27, sitting between the torch body and the collet body. Regular inspection for twisting, burning, or elongation is recommended to maintain system integrity.
