Daily use of CNC plasma cutting machine tips

1. Reduce unnecessary "arc start (or arc guide)" time; arc start nozzle and electrode consumption are very fast, before starting, the torch should be placed within walking distance of the cutting metal.

2. Cutting should start from the edge; as far as possible, start cutting from the edge, rather than cutting through the hole. Using the edge as the starting point will prolong the life of the consumable parts. The correct method is to aim the nozzle directly at the edge of the workpiece before starting the plasma arc.

3. Using a reasonable cutting distance; according to the requirements of the instruction manual, use a reasonable cutting distance, cutting distance that is the distance between the cutting nozzle and the surface of the workpiece, when perforated, try to use two times the distance of the normal cutting distance or use the maximum height that can be transmitted by the plasma arc.

4. Do not overload the nozzle use; let the nozzle overload (i.e., more than the nozzle's working current), will make the nozzle quickly damaged. Current strength should be 95% of the working current of the nozzle is appropriate. For example: the current strength of the nozzle of 100A should be set to 95A.

5. The perforation thickness should be within the allowable range of the machine system; cutting machine can not be perforated in excess of the working thickness of the steel plate, the usual perforation thickness of the normal cutting thickness of 1/2.

6. Try to keep the CNC cutting machine torch and consumable parts clean: any dirt on the torch and consumable parts will greatly affect the function of the plasma system. When replacing consumable parts to be placed on a clean flannel, to frequently check the torch connection ribbing, clean the electrode contact surface and nozzle with hydrogen peroxide-type cleaner.

7. The distance from the cutting nozzle to the steel plate as far as possible to maintain a constant, generally in 3-8mm or so, too far is not only too much power consumption, cutting penetration ability force will be reduced, and relatively more consumption of electrodes, so that the electrode life decreases; too close that is more simple, very expensive nozzle, nozzle life will be exponentially reduced, or even with up that is burned off.
