A-14 - Uniweld A-14 Twister Air/Acetylene Tip with Quick Disconnect

High-Efficiency Combustion Technology

The Uniweld A-14 Twister Tip represents a significant advancement in air/acetylene combustion technology tailored for the HVAC/R and plumbing industries. At the core of this component is Uniweld's proprietary Twister® helical blade technology. Unlike standard tips that produce a lazy or direct flame, the A-14 forces the gas mixture through a spiral channel, creating a high-velocity swirl. This action maximizes the mixing of fuel gas and air, resulting in a flame that is not only hotter but also more stable. The increased turbulence ensures complete combustion, maximizing BTU output and reducing fuel waste.

Operational Stability in Adverse Conditions

One of the primary challenges in field brazing is maintaining a consistent flame temperature in outdoor environments. The A-14 is specifically engineered to resist flame blowout in windy conditions, a common issue on rooftops or drafty construction sites. The high-velocity swirl creates a rigid flame structure that maintains its integrity against air currents. Furthermore, the flame's characteristic "wrap-around" effect allows it to encompass the copper tubing, delivering heat to the back side of the pipe without requiring the operator to constantly reposition the torch handle. This feature significantly speeds up the heating process and ensures uniform penetration of the filler metal.

Quick Disconnect System

Efficiency in the field is also defined by the speed of setup and breakdown. The A-14 features a Quick Disconnect coupling mechanism. This allows the technician to swap between different tip sizes instantly without the need for wrenches or tools. Whether moving from a small capillary tube to a large suction line, the operator can change the tip in seconds, ensuring the right heat output is always applied to the specific pipe diameter. This system reduces downtime and wear on threaded components.
