94158047 - Arcair 1/8 Inch Collet for Sea-Torch Underwater System

Reliable Grip for Your Sea-Torch

When you are working underwater, equipment failure is not just an inconvenience—it is a safety hazard and a massive cost in bottom time. The Arcair 94-158-047 1/8" Collet is the genuine replacement part you need to keep your Arcair Sea-Torch operating at peak performance. Designed specifically for the Sea-Torch combination cutting and welding torch, this collet ensures that your 1/8-inch electrodes are gripped securely, allowing you to focus on the weld or cut without worrying about your consumable slipping or losing contact.

Over time, collets can wear down from the heat and friction of repeated electrode changes and high-amperage current transfer. A worn collet can cause unstable arcs, overheating of the torch head, and frustrating electrode wobble. Swapping in a fresh 94-158-047 collet restores the tight mechanical connection needed for precise control. This is particularly important in underwater environments where visibility and stability are already challenging; having a torch that responds predictably to your movements is essential for producing quality wet welds or clean cuts.

This collet is built to withstand the harsh marine environment. It resists corrosion from saltwater and maintains its shape even under thermal stress. It is designed for quick change-outs, allowing topside tenders or divers to switch configurations or replace worn parts efficiently. If your job requires 1/8" cutting rods or welding electrodes, this is the specific internal component required to seat them properly in the Sea-Torch head.

Don't compromise your setup with ill-fitting generic parts. The Arcair Sea-Torch is an industry standard for a reason, and using genuine Arcair parts like the 94-158-047 collet ensures you maintain that standard. Keep a few of these in your spares kit to ensure that a worn part never halts a dive operation. It provides the confidence that when you pull the trigger, the power will be there, and the rod will stay put.
