330-1669 - Goss KA-2H Target Air-Acetylene Torch Kit with B-Tank Regulator

Technical Overview of the Goss KA-2H Air-Acetylene Kit

The Goss KA-2H is a professional-grade air-acetylene torch outfit designed for high-efficiency heating, soldering, and brazing applications. This kit is engineered around the Goss "Target" series technology, which utilizes a unique tip design to create a swirl combustion effect. This effect maximizes the mixture of acetylene and atmospheric air, resulting in a flame temperature and heat transfer rate significantly higher than conventional straight-bore tips. The kit is specifically configured for use with "B" style acetylene cylinders, featuring a CGA-520 regulator connection.

At the core of the system is the GH-4 handle, a robust brass torch handle designed for durability and ergonomic comfort during extended use. The handle features a needle valve for precise flame adjustment, allowing the operator to fine-tune the heat output for delicate soldering or aggressive brazing. The included GT-4 tip is a mid-range size suitable for a wide variety of copper tubing diameters, typically handling soft solder on pipes up to 2 inches and silver braze on pipes up to 1 inch. The tip's design ensures the flame wraps around the workpiece, ensuring even heat distribution.

The outfit includes an EA-1G regulator (or equivalent) that mounts directly to the B-tank valve. This regulator maintains a consistent flow of fuel gas to the torch, ensuring flame stability even as tank pressure fluctuates. Connecting the regulator to the handle is the AH-12 hose, a 12-foot flexible acetylene hose that meets industrial safety standards. The entire assembly is designed for portability and reliability, making it a staple tool for mechanical contractors, plumbers, and HVAC technicians requiring a mobile heat source without the bulk of an oxygen cylinder.
