Generally, both conventional and semi-automatic cutting require manual ignition, which takes a long time. In fact, the long-term use of automatic ignition not only solves the cumbersome problem of manual ignition, but also many CNC cutting machines purchased by enterprises are often just contacted or less contacted, so there are still some problems in operation. Next is the introduction of how to use the automatic ignition function of the cutting machine.
The working principle of the automatic ignition function of the portable CNC cutting machine is the combustion process of the plasma arc. The arc ignition method of the machine power supply is generally non-contact arc ignition. The torch of the CNC-operated cutting machine is about 2-3mm away from the plate, which is a good distance. Plasma cutting machines generally cut directly after arcing, so there is not much involved in automatic ignition.
Then there is the CNC-operated cutting machine, whose principle is to use the cutting process to burn oxygen. Obviously, ignition is essential; the ignition of the cutting machine mainly depends on the work of the solenoid valve; in the automatic ignition of flame cutting, it is necessary to adjust the cutting flame in advance. nature and cutting oxygen flow, this is a critical step and should be operated by an experienced master. After adjustment, automatic ignition is possible, which can be done by turning off the flame.
When operating, remember to ensure the distance between the cutting nozzle and the plate, generally about 2 mm, start cutting, hear a "pop", and the automatic ignition is completed. At this time, adjust the height of the flame cutting nozzle to a suitable height. Set the warm-up time in advance. After the warm-up time is completed, the cutting machine can work normally, and the operator only needs to adjust the height and speed appropriately.
