Recently there has been much discussion concerning the worth of plasma arc and laser procedures for welding and cutting, but oxy-fuel remains the most widely used approach worldwide.
The gear is robust, simple to use and also the expense of entry is relatively modest. The gas cylinders could be leased, are mobile and, because power isn’t required, it is possible to cut and weld nearly anywhere.
You will find several thousand kinds of speciality and regular cutting hints and welding nozzles accessible. Some are intended to cut off the foundation of the I-beam or eliminate the head of a rivet. Other hints extend up to 24″ in the torch.

You will find hints made to match awkward spots or cut at unusual angles, and long-lasting hints with special metal wear bands.
Picking the proper cutting tip to the task is essential to safety and performance. It is simple once you utilise the 4-Step Method, but you want to know these four items about your equipment and project:
1. Seat Type
This is dependent on brand. You must be aware of the maker or model of the torch or the part number of this cutting hints that you wish to replace since this establishes the seat kind.
If this significant step is prevented, harm to the equipment or harmful flammable gas leakage may result.
2. Metal Thickness
The depth of the steel being cut is very important since the middle hole of this cutting and cutting tip is sized to supply the appropriate quantity of oxygen in the appropriate pressure for a particular thickness. The pre-heat orifice can also be sized to deal with the right levels of combined gas to heat a specified depth of steel adequately.
Tips are designed particularly for the software where they should be utilised. There are distinct hints used for cutting, cutting, and heat. Some cutting suggestions are specially designed to utilise automatic cutting machines for high-pressure cutting which empowers faster, cleaner, more precise cuts.
4. Fuel Gas
There are various kinds of gases utilised in oxy-fuel cutting operations. Cutting hints, designed differently for every fuel gasoline, optimise the method by which the oxygen and gasoline are delivered.
The most popular most versatile gas, acetylene, is quite simple to use for many functions. Pre-heat time for cutting and cutting is relatively brief because the firing temperature is between 5,600 and 5,800 F., But this gas is the priciest gas available and isn’t the very efficient for heating large areas.
Commonly used as a generic title for various kinds of gases. These range from particular fluids, using their particular chemical formulae, to gases which are primarily propane combined with ethylene or other substances which normally burn hotter than propane. Reducing, gouging, and heat can be carried out with reasonable efficacy. Pre-heat times could be more, but utilising the appropriate tip design can remove this matter. This gas isn’t usually used for welding.
Propane is the most efficient for heat due to its high BTU output and also the big heavy heating suggestions which are readily available. These gases aren’t used for welding.
