Miller plasma cutters are one of the best solutions for metal cutting, piercing and gouging. They are relatively inexpensive and very high quality. Miller plasma cutters can cut through any conductor of electricity, not just metal. They make less of a mess than oxy fuel cutters and they are able to pierce, bevel, gouge, stack cut and shape cut any type and size of metal.
Miller plasma cutters have become so popular over the years because they are very user friendly, clean and can be used for so many metal work applications. I am sure you know how tedious it is to handle band saws or cutting shears. Not only that, but shears are expensive (considering they can only do one thing) and they may not make clean cuts.
Before you buy a Miller cutter you have to consider what type and thickness of metal you will be cutting most of the time. Depending on the type and thickness of metal you will choose the appropriate output power, nozzle size and type of air or gas needed for the cutter.
All plasma cutters are rated on three different cutting types.
Rated Cut - this cut makes an incision at 10 inches per minute
Quality Cut - this test cuts thicker metals at a rate slower than 10 inches per minute
Sever Cut - this test demonstrates the thickest metal that a certain model of plasma cutter is able to cut (sever cuts often need to be cleaned up afterwards)
When you are shopping for cutters you will read a lot about these three different types of cuts. It is a good idea to know what type of cutting you plan on doing and purchase a cutter model that is suitable.
After you buy a cutter, the setup is really easy. All you have to do is connect the Miller plasma cutter to an air compressor, plug them both in and turn them both on. When something is so easy to use it is tempting to neglect proper safety guidelines, but you will not use that as excuse will you? There are risks involved with using cutters, the most severe are loss of life and limb. Make sure that you wear proper safety gear and use your common sense whenever operating dangerous equipment.
