NCB-36 - Weldcraft NCB-36 Heavy Duty Collet Body for 18SC Torch (5-Pack)

Precision Engineering for High-Amperage TIG Welding

The Weldcraft NCB-36 Heavy Duty Collet Body is a specialized consumable designed exclusively for the 18SC (Super Cool) series of TIG torches. In the realm of industrial welding, where high amperage and duty cycles are the norm, the integrity of the torch's front-end consumables is paramount. This collet body is engineered to facilitate the transfer of welding current from the torch body to the tungsten electrode with minimal resistance, ensuring a stable and focused arc even under demanding conditions.

Accommodating tungsten electrode diameters ranging from 1/8 inch (3.2mm) to 3/16 inch (4.8mm), the NCB-36 is versatile enough to handle heavy fabrication tasks requiring deep penetration and substantial heat input. The heavy-duty designation indicates a robust construction capable of withstanding the intense thermal cycling associated with water-cooled, high-current applications. Unlike standard collet bodies, the NCB-36 features enhanced mass and superior conductive materials to aid in heat dissipation, thereby prolonging the life of both the collet and the torch head.

Using genuine Weldcraft (Miller) parts guarantees dimensional accuracy and thread compatibility. A poor fit in the collet body can lead to gas turbulence, poor shielding coverage, and arcing within the torch threads—issues that can ruin a weld and damage expensive torch components. The NCB-36 ensures a tight, concentric fit for the tungsten, promoting laminar gas flow and precise electrode alignment. This pack contains five units, providing facility managers and welding engineers with necessary inventory to maintain continuous operations without interruption.
