Precision Soldering with the Prest-O-Lite 1-A Tip

The ESAB Prest-O-Lite #1A Tip (639682) is a premium air-acetylene component designed for professionals who demand precision and reliability in their soldering and brazing operations. Engineered to fit the popular 300 and 400 series torch handles, this tip delivers a consistent, soft flame that is perfect for applications requiring controlled heat input. Whether you are working on fine copper tubing, jewelry repair, or intricate HVAC components, the 1-A tip ensures that you can apply heat exactly where it is needed without damaging surrounding materials.

As part of the legendary Prest-O-Lite line, now manufactured by ESAB, this tip benefits from decades of gas equipment expertise. The air-acetylene process utilizes atmospheric air for combustion, which simplifies your equipment setup by eliminating the need for a separate oxygen cylinder. This makes the system highly portable and cost-effective for field work. The 1-A size is specifically calibrated for smaller, more delicate tasks, providing a flame that wraps efficiently around small diameter pipes and fittings for a secure, leak-proof bond.

Durable Construction and Compatibility

Constructed from high-quality brass, the #1A tip is built to withstand the rigors of daily industrial use. It resists heat deformation and corrosion, ensuring a long service life even in demanding environments. The tip connects securely to Prest-O-Lite 300 and 400 series handles, offering a leak-free seal and optimal gas flow. Maintenance is straightforward, allowing operators to easily clean the orifice to maintain peak performance. For plumbers, HVAC technicians, and metal artisans, this tip represents the gold standard in air-fuel soldering technology.

Applications and Versatility

While primarily designed for soldering, the 1-A tip is also capable of light brazing and heating applications. Its soft flame characteristic minimizes the risk of overheating base metals, making it an excellent choice for working with heat-sensitive materials. From residential plumbing repairs to artistic metalwork, the Prest-O-Lite 1-A tip provides the versatility and control necessary to achieve professional results every time.
