Hayward, California (EastBayDaily) — Plasma cutting is the technique used for cutting metals of different thickness. A plasma torch is used for the cutting and makes use of a few inert gases. An electrical arc is maintained in this process, just as observed in the TIG welding process; these inert gases are blown on that arc which turns the gas into plasma. This plasma, though small in amount, is sufficient to melt the metal and cut it into two pieces. Basically plasma cutting techniques are used to get the fine finishing of the material to be cut. The hand cut material does not have that level of finishing. For industrial use, you need to have the finishing factor for every material. Plasma cutters use various methods for cutting. They give very high importance for environment in which the cutting is carried out. Plasma cutters in earlier times used very high voltage and high frequencies to start the arc. Plasma cutters also work near sensitive areas such as CNC (Computer Numerically Controlled) hardware or computers.
"Plasma cutters are of great industrial importance. They are actually the shapers of many industrial products that many of us hardly knows.", said Simon Katz, President Longevity welding. There are many leading brands in the market providing best plasma cutters. Most of them provide all the essential industrial features required for heavy job profiles. Best among the Plasma cutters can be judged from number of criteria. Some of the characteristics provided by the plasma cutters are Gouging, Piercing, Rated output, Rated cutting thickness for cutting mild steel, stainless steel, Aluminium, Recommended Generator Power and more. While choosing any plasma cutter, above such characteristics are to be taken into consideration. One of the best plasma cutter is the ForceCut LP-50D Pilot Arc provided by one of the leading brands in providing plasma cutters, Longevity. It has class of light industrial use and is specially designed for piercing. It has a rated output of 40 A at 60% or 30 A at 100% (110 V input) and has another variant. It can cut mild steel up to ¾ in, stainless steel ¾ in, and aluminium up to 3/8 in. Recommended generator power for this plasma cutter is 4000 watts. There are many such plasma cutters available with variable range and differing with respect to the use in the industry. Best plasma cutter can be judged by combining all of these qualities and choosing the best among them.
The analogue plasma cutters usually use a heavy mains-frequency transformer. The inverter plasma uses a different strategy. They rectify the main supply to DC and this is fed to a high frequency transistor. Initially MOSFET transistors were used, but now the use of IGBT is increasing. Plasma is associated with many processes. Gouging is one of them. In gouging, different torch configurations are used, and the metal is blown away from a larger distance. This technique also has gained great industrial importance. Plasma cutters are now days also used in CNC machinery. CNC stands for Computer Numerically Controlled. Using a CNC mechanism, provides more efficiency as all the cutting and calculations are done by the computer. The computer controls the cutting head and hence we obtain fine and sharp cuts.
