ST605 - Smith ST605 Multi-Flame Acetylene Heating Assembly

Heavy-Duty Acetylene Heating Performance

The Miller Smith ST605 is a high-performance, heavy-duty heating tip designed for industrial oxy-acetylene applications requiring substantial heat input. Part of the renowned Smith Equipment ST Series, this multi-flame tip is engineered to deliver approximately 124,670 BTUs per hour, making it an essential tool for fabrication shops, shipyards, and heavy equipment repair facilities. The tip features a 12-flame configuration with a drill size of 57, ensuring a broad and intense heat pattern that efficiently transfers thermal energy to the workpiece.

Technical Specifications and Compatibility

Measuring 19 inches in length, the ST605 provides excellent reach and helps maintain operator safety by keeping hands away from the intense heat zone. It is specifically designed for use with Acetylene gas and is compatible with Smith Equipment heavy-duty torch handles, including the WH200, SW1A, and SW1B models (also compatible with legacy SW1 and WH200A handles). The tip assembly is robustly constructed to withstand the rigors of daily industrial use, ensuring consistent performance and longevity.

Safety and Manifolding Requirements

Due to the high volume of gas required to sustain the 124,670 BTU output, proper gas supply management is critical. Acetylene must not be withdrawn at a rate exceeding 1/7th of the cylinder's capacity to prevent the withdrawal of acetone from the cylinder. Consequently, the ST605 requires the manifolding of at least two standard acetylene cylinders to provide a safe and adequate fuel supply. Operators must ensure they are using high-flow flashback arrestors and appropriate regulator settings to compensate for flow restrictions and ensure safe operation.

Applications

This heating tip is engineered for a wide range of metalworking tasks, including:

• Heat Treating: Controlled heating for altering physical properties of metals.
• Bending and Straightening: Providing localized heat to facilitate the reshaping of structural steel, beams, and pipes.
• Pre-heating: Preparing thick plates and castings for welding to prevent cracking and ensure proper fusion.
• Shrinking and Forming: Precise heat application for fitting and shaping metal components.
