1. Cutting should start from the edge; cut from the edge as much as possible, not perforated cutting. Using the edge as the starting point will prolong the life of the consumable parts, the correct method is to direct the nozzle to the edge of the workpiece and then start the plasma arc.
2.Reduce the "arc (or arc guide)" time; the nozzle and electricity consumption is very fast when starting the arc, before starting, the cutting torch should be placed in the cutting metal walking distance.
3. Nozzle do not overload use; let the nozzle overload (i.e., exceed the working current of the nozzle), will damaged. The current intensity should be 95% of the working current of the nozzle. The current strength of the nozzle A 100 should be set to 95 A..
4.Adopt a reasonable cutting distance; according to the requirements of the instructions for use, adopt a reasonable cutting distance, the cutting distance is the distance between the cutting nozzle and the workpiece surface, when perforated, as far as possible to use the normal cutting distance of 2 times the distance or the use of plasma arc can transfer the standard height.
5. perforation thickness shall be within the allowable range of the machine system; the cutter shall not be perforated on a steel plate exceeding the working thickness, the usual perforation thickness being 1/2 of the normal cutting thickness.
6. try to keep cnc cutting torch and consumable parts clean: any dirt on cutting torch and consumable parts will greatly affect the function of plasma system. When changing the consumption parts, put it on a clean flannelette, check the connecting rib of the cutting torch frequently, and clean the contact surface and nozzle with hydrogen peroxide cleaner.
7. as little perforation cutting as possible, perforation is the back splash of molten steel will hurt the nozzle, which is one of the main reasons for the damage of the cutting nozzle, if the perforation is to be cut, in the hole with a drill bit pre-drilling, from the pre-drilling start cutting;
8. try to cut in the normal cutting thickness range rated by the portable cnc cutting machine, try not to cut on the cutting thickness, try to cut in this thickness range, can protect the cutting nozzle.https://www.wxsilvercoast.com/
