Plasma cutters are an effective metal cutting tool and with modern technology you can achieve cuts approaching laser accuracy which makes them a great cutting machine. Plasma cutters do not cut through metal using a flame as an oxy acetylene torch does. Instead plasma cutters use a high voltage charge to ionize a high velocity stream of inert gas which changes into plasma when it reaches very high temperatures. The plasma cuts through the metal by melting it with little impact on the surrounding metal and is very precise because of this.
It is only in recent years plasma cutters have achieved this level of precision. In earlier years the cutters were less precise and more of a blunt instrument. However recent technology has allowed the development of a smaller more focused flame to give a more accurate neater cut while using lower power. These machines can now be bought for less than US,000. These cutters have an inbuilt air compressor and are idea for a small workshop with enough flexibility to undertake a range of jobs.
Cutting Bits
The most expensive plasma cutters costing in excess of US .500 are more powerful and complex. An example of is Millers AutoArc 4500 with 27 amp power and a strong compressor. This powerful machine can through a half inch thick steel at a reasonable speed. In deciding which model to buy you should match the equipment with your needs. If for instance your usage is for occasional light tasks in a workshop then a lower cost entry level machine is appropriate. On the other hand if you perform work requiring regular use of the equipment then a more robust machine is worth buying. As with all equipment purchases you should spend no more than is necessary to get the job done.
