89620 - Uniweld Twister Air-Acetylene Torch Kit with TH-6B Handle & A-5 Tip

Technical Overview of the Uniweld 89620 Twister Kit

The Uniweld 89620 is a comprehensive Air-Acetylene outfit designed for professional plumbing and HVAC applications. This kit is engineered around Uniweld's proprietary Twister® technology, which utilizes a helical blade inside the tip to create a high-velocity swirl combustion flame. This design ensures maximum heat transfer and flame stability, making it highly effective for soldering and brazing copper tubing.

The core components of this kit include the TH-6B Quick Connect Handle and the A-5 Twister Tip. The Quick Connect mechanism is a critical technical feature, allowing operators to snap tips in and out of the handle without the need for wrenches, thereby reducing downtime during tip changes. The handle is ergonomically designed with a rear control valve for precise gas flow adjustment.

Gas regulation is managed by an RB-series regulator fitted with a CGA 520 inlet, specifically machined for "B" size acetylene cylinders (40 cu. ft.). The regulator is equipped with protective rubber gauge boots to shield the gauges from impact damage, a common occurrence in field service environments. The kit also includes a specialized acetylene hose fitted with Quick Connect fittings to match the handle assembly, ensuring a secure and leak-proof gas delivery system. A tank key with a security chain is provided to ensure the cylinder valve can be operated safely and that the tool remains with the kit.
