Generally speaking, for a cutting machine with analogue circuit control or with analogue

circuit & digital circuit control, the performance characteristics are decided by the

parameters of various components. Cutting performance of the machines differ as a result

of the inconsistent parameters of the components, so even for the cutting machines of the

same brand, their parameters often differ from each other. In addition, cutting

performance of the machine may change on some extent, since parameters of the

components may vary according to the environment such as temperature and humidity,

etc.

One of the characteristics of digital control is that it is not sensitive to the change of

parameters; the performance of cutting machine will not be affected by the change of the

parameters of certain parts. Therefore, the consistency and stability of digital control

cutter is better than that of traditional cutter.

Powerful cutting performance



This machine is economic and practical since it can cut metals by adopting compressed

air as the plasma gas source. The cutting speed has increased by 1.8 times when

compared with oxyacetylene cutting. It can cut thick steel plates such as stainless steel,

copper, cast iron and aluminum conveniently and quickly. It is easy to ignite arc by

adopting HF arc ignition mode, and post-flow function is available. With simple operation

and high cutting speed, smooth cutting surface can be obtained, and polishing is

unnecessary.

2.5 System characteristics

Duty cycle

Rated duty cycle refers to the percentage of the normal work time of the machine under

rated maximum current holding in the period when taking 10 minutes as a period. The rated

duty cycle of this machine is 60%. Using the cutting machine continuously overrunning the

rated load may lead to overheating of the machine, and frequently using the machine

overrunning the rated load may accelerate the aging of the machine or even burn the

machine.
