Clarifying The Myths About Plasma Cutters

For more than fifty years the plasma cutters have been used to cut metal since they provide several advantages over other metal cutting methods

. But there are some myths related to the plasma cutters as many people have a misconception that plasma cutters are too expensive or too hard to learn. Conversely in realty, the plasma cutters are essential productivity enhancing tools.

It is true that plasma cutting systems are somewhat higher priced than some other cutting tools. But there is indeed a difference between price and cost. The plasma cutting systems are known for their high cutting speed and quality deliverance. Hence they provide productivity gain by saving operators time and money. This is because the cutting machines do not require preheating of the work piece thus enabling the operators to complete jobs quickly. The main advantages of using plasma cutters include better quality cut with less dross and better edge quality. The labor intensive finishing operations are required only in a minimum level in the plasma cutting method.

The advancement in plasma cutting technology has thankfully outdated the false notion that plasma is only meant for cutting thin materials. Advances in the design and function of plasma cutting torches, consumables and power supply design have enabled the operators to get more cutting power and thicker cutting capacity even when the system size have shrunk. However it is true that earlier the handheld plasma cutters did not meet operators expectations while cutting the thick metals. In addition, the plasma cutting machines provide some distinct advantages on thin materials like it causes less warping and only a smaller zone would be heat affected.

Many people purchase the plasma cutters for cutting stainless steel, aluminum or other non ferrous metals. There was a common disbelief that plasma cutting machines can only be used on such materials. But that is completely wrong since plasma can be effectively used to cut any electrically conductive metal and is one of the most popular means to cut mild steel. Plasma triumphs over oxyfuel cutting with its ability to cut stainless steel and aluminum. The cutters are even effective for cutting painted, dirty or rusted steel hence it can be used as a tool for heavy equipment repair, maintenance and other tasks.

Plasma systems are known for their versatile nature. They are capable of cutting, piercing and beveling metals of all types, shapes and sizes. With a change of the plasma cutting torch or consumables, some plasma cutters can be switched between hand and automated cutting. They are widely used on robotic arms as beveling and also gouging tools. The systems are user friendly and produce less smoke and noise. The gouging operations for worn or cracked parts are perfectly done by the cutters than any other equipment. Thus the versatility of the plasma cutters enables the operators to finish both welding and gouging and save time and money. Moreover the plasma cutters are portable and light weighted and can be carried to any desired location.
