Micro torches use a small canister filled with a concentrated fuel source, typically argon. These torches have small nozzles and ignition devices that make them more like large propane torches than pocket lighters. While owners cannot easily carry around a micro torch, they are easy to store and can be used effectively with only one hand, making them ideal for a number of smaller applications. There are several types of micro torch tools.
Step One
Hobby - Hobby torches come in a variety of sizes, but tend to be some of the smallest torches designed for ease of use and handling. There are a number of crafts that benefit from micro torch use, including wood etching, carpentry and jewelry work. Micro torches can also be used for cooking purposes.
Step Two
Pen - Micro torch pens use long, thin attachments that produce a small yet intense flame in the shape of a pen or pencil. The torch helps users make detail designs when working with wood etching and other crafts. It can also be used to help make fires, correct minor metal flaws and bind electrical wires together.
Step Three
Automotive - Automotive micro torches are more industrial than hobby versions, designed for mechanical uses. Sometimes nuts and joints in an automobile can become locked together with dried oils or age. A micro torch provides enough heat to make the metal expand, usually enough for the mechanic to be able to adjust or remove the piece.
Step Four
Flexibility - Flexible micro torches have heads that are attached to a flexible base that can be bent and curved into different patterns. These micro torches have two key advantages. First, they allow users to angle the flame away from their hands, avoiding the possibility of serious burns. Second, they allow users to set the torch at the precise distance and angle they want for heat application, allowing for highly customizable work.
