Propane torches work the best for small soldering or heating jobs because of their portability. While propane-oxygen combinations can reach a maximum temperature of 3,623 degrees F, or 1,995 degrees C, a propane-butane torch only goes up to 2237 degrees F, 1225 degrees C.
A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas or LPG. Propane and other fuel torches are most commonly used in the manufacturing, construction and metal-working industries.
Liquid-fuelled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation. Fuel torches are available in a vast range of size and output power. The term blowtorch applies to the smaller and lower temperature range of these.
The Propane Hand Torch Cylinder is designed to fuel hand torches in order to complete jobs such as small soldering jobs, softening putty and paint, removing rusty bolts and nuts, and thawing frozen locks. Constructed of durable steel, the slim, lightweight cylinder is easy to grip and maneuver. Flame temperature in air is 3,600 degrees Fahrenheit.

A propane torch can reach temperatures of up to 3,623 degrees Fahrenheit when used in the open air. The flame generated by a propane torch is made of an inner and outer flame. The inner flame is dark blue, while the outer flame is a lighter shade of blue. Propane is a naturally occurring component of crude oil and natural gas.
There are a range of different makes and models on the market today. These days, even a small propane torch can still deliver excellent high temperature flames, so choosing the right model is more important than ever – you really can have a high degree of power right in the palm of your hand, so you need to trust the torch you’ve bought to ...
Propane torches have a small torch head that curves inward. This allows a concentrated flame to emit from the blowtorch. The closer the flame is to an object, the more precise the torch is and the higher the temperature of the torch. However, the farther away the propane torch is, the lower the temperature of the flame.
For their fuel/air torch they list: 1225°C = 2237°F with Propane-Butane Gas; For more theoretical/ideal values, consider this table (which also includes a few temperatures other than for gas/oxidixer mixtures):
Different fuel gasses (acetylene, propane, natural gas) burn at different temperatures and are best suited for different jewelry operations. This chart outlines the maximum temperatures at which common fuel gasses burn along with the melting points of some of the most common metals used in jewelry and metalsmithing.
