Operation Mode And Fault Analysis Of CNC Plasma Cutting Machine
Jul 01, 2017

1) CNC plasma cutting machine Torch contact with the workpiece Press the button to cut. Can be cut from the edge of the workpiece, the plate thickness is not large, but also at any point in the workpiece to start cutting. The torch can be tilted slightly perpendicular to the workpiece or to the side,

But in the middle of the workpiece openings, the torch should be slightly tilted to the side, in order to blow out the molten metal, cut through the metal.

2) Press the button and press the main circuit to turn on, and the high frequency oscillator will work until the cutting arc is formed and the high frequency oscillator will stop working. It can then be cut by the movement of the torch. While the cutting indicator lights.

3) CNC plasma cutting machine cutting must be cut through the metal can even move evenly, otherwise it will damage the nozzle. Moving too fast or too slow will affect the cutting quality.

4) CNC plasma cutting machine cutting pressure adjustment: cutting pressure is too high, the flow is too large, will affect the cutting thickness. Cutting pressure too small will affect the service life of the nozzle.

5) lift the torch away from the workpiece, you must send the handle button, then the plasma arc extinguished, the cutting process to stop.

6) CNC plasma cutting machine cutting process, due to the torch leaving the workpiece more than 2 mm and arc, you need to re-arc. 7) due to the connection time is too long cause the main transformer temperature exceeds 110 ℃, the thermal control switch action, the device will automatically shut down, can not start. Should be restarted when the transformer is cooled.

8) often remove the filter in the valve in the water, that is, counterclockwise rotation of the bottom of the screw, remove the water and then tighten. If the compressed air in the water too much, should consider the filter between the valve and the gas source plus a filter valve, otherwise it will affect the cutting quality

9) When cutting the workpiece without cutting, press the torch button as little as possible to avoid damage to the parts.

10) After cutting all the workpieces, turn off the power switch and the gas source valve.
