Arcair 94-158-043 5/16" Collet Chuck for Sea Torch

The Arcair 94-158-043 is a precision-engineered 5/16" Collet Chuck designed exclusively for the Arcair Sea Torch, the industry standard for underwater combination cutting and welding torches. In the demanding environment of underwater salvage, construction, and maintenance, the reliability of every component in the torch assembly is paramount. This collet chuck serves as the critical interface between the torch body and the electrode, ensuring that the cutting or welding rod is held firmly in place against the mechanical forces of drag and manipulation by the diver.

Manufactured to Arcair's exacting standards, this collet chuck is crafted from high-grade conductive alloys capable of withstanding the corrosive nature of saltwater environments while maintaining excellent electrical transfer properties. A loose or worn collet can lead to arcing inside the torch head, poor arc stability, and potential damage to the torch body itself. By replacing worn collets with genuine Arcair parts, operators ensure maximum efficiency during exothermic cutting or wet welding procedures. The 5/16" size is a standard configuration for many underwater applications, providing the versatility needed for various material thicknesses.

Proper maintenance of the Sea Torch involves regular inspection of the collet chuck. Over time, the constant cycle of heating, cooling, and mechanical tightening can wear down the internal gripping surface. This replacement part (94-158-043) restores the torch to factory specifications, allowing for quick electrode changes and consistent current flow. Whether used for severing steel piles, cutting chain, or welding patches on a hull, this collet chuck provides the secure grip necessary for precise control. It is an essential spare part for any commercial diving operation utilizing the Arcair Sea Torch system.

Integration with the Sea Torch design allows for seamless installation. The collet fits snugly within the torch head assembly, working in conjunction with the collet nut to compress around the electrode. This design minimizes resistance and heat buildup at the connection point, directing the energy where it is needed most—at the arc. Trust in genuine Arcair components to deliver the safety and performance required in the hazardous underwater environment.
