94158044 - Arcair Sea Torch 3/16 Inch Collet Replacement

Technical Overview of the Arcair 94-158-044 Collet

The Arcair 94-158-044 is a specialized collet designed exclusively for use with the Arcair Sea Torch® combination torch (specifically model 14-050-124). This component plays a critical role in the electrical and mechanical assembly of the underwater torch, serving as the primary interface between the torch head and the consumable electrode. Engineered to accommodate 3/16-inch (4.8 mm) electrodes, this collet ensures precise concentricity and a high-pressure grip, which are essential for maintaining a stable arc in the challenging hyperbaric environment of underwater cutting and welding.

Manufactured from a high-grade copper alloy, the collet is optimized for thermal and electrical conductivity. In underwater applications, where resistance heating must be minimized to prevent equipment damage and ensure maximum energy transfer to the workpiece, the material composition of the 94-158-044 is paramount. The alloy also offers significant resistance to galvanic corrosion and oxidation, common issues in saline marine environments. The design features split jaws that compress uniformly around the electrode when the collet nut is tightened, preventing electrode slippage even under the mechanical stress of manipulation and water current drag.

Maintenance of the collet assembly is vital for the longevity of the Sea Torch. A worn or pitted collet can lead to arcing inside the torch head, potentially destroying the torch body. This replacement part meets strict OEM tolerances, ensuring it fits perfectly within the torch's insulation and gas flow channels. It is compatible with standard underwater welding electrodes and cutting rods of the specified diameter. Industrial MRO professionals and procurement specialists should verify the electrode diameter requirements of their specific diving operations before ordering, as the Sea Torch system utilizes different collets for varying electrode sizes.
