OVERVIEW

Precision Cutting with the Smith AC309 Airline Attachment

Transform your standard welding handle into a powerful cutting tool with the Smith AC309 Airline Standard Duty Cutting Attachment. Designed for professionals who demand reliability and speed, this attachment is a cornerstone of the Smith Airline series. Whether you are working in an HVAC environment, performing light fabrication, or creating metal art, the AC309 delivers clean, precise cuts on steel up to 3 inches thick. Its lightweight design reduces operator fatigue during extended use, making it an ideal choice for intricate work where control is paramount.

Effortless Tip Changes

One of the standout features of the AC309 is its compatibility with Smith's MC Series Graf-Tite cutting tips. Unlike traditional screw-in tips that require a wrench and often suffer from thread damage or seizing, Graf-Tite tips utilize a slip-in design. This allows you to change tips in seconds by hand, keeping your workflow uninterrupted. The soft seats on the tips ensure a gas-tight seal every time, reducing maintenance costs and downtime associated with worn threads.

Built to Last

Durability is woven into the DNA of the AC309. The attachment features solid silver-brazed joints and stainless steel tubes, providing exceptional structural integrity. The entire unit is nickel-plated, a finish that not only looks professional but serves a critical function: it reflects residual heat away from the torch and resists corrosion. This means your equipment stays cooler and lasts longer, even when exposed to the harsh conditions of a busy workshop. The double O-ring seal design further enhances longevity by providing a positive gas seal while allowing the head to rotate 360 degrees, giving you the flexibility to approach cuts from any angle without fighting hose resistance.

Versatile Fuel Compatibility

Flexibility is key in modern workshops, and the AC309 adapts to your needs. It is designed to function safely and effectively with all industrial fuel gases, including acetylene, propane, natural gas, propylene, and hydrogen. Simply pair it with the appropriate MC series tip for your chosen gas, and you are ready to cut. This versatility makes it a valuable addition to any tool kit, allowing you to switch between fuel sources without needing to purchase a completely new attachment.
