A brief insight into the plasma arc cutting machines

/ August 17th, 2011 / No Comments »

       Lots of people have been enjoying the advantages of utilizing a hand held air plasma arc cutting machine and they would rarely wish to return to any mechanical cutting processes ever. Fabricators, contractors, maintenance personnel, artists and even DIY personals are opting for plasma arc cutter. The benefits of using such cutting machines are many. They cut quicker, do not call for pre-heat cycle, cut any metal that conducted electricity, permitted portability around job web-sites and decrease the heat-affected zone. Moreover the productivity level is also improved and expense of cutting is lowered.

Essentially the operation method of a plasma arc cutting machine is comparatively very simple. But the toughest portion is selecting the plasma cutter that bets suites your wants and choosing the suitable accessories. The choice of the machine mainly depends on 3 elements. The thickness of the metal you intend to cut, the maximum thickness of the metal expected plus the speed of cutting needed. Similar to a welding machine, the size of the plasma cutter is determined by the amperage and voltage capacities. But quite contrarily towards the welding process, the plasma cutting needs reasonably high voltage and low amperage levels. It really is a prevalent misconception to judge the plasma cutting machine based only on the amperage. Despite the fact that it can be crucial, the total output energy really should be given more consideration. On the other hand, the size of each and every plasma cutter would vary according to the manufacturer.

For acquiring a superior understanding of the production rates, typically in parts per hour, you need to check the cutting speeds of the metal being cut. This makes certain that the cutting portion of the operation does not block the process. In automated application, the cutting speeds usually develop into essential when in handheld applications, the cut high quality and operator satisfaction is given additional priority. Commonly the manufacturers supply cutting speed charts by which the cutting plasma speed performance might be compared. There is certainly no universal regular but the qualifying capacity might be determined with three standards; namely rated cut, high quality cut and server cut.

Two elements are usually required for plasma cutting; air and electricity. So the type of input energy readily available ought to be noted even though selecting a plasma cutting machine. If there is certainly only 115V main service, you could go for 12 to 25 amp plasma cutters that operate using 115 or 230V energy. It can be always recommended to make use of the ordinary air as the cutting gas in most plasma arc cutters. For mobile applications, bottled nitrogen is often used in the location of bottled air considering that it is comparatively low-cost. Moreover, for cutting stainless steel, nitrogen is better as it produces slightly much less oxidation since it’s drier than compressed air.
In dirty environments with heavy dust and metal shavings, it
would be better to use machines with wind tunnel technologies and fan-on-demand which are particularly out there with certain models. Is such machines, the cooling air flows in such a way that it doesn’t drive off the electronic components thereby avoiding accumulation of grinding dust on any vital components. In fan-on-demand machines, the cooling fan runs only when needed, minimizing the quantity of waste entering the equipment.
