While there are a lot of ways to cut metal, some methods are more effective than others. plasma cutter uses a particular range of versatility from metal fabrication jobs to decorative purposes. Because of its high utility, plasma is the ideal cutting choice for many projects. So, here’s why you should be using a plasma cutter.
What Is A plasma Cutter?
Plasma Cutting is a profile-cutting technique that can cut through any conductive metal. This includes metals like steel, aluminum, brass, titanium, and copper – both thick or thin. A plasma cutter sends an electric arc through a gas while passing through a constricted opening. Using extreme heat, plasma cutters elevate the temperature of the gas and convert it to a fourth state of matter called plasma. In conjunction with a compatible plasma torch, this instrument can pass through metals like steel, aluminum, brass, and copper with little or no resistance. This sharp welding process allows for cleaner, sliced lines, and sturdier constructions.
In general, plasma cutting is much lower cost than other metal-working processes such as laser cutting or water jet cutting. It is also a very immediate process, particularly when done by hand.
How Does a Plasma Cutter Work?
Plasma cutting works by passing a super fast jet of hot plasma through conductive metals to cut through it. To make the plasma, an electric arc is passed through a gas such as nitrogen or oxygen. This creates a fourth state of matter called plasma. The plasma can then be forced through a small opening like a nozzle, which can then cut through conductive metal. Generally, the plasma technique is safer than using a saw to cut metals which is why it is favored by many metal workers.
Plasma cutting is an effective way to cut thin and thick materials. Hand torches can usually cut up to 38 mm thick steel sheets, stronger computer-controlled torches can cut up to 150 mm thick steel sheets. Since plasma cutters produce a very hot and very localized “cone” for cutting, they are very useful for cutting and welding sheets in curved or angled shapes.
How Does a CNC Plasma Cutter Work?
A CNC plasma cutting system is a machine that carries a plasma torch and can move that torch in a path directed by a computer. The term CNC refers to Computer Numerical Control which means that a computer is used to direct the motion of the machine based on numerical codes in a program. A CNC plasma cutter is necessary to achieve accurate and edge-quality cuts for most metal fabrication projects.
A mechanized plasma torch is normally straight and carried by the profile cutting table compared to that of a hand-held torch. CNC plasma cutting involves cutting through electrically conductive materials by utilizing an accelerated jet of hot plasma that is directed right at the material being cut; steel, aluminum, brass, and copper.
CNC plasma cutters vary widely in size, price, and functionality. The machines are highly accurate and fast cutting through, and slicing metals at speeds of up to 500 inches per minute. Plasma cutters require a plasma gas and an assist gas to function, and they vary according to the material being cut.
Advantages of plasma cutting
- operation of one or more burners depending on the series
- cutting off all electrically conductive materials
- cutting of high-alloy steel and aluminum materials in medium and large thicknesses
- excellent performance in small and medium mild steel thicknesses
- cutting of high-strength structural steel with lower heat input
- high cutting speeds (up to 10 times higher than with oxyfuel)
- any processing of high-quality blanks for medium and thick sheet metals
- plasma cutting guarantees automation
- plasma cutting under water allows very low heat exposure and low noise level at the workplace
Does a Plasma Cutter Need Compressed Air?
Compressed air is the most commonly used gas for lower-current plasma cutters. So great if you are cutting thinner materials from gauge to 2.5cm thick. Compressed air is often called shop air and some plasma cutters have a built-in compressor.
Many fabricators choose plasma systems with “dual-gas” or “multi-gas” capability. This means that a variety of plasma and shield gases can be used for various applications. Multi-gas torches offer the most flexibility for shops that cut a variety of materials. Different gases are used, depending on material type and thickness, in order to achieve the best balance of cut quality, parts life, productivity, and overall cost of operation. Most plasma system manuals tend to overwhelm the operator with a confusing array of cut charts and gas choices.
