Proper use of plasma cutting machines

Proper use of plasma cutting machines

Proper plasma pressure and flow plasma The correct air pressure and flow are important to the life of the consumable. If the air pressure is too high, the life of the electrode will be greatly reduced.

First, ensure the correct pressure and flow of the plasma

The correct air pressure and flow of the plasma is very important to the life of the consumable. If the air pressure is too high, the life of the electrode will be greatly reduced; if the air pressure is too low, the life of the nozzle will be affected.

Second, the use of reasonable cutting distance

According to the requirements of the instruction manual, a reasonable cutting distance is adopted. The cutting distance is the distance between the cutting nozzle and the surface of the workpiece. When piercing, try to use twice the distance of the normal cutting distance or the maximum height that can be transmitted by the plasma arc.

Third, the thickness of the perforation should be within the allowable range of the machine system

Plasma cutting machines cannot perforate steel plates that exceed the working thickness. The usual perforation thickness is 1/2 of the normal cutting thickness.

Fourth, the nozzle should not be overloaded

Overloading the nozzle (ie, exceeding the operating current of the nozzle) will cause the nozzle to be damaged quickly. The current intensity should be 95% of the operating current of the nozzle. For example, the current intensity of a 100A nozzle should be set to 95A.
