12-1401-04 - Smith Little Torch #4 Curved Tip | 2,300 BTU | 12-1401-04

Precision Flame Control for Delicate Fabrication

The Smith Little Torch #4 Curved Tip (12-1401-04) is a premier accessory for professionals who demand exacting standards in soldering, brazing, and welding operations. Manufactured by Smith Equipment (now under Miller Electric), this tip is engineered specifically for the legendary Little Torch system, a staple tool in jewelry manufacturing, dental laboratories, and electronics repair. The standout feature of this component is its laser-drilled synthetic sapphire insert. This jewel orifice is critical for maintaining a perfectly regulated gas flow, ensuring that the flame remains concentric and stable without the fluctuations often seen in inferior metal-drilled tips. This stability is paramount when working on delicate filigree or heat-sensitive gemstones.

With an orifice diameter of 0.020 inches (Drill Size 76), the #4 tip occupies a versatile middle ground in the Little Torch lineup. It generates approximately 2,300 BTU per hour, providing enough thermal energy to melt commercially weldable metals, glass, and ceramics, while still retaining the control needed for fine detail work. The tip operates optimally at a low pressure of 5 PSI for both oxygen and fuel, consuming just 1.57 cubic feet per hour (CFH) of fuel and 1.88 CFH of oxygen. This efficiency not only conserves gas supplies but also ensures a safer, more manageable flame for bench jewelers working in confined studio spaces.

Flexibility in fuel choice is another significant advantage of the #4 tip. Unlike the smallest tips in the series (#1 and #2), which are restricted to Acetylene and Hydrogen, the #4 tip is compatible with Acetylene, Hydrogen, Propane, Propylene, and Natural Gas. This allows artisans to utilize the fuel source that best fits their workshop setup or specific project requirements without needing to purchase different tips for different gases. Whether you are resizing a platinum ring, repairing a vintage silver piece, or engaging in intricate metal sculpture, the reliability and performance of the Smith 12-1401-04 ensure professional-grade results. The curved design further enhances usability, allowing for better sightlines and ergonomic positioning during extended periods of use.
