A-3 - Uniweld A-3 Quick Connect Air/Acetylene Swirl Tip

Uniweld A-3 Twister Tip: Precision Engineering for HVAC and Plumbing

The Uniweld A-3 Twister Tip represents a significant advancement in air/acetylene combustion technology, designed specifically for professional contractors who demand efficiency and reliability. At the core of this component is Uniweld's patented helical blade technology. Unlike standard tips that produce a feather flame, the Twister Tip forces the gas mixture into a high-velocity swirl. This vortex action maximizes the mixing of fuel gas and air, resulting in a combustion efficiency that extracts the maximum possible BTUs from the acetylene supply. For the industrial technician, this translates to a hotter flame cone and significantly reduced heating times compared to conventional tips.

One of the primary challenges in field brazing and soldering is environmental interference. The A-3 Twister Tip addresses this with a flame structure that is inherently stable. The high-velocity swirl creates a rigidity in the flame path, allowing it to resist blowout even in windy rooftop conditions or drafty construction sites. This stability ensures that heat is applied consistently to the workpiece, reducing the risk of cold joints or uneven brazing. The tip is sized as a #3, making it a versatile choice for a range of copper tubing diameters commonly found in residential and light commercial HVAC installations.

Integration is seamless with the Quick Connect system. The A-3 is engineered to fit Uniweld's quick-connect handles as well as compatible handles from other major manufacturers like TurboTorch. This keyless, tool-free connection mechanism allows operators to switch between tip sizes in seconds, optimizing their workflow when moving between different pipe sizes. Constructed from durable stainless steel and brass, the A-3 is built to withstand the thermal cycles and physical demands of daily industrial use.

By focusing on heat transfer dynamics, the helical blade ensures the flame wraps around the tubing, heating the entire circumference more evenly than a single-point flame. This wrap-around effect is critical for capillary action in silver brazing and soft soldering, ensuring the alloy flows deeply into the joint for a leak-free seal. The Uniweld A-3 is an essential component for any professional requiring high-performance air/acetylene tooling.
