What is a plasma cutter?

plasma cutter is a relatively easy -to -use tool for cutting steel and other electrically conductive metals. These cutters work using a high -cost electric arc and compressed gas, Usually air. An electric arc generated by an internal ionize electrode gas passing through the nozzle and creating a concentrated arc of plasma on Cutter's tip. The arc contact with the desktop makes a high temperature A circuit that melts the section less than 1/16 "(1.6 mm) wide. The strength of the plasma flow then literally blows the molten area to Workpiece, creating a relatively clean cut with small or no slag. Plasma The arch travels over a nozzle at a speed of up to 20,000 feet per second, And at temperatures up to 30,000 degrees Fahrenheit (16,600 Celsius)! amplifiers. To simplify their use, these machines often appear with on -board air compressors. Larger cutters are 220 volt system god output between 50 and 80 amperes. Hand models can be used for cutting conductive metal up to 5 inches (1,25 cm) While plasma industrial cutters can cut 2 inches (5 cm) metal.

One of the advantages of using a plasma cutter is that the surface The metal outside the cutting surface remains relatively cool; This prevents The deformation and damage to the color may occur in other cutting flames. AND The exact zone affected by a thin zone (HAZ) also allows the use of templates Cutting a curved line. Plasma decreases up to five times faster than traditional Tites and does not rely on highly deceptive gases. Many plasma cutters also Get off well like Gougers and can penetrate metal quickly and accurately.

Despite the advantages of plasma cutters there are some disadvantages. Electrode and nozzle of the cutter sometimes require frequent replacement that increases operating costs.Nevere materials such as wood or plastic cannot be cut with plasma cutters. Another minor disadvantage is that a plasma arch usually leaves a bevel of 4-6 degrees oncutting edge; Although this angle is almost invisible on thinner materials, it is evident in stronger pieces. Gas fuel torches are considered better than plasma cutters for thick steel.
