14050126 - Arcair Sea Torch Combination Underwater Torch with 3/8" Collet

Technical Overview: Arcair Sea Torch (14-050-126)

The Arcair Sea Torch is a definitive solution for underwater industrial applications, specifically engineered for the rigors of offshore salvage, maintenance, and construction. This specific model, SKU 14-050-126, is pre-configured with a 3/8-inch collet chuck, optimizing it for standard 3/8-inch diameter underwater electrodes used in both exothermic cutting and wet welding processes. The torch represents a significant evolution in diver safety and tool durability, utilizing a one-piece body construction.

Unlike multi-part torches that rely on gaskets and seals which can degrade under high pressure or saline exposure, the Sea Torch's body is molded from a high-impact, non-conductive composite material. This design choice eliminates body seams, thereby removing the most common leak paths found in inferior equipment. The material also provides complete electrical insulation, a critical specification for preventing electrolysis and ensuring the safety of the diver-welder during live current operations. The internal components are designed to manage the flow of oxygen for exothermic cutting efficiently, with a valve mechanism that seals positively to prevent gas leakage when not in use.

The 3/8-inch collet system is robust, designed to grip the electrode firmly to ensure consistent electrical contact and prevent rod slippage during the manipulation required in underwater environments. The torch assembly includes a spark arrestor located behind the collet nut, which serves as a vital safety barrier against flashbacks. Maintenance of the Sea Torch is streamlined; the design allows for rapid disassembly and cleaning of the collet and oxygen valve assembly without requiring specialized tooling, minimizing downtime on the barge or dive station.
