As much as a plasma cutter is an important tool, choosing the right device is equally important to ensure that users achieve their desired objectives. While review sites such as Cuts Like Butter shed light on many issues regarding plasma cutters, understanding the following three features can help buyers make a reliable purchasing decision.
The cutting speed of a plasma cutter will determine the quality of the cut, of which some machines can deliver the cut in three qualities: rated, quality, and severe cuts. A rated cut is usually the finest in quality. In this arrangement, a plasma cutter uses the maximum speed to cut steel of medium thickness. Based on the mild thickness, the cut is often flat and clean. In a quality cut, the plasma machine takes a little longer to cut thicker steel.
On the other hand, in a severe cut, a plasma cutter works very slowly to cut very thick metals. The cut is not very smooth and may require a cleanup after cutting. While the process begins with a lower cutting speed, the speed increases as the thickness of the metal decreases. Buyers should be aware of the thickness of the materials they want to cut and the required speed.
Plasma cutters can switch on in two different ways: either by a contact start or by a high-frequency start, which is necessary when initiating a pilot arc. Users working near other devices such as computers, TV sets, or telephones should not use a plasma cutter with a high-frequency start mode, as this may interfere with the controls of such devices. Alternatively, a plasma cutter with a contact start feature causes no interference. The feature also allows the user to place the torch in an accurate position.
In hand-held plasma cutters, normal air aids in the cutting procedure. However, some people may prefer bottled nitrogen in place of bottled air. It is advisable to read reviews to find important information on the plasma cutters available in the market. Essentially, some users find it difficult to carry the plasma cutter along with the bottled gas. Finding a machine with an inbuilt air pressure can save the situation. It saves money and reduces the weight of the cutter.
In addition, buyers should be aware of the conditions under which they work so they can select the right plasma cutter to suit the corresponding environment.
