common cnc plasma cutting machine torch height controller problems and solutions

Many friends told me that when using CNC plasma cutting machine will occasionally appear torch height controller fault problem, but do not know what causes, do not know how to solve, the following small to analyze the main problems and solutions.

Failure phenomenon: when the CNC plasma cutting machine is lifted and adjusted, the machine suddenly stops and power cuts. Causes and Troubleshooting:

It is also found that when adjusting the flame gun by triggering the torch height controller, if the high-voltage input arc pin of the igniter is loose, the short circuit between the high-voltage arc line and the machine casing or the insufficient insulation strength will be caused, and the high-voltage ignition will damage the port of the driver system, thus causing this fault. This phenomenon must be avoided absolutely. Debugging and maintenance should be carefully checked. Check line insulation resistance, 1000V Mega meter must be greater than 300 Mega.

CNC plasma cutting machine torch height controller control template SG failure. Try replacing another control template.

Fault phenomenon: the regulator can only rise or down the cause of failure and exclude:

The torch height controller controls the poor contact of the template slot. Because in the industrial environment of high temperature dust, it is easy to cause static electricity to cause short circuit between electronic parts. Therefore, it is necessary to carry out soot cleaning regularly and keep the template clean.

The screw bolt of the lifting mechanism is worn out. Because of frequent action and lack of regular oil beating, the screw of the bolt is smoothed, so that the screw can not move the flame gun. Remove bolts and replace them.

The internal contacts of the elevator switch are damaged. The reason is that the regulator is used to adjust the distance between the flame gun and the steel plate for a long time. Replace it again.

CNC plasma cutting machine torch height controller switch wiring off or open circuit. Because the console has a certain rotation angle, there are hundreds of millions of wear and tear on the connecting thread. When processing, reserve a certain length of cable, so that it has a certain space for movement when the console rotates.
