1.The spark plug does not fire when the ignition.
When ignition, there should be a clear discharge spark between the spark plug and the igniter body, which can be clearly seen, or there can be a clear spark discharge noise. CNC cutting machine which good? Texas Sean CNC Equipment Co. Ltd.
The spark plug does not fire, first check the main control board ignition indicator light in the operation of the "test fire" key, whether light 1-2 seconds to confirm that the main control board ignition control is correct.
Whether there is carbon on the spark plug will also cause the spark plug not to fire, it needs to be removed.
2.Check the high-voltage packets connected to the spark plug, as well as their interconnection and connection plug.
There was no gas coming out of the ignition.
In the operation of the "test fire" key, open fire can be used in the CNC cutting machine igniter fire, in order to confirm whether there is gas ejection when ignition.
If there is no gas ejection, the main control board and solenoid valve indicator light can be checked according to the gas path fault inspection and troubleshooting method. If the main control plate and solenoid valve indicator light indicates normal, and there is no valve clogging phenomenon, it is possible to ignite the gas nozzle hole clogging. The diagnosis is done by loosening the nut under the adjusting knob on the igniter and placing the knob in the water to see if there is gas ejection during ignition. Where there is gas and there is no gas at the igniter fire, it must be gas nozzle blockage. Gas nozzle hole is very small, for the Ф0.4mm. treatment method is to use a scrap hand with a hacksaw strip, grinding out a slender small tip, and then use it to cut the hole can be.https://www.wxsilvercoast.com/
