CNC plasma cutting machine in use should pay attention to 6 details

1. CNC plasma cutting machine using a reasonable cutting distance

According to the requirements of the manual, the use of reasonable cutting distance, cutting distance, that is, the distance between the perforation of the cutting nozzle and the surface of the workpiece, as far as possible for the normal cutting distance of two times or the use of plasma bow can be passed through the maximum height.

2.CNC plasma cutting machine cutting should start from the edge.

Small CNC plasma cutting machine as far as possible from the edge to start cutting, rather than through the hole for cutting. Small CNC plasma cutter to start from the edge will prolong the life of consumables, so the correct way is to align the nozzle to the edge of the workpiece before starting the plasma arc.

3.CNC plasma cutting system to reduce unnecessary "arc start (or guide arc)" time

The nozzle and electrode are consumed very quickly when starting the arc, so the torch should be placed in the path of travel of the cut metal before starting.

4. CNC plasma cutter try to keep the torch and wearing parts clean.

Any dirt on the torch and wearing parts can seriously impair the function of the plasma system. When replacing consumables, place them on a clean cloth, be sure to check the torch connector fins, and clean the electrode contact surfaces and nozzle with a hydrogen peroxide based cleaner.

5. CNC plasma cutter nozzles should not be overloaded

Overloading the nozzle (i.e., exceeding the nozzle's operating current) will damage the nozzle more quickly. The amperage should be best at 95% of the nozzle's operating current. For example: 100A nozzle current should be adjusted to 95A.

6, CNC plasma cutting machine perforation thickness should be within the scope of the machine system allowable

Small CNC plasma cutting machine perforation should not exceed the working thickness of the steel plate, the general perforation thickness of the normal cutting thickness of 1/2.
