Since its introduction in the 1950s, plasma cutting systems have become the preferred solution for metal cutting. And, it is excellently used in the following areas: shipbuilding and maintenance, trailer and auto repair, steel construction, agriculture and heating, ventilation and air conditioning, and general manufacturing. Although plasma cutting is very popular among customers, there are still many people who have misunderstood him. The following questions will be answered:
Myth #1: Plasma systems are expensive Although plasma systems are slightly more expensive than other cutting tools, it is important to realize that there is a close relationship between investment costs and long-term benefits. Fast cutting speed - without any warm-up of the workpiece - operators can quickly complete the job. Better cutting quality, less slag, and superior edge-cut quality means less labor-intensive finishing operations. Unlike flame cutting using combustible gases, most hand-held plasma cutting systems use compressed gas, which saves on cylinder rental and shipping costs.
Misconception 2: Only suitable for cutting thin materials Today, relying on advances in cutting torches, wearing parts, and power supply design, plasma system engineers can design systems with higher cutting power and thicker thicknesses - up to 80mm thick - And the system is smaller and the duty cycle is higher. As plasma technology continues to advance, the notion that plasma technology is only suitable for cutting thin materials is also out of date.
Misconception 3: Most suitable for cutting stainless steel Many plasma systems users purchase cutting systems for the first time, all for cutting stainless steel, aluminum or other non-ferrous metals. Some people still think that plasma systems can only be used to cut such materials. In fact, plasma systems are effective for cutting any conductive metal and are the most common method of cutting low carbon steel in the world.
Of course, the ability of the plasma system to cut stainless steel and aluminum is one of its main advantages compared to flame cutting, which is inefficient in cutting these materials. In addition, the plasma system is more effective in cutting sprayed, dirty, and even rusted steel materials, making it an essential tool for repairing heavy equipment, automobiles, and farm equipment.
Misconception 4: It is only used for cutting plasma systems for a wide range of uses. They not only can cut, but also perforate and bevel cut all types, shapes and sizes of conductive metal.
In fact, the plasma system is a highly efficient gouging tool. Some users first use plasma for gouging, followed by cutting. The plasma system has advantages that cannot be matched by other methods, such as less smoke and noise during gouging. Ordinary plasma gas gouging is used to remove weld roots for weld bevel machining and to clean up worn or cracked locations during repair or replacement.
Misunderstanding #5: Can't work in the field The plasma system needs power and air to operate. Some people think that the plasma system can only be used in places with fixed power and gas sources. Today's leading handheld plasma systems include the technology that enables them to achieve full performance — running with a properly sized motor-generator and a portable air compressor or compressed air tank. The latest frequency conversion plasma cutting system is small in size and light in weight, making it easier to transport back and forth in the field.
Misconception 6: Difficult to Operate It is not difficult to use today's leading plasma systems. Even the first operator who uses the plasma system can perform high-quality cutting within minutes of operating the plasma torch. When using an air plasma system, there is no need to adjust the gas and it is equipped with an inner fixed cover. The operator does not need to operate away from the machine. This allows the operator to drag the torch head directly along the workpiece and use pre-cut stencils to make cutting simple. The ergonomically designed torch handle and quick-connect torch technology make operation easier.
