OVERVIEW

Precision Micro-Joining Solution

The Miller Smith Little Torch™ Outfit #23-1003P is a comprehensive gas welding and brazing system designed for applications requiring extreme precision and control. Engineered for professional environments such as dental labs, jewelry manufacturing, and industrial micro-fabrication, this outfit centers around the legendary Little Torch handle. Weighing a mere 1.5 ounces, the aluminum alloy handle offers unparalleled maneuverability, allowing operators to perform intricate joins without the hand fatigue associated with standard torches. The torch body is designed to produce a stable, thread-thin flame that can reach temperatures up to 6000°F (3315°C), providing the thermal intensity needed to weld steel up to 1/8-inch thick while maintaining the delicacy required for microscopic soldering.

Industrial Regulation and Safety

Unlike hobbyist butane torches, the 23-1003P outfit is built for industrial reliability. It includes heavy-duty Miller Smith regulators: the 30-20-540 for oxygen and the 30-15-510 for fuel gas. The fuel regulator features a CGA 510 connection, making it compatible with standard industrial acetylene and propane cylinders (as well as many propylene and natural gas setups). This specific configuration ensures consistent flow rates and pressure delivery, which are critical for maintaining a neutral flame on the smallest tip sizes. Safety is paramount in oxy-fuel processes; therefore, this kit comes pre-equipped with reverse-flow check valves (H698) to prevent gas backflow, significantly reducing the risk of flashback incidents.

Versatile Tip Selection

The kit is supplied with five curved tips (Sizes #3 through #7), each fitted with a synthetic sapphire orifice. This manufacturing detail ensures the flame shape remains perfectly concentric and stable, even after hundreds of hours of use. The range of tips allows the operator to scale their heat output from microscopic soldering on electronic components to heating larger masses of metal for casting or brazing. Whether utilizing acetylene for high-temperature welding or propane for cleaner brazing operations, the Miller Smith Little Torch delivers consistent, professional results.

FAQ

You will need industrial-style cylinders. The oxygen regulator fits a CGA 540 valve, and the fuel regulator fits a CGA 510 valve. CGA 510 is standard for most industrial propane tanks and many acetylene tanks (often referred to as 'POL' or 'B' tanks depending on the valve installed).

No, the regulators included in this kit (23-1003P) are designed for refillable industrial cylinders. They will not fit the small 1lb disposable propane or MAPP gas bottles found at hardware stores without specialized adapters not included here.

Yes. The torch handle and hose are compatible with all fuel gases. The included fuel regulator has a CGA 510 connection, which is the standard connection for Propane and is also used on many Acetylene cylinders. However, you must ensure your Acetylene tank has a CGA 510 valve (some small acetylene tanks use CGA 520 or CGA 200).

With the included tips and using Acetylene, the Little Torch can weld steel up to 1/8 inch thick. It can also melt up to 3 ounces of silver for casting applications.

This kit includes reverse-flow check valves (Model H698), which prevent gas from flowing back into the lines. While these provide significant safety, they are not full flashback arrestors. Check valves are generally sufficient for the low pressures used with the Little Torch.

The outfit comes with five curved tips: sizes #3, #4, #5, #6, and #7. These cover a wide range of flame sizes for different applications.

The flame temperature depends on the fuel gas used. With Oxygen and Acetylene, the flame can reach approximately 6000°F. With Oxygen and Propane, it is slightly cooler but still sufficient for most brazing and soldering tasks.

The kit typically ships with Grade T hose, which is required for use with propane and other alternative fuels. Grade R hose is for acetylene only. Since this kit is rated for propane, the hose material is compatible with all fuel gases.
