12-1402-05 - Smith Little Torch #5 Twin Flame Heating Tip 12-1402-05

Technical Overview of the Smith Little Torch Twin Flame Tip #5

The Smith Equipment 12-1402-05 is a specialized Twin Flame Tip, size #5, engineered specifically for the Smith Little Torch system. This component is designed to maximize thermal transfer efficiency when working with tubular substrates, such as copper piping in HVAC and plumbing applications. By bifurcating the flame output, the tip generates two distinct heat sources that converge on the workpiece, allowing for simultaneous heating of opposite sides of a tube. This configuration is critical for ensuring capillary action draws brazing alloy evenly through the joint without overheating localized areas.

Technically, the tip features an orifice diameter of 0.029 inches (Drill Size 69) and is rated for a thermal output of 6,900 BTU/hr. Flow characteristics are optimized for 6 PSI on both the oxygen and fuel gas lines, yielding a fuel consumption rate of 4.70 CFH and an oxygen consumption rate of 5.64 CFH. This balanced flow ensures a stable, neutral flame capable of melting commercially weldable metals, glass, and ceramics. The tip is universally compatible with standard industrial fuel gases, including Acetylene, Hydrogen, MAPP®, Propane, Propylene, and Natural Gas, providing versatility for workshops with varying gas supplies.

The 12-1402-05 is rated for brazing copper pipe with diameters ranging from 5/16 inch to 3/4 inch. The dual-flame architecture significantly reduces the time required to reach liquidus temperature for silver solder and brazing alloys. Each tip undergoes 100% flame testing at the manufacturing facility to verify orifice concentricity and flame stability. This rigorous quality control ensures that the tip delivers the precision expected by professionals in jewelry manufacturing, electronics repair, and metal sculpture who rely on the Smith Little Torch for intricate thermal processing.
