How to Design the Speed of Plasma Cutting Machine

There are many factors affecting the quality of plasma cutting machine, such as no-load voltage and arc column voltage, cutting current, electrode shrinkage, cutting nozzle height and other various plasma arc cutting process parameters, which will directly affect the stability of the cutting process, cutting quality and effect.

Generally speaking, no-load voltage and arc column voltage, cutting current, electrode shrinkage, cutting nozzle height and other factors directly affect the compression effect of plasma arc, that is, the temperature and energy density of plasma arc. And the high temperature and energy of plasma arc determine the cutting speed, so it can be said that many of the above factors are essentially related to the cutting speed.

Plasma cutting machine, as a numerical control cutting equipment, should improve cutting speed as much as possible on the premise of ensuring cutting quality. This not only improves the productivity, but also reduces the deformation of the cutting parts and the heat affected area of the slit area. If the cutting speed is not appropriate, the effect will be opposite: the viscous slag will increase and the cutting quality will reduce.

At present, plasma cutting is divided into many kinds according to the difference of cutting auxiliary gas, and the cutting speed specifications of different auxiliary cutting gas are also different.
