13717 - Smith Little Torch Multi-Orifice Heating Tip for Propane and Natural Gas

Precision Thermal Dynamics with the Smith 13717 Heating Tip

The Smith Equipment 13717 Heating Tip is a specialized multi-orifice nozzle engineered exclusively for the Smith Little Torch ecosystem. Designed to meet the rigorous demands of precision thermal applications, this tip provides a stable and controllable flame profile using alternative fuel gases. Unlike standard single-orifice welding tips, the 13717 utilizes a multi-port design to distribute heat energy more broadly, making it an essential component for applications requiring rapid thermal transfer without the localized intensity that might damage delicate substrates. It is specifically calibrated for use with Propane and Natural Gas, offering distinct performance curves for each fuel source to ensure optimal combustion efficiency and flame stability.

From a technical specification standpoint, the 13717 tip demonstrates impressive output capabilities relative to its compact form factor. When operating with Propane, the tip delivers a thermal output of approximately 3,497 BTU/hr. This performance is achieved at recommended pressure settings of 14 PSI for Oxygen and 10 PSI for the fuel gas, with flow rates of 1.4 CFH (Oxygen) and 5.0 CFH (Fuel). For facilities or setups utilizing Natural Gas, the tip adapts seamlessly, providing 2,300 BTU/hr at lower pressures of 7 PSI Oxygen and 5 PSI Fuel. The respective flow rates for Natural Gas operation are 2.3 CFH for Oxygen and 3.5 CFH for Fuel. These precise flow and pressure requirements are critical for maintaining the neutral flame chemistry necessary for high-quality brazing and heating operations.

The physical construction of the tip features a 6-inch length, which serves a dual purpose: it allows the operator to access recessed or difficult-to-reach areas within an assembly, and it provides a thermal standoff that protects the torch handle and the operator's hand from radiant heat. The tip is rated to melt up to 3 ounces of gold or silver, making it a powerful tool for metallurgical tasks that require significant heat input. Whether used for annealing, heat-treating small components, or pre-heating joints for soldering, the Smith 13717 ensures consistent performance. It is important to note that this tip is designed for heating and melting rather than fusion welding of ferrous metals, leveraging the specific combustion properties of alternative fuels to provide clean, soot-free heat.

Industrial maintenance and repair operators (MRO) will appreciate the reliability and repeatability of the Smith 13717. The orifice geometry is precision-drilled to ensure uniform gas mixing and velocity, preventing flashback and flame lift-off when used within the specified parameters. By adhering to the manufacturer's pressure guidelines, operators can maximize the lifespan of the tip and ensure safety during operation. This component represents the high standard of engineering associated with Miller Smith equipment, delivering professional-grade results for intricate thermal processing tasks.
