Two basic varieties of Gas Welding Torches exist. The first type uses fuel and air to be able to heat metals although the second makes use of fuel and pure oxygen to produce a flame which is so hot that it really is able to weld challenging metals. Quite a few scenarios exist in which either selection of torches might be utilized.

Similarities exist between the techniques in which both kinds of torches are operated. Even so limitations also exist in relation to their interchangeability. Propane torches employed by plumbers are a prime example of Air-Fuel torches.

One of the most obvious limiting factors will be the heat (approximately 3500 degrees F.). Air is really a mixture of 30% oxygen and 70% nitrogen and as a result, the huge majority of the fuel expending in the course of the burning process is utilized to heat the nitrogen and this does not serve to increase the energy of the flame.

Regardless of this limitation, this type of torch is affordable to buy and is often employed for a wide selection of purposes. Their low heat means that this kind of torch is unsuitable for a substantial majority of welding operations. Nonetheless they prove suitable for use in soldering and brazing or for property orientated projects.

These torches can be utilized to repair air conditioning units and copper plumbing fixtures discovered in homes and workplaces. They’re invaluable for projects which involve the bending and shaping of metal or lead work.

Oxygen and fuel torches are normally referred to on the basis of the type of fuel that they use, oxy-map, oxy-propane and oxy-acetylene being superior examples. When pure oxygen is thrown into the mix, the heat produced drastically increases. The heat produced ranges in temperature.

Propane ordinarily Produces Heat of 5000 degrees F. whilst map produces heat of 6200 degrees F. Acetylene produces heat of 6500 degrees F. but it is also the priciest. The drawback of these varieties of gas torch kits is that they’re expensive. Nevertheless, in the past few years lots of outstanding mini setups have turn out to be out there at inexpensive prices.

The selection of function able to be performed with the use of these torches increases with the cost. Metals of increasing thickness and bigger selections of materials might be welded with the additional high-priced models. Oxygen and fuel torches are advantageous as having a alter of tip; they are able to perform cutting operations. Simple air and fuel setups are unable to do this.
