AT605 - Miller Smith AT605 6-Flame Acetylene Heating Tip for AW1A Handles

Technical Overview of the Miller Smith AT605 Heating Tip

The Miller Smith AT605 is a specialized light-duty multi-flame heating tip engineered for precision thermal applications using oxy-acetylene gas mixtures. Designed to interface seamlessly with Smith AW1A and AW10A torch handles, this component is essential for professionals requiring controlled, medium-intensity heat output. The tip features a six-flame configuration utilizing a #64 drill size for the orifices, which collectively generate an average thermal output of 41,550 BTU per hour. This specific BTU rating is achieved through calibrated flow rates of 29 cubic feet per hour (cfh) for acetylene and 32 cfh for oxygen, ensuring a balanced and neutral flame chemistry suitable for sensitive metallurgical work.

Structurally, the AT605 measures 10 inches in length, providing adequate standoff distance to protect the torch handle and operator from radiant heat during prolonged operation. The assembly is designed for medium-pressure gas delivery systems. It is critical to note that due to the flow characteristics of multi-flame heating tips, the use of high-flow flashback arrestors is strongly recommended to maintain safety standards without starving the tip of necessary fuel volume. Users may need to adjust outlet pressures slightly to compensate for any flow restrictions introduced by these safety devices. The tip is manufactured to meet the rigorous standards of the Smith Equipment product line, ensuring consistent flame stability and long service life under standard industrial conditions.

This tip is categorized as a "SD" (Standard/Light Duty) component, making it distinct from heavy-duty rosebuds used in structural steel fabrication. Its primary technical application lies in scenarios requiring localized heat treatment where a single welding tip would be insufficient, but a heavy-duty heating tip would be excessive. The multi-flame head ensures that heat is distributed over a wider surface area than a welding tip, reducing the risk of burn-through on thinner materials while providing enough thermal energy for effective brazing and hard-facing operations.
