1. Use a reasonable cut distance
The cutting distance must be according to the requirements of the manual. The cutting distance is the distance between the cutting nozzle and the surface of the workpiece. When piercing, use twice the distance of the normal cutting distance or the maximum height that can be transmitted by the plasma arc.
2. When cutting, start from the edge
The small CNC plasma cutting machine cuts as far as possible from the edge, instead of perforating the cut. Small CNC plasma cutting machines use the edge as a starting point to extend the life of the consumables, so the correct method is to align the nozzle directly to the edge of the workpiece before starting the plasma arc.
3. Reduce unnecessary "arcing (or arcing)" time
The nozzle and electrode are consumed very quickly during arcing, so the torch should be placed within the walking distance of the cutting metal before starting.
4. Try to keep the torch and consumables clean
Any dirt on the torch and consumables can greatly affect the function of the plasma system. When replacing the consumables, put them on a clean flannel. Always check the connection ribs of the torch and clean the electrode contact surface with a hydrogen peroxide cleaner.
5. The nozzle can not be overloaded
Overloading the nozzle (ie, exceeding the operating current of the nozzle) can cause nozzle damage to be faster. The current intensity should be preferably 95% of the operating current of the nozzle. For example, the current intensity of a 100A nozzle should be set to 95A.
6. The thickness of the perforation should be within the allowable range of the machine system.
Small CNC plasma cutting machines shall not be perforated on steel plates exceeding the working thickness. The general perforation thickness is 1/2 of the normal cutting thickness.
