A-32 - Uniweld A-32 Air/Acetylene Swirl Combustion Tip

High-Efficiency Air/Acetylene Combustion Technology

The Uniweld A-32 Twister Tip represents a significant advancement in air/acetylene combustion technology, designed specifically for professional HVAC/R and plumbing applications. At the core of this component is Uniweld's proprietary helical blade technology. Unlike standard tips that produce a lazy flame, the A-32 forces the gas mixture through internal helical vanes, generating a high-velocity swirl. This turbulence ensures a more complete mixture of fuel and air, resulting in a flame that is both hotter and more stable. The intense spiral action wraps around copper tubing, maximizing surface area contact and dramatically increasing heat transfer efficiency. This allows technicians to reach target brazing temperatures faster, reducing gas consumption and labor time on the job site.

Engineered for versatility and performance, the A-32 is sized to handle a broad range of pipe diameters. It is rated for soft soldering copper tubing up to 2 inches (50mm) and silver brazing up to 1 inch (25mm). This makes it an ideal intermediate size for residential and light commercial installations. The tip is constructed with a quick-disconnect base, compatible with Uniweld's TH6 handles and other industry-standard quick-connect systems. This feature is critical for professionals who need to switch between tip sizes rapidly without the use of wrenches or tools. The robust construction ensures durability under high-heat conditions, maintaining the integrity of the flame pattern over prolonged use.

Operational stability is a key specification of the Twister series. The high-velocity flame is inherently resistant to blowout, making the A-32 particularly effective in outdoor environments or drafty workspaces where wind would typically disrupt the heating process. By maintaining a focused, high-energy flame, the tip ensures consistent capillary action during the brazing process, leading to leak-free joints and superior structural integrity in piping systems.
