The characteristics and maintenance of plasma cutting machine

A plasma cutting machine is suitable for cutting, opening, digging, patching, and cutting various machinery, metal structures, and thin plates. With different working gases, it can cut all kinds of metals that are difficult to cut by oxygen, especially non-ferrous metals.

Product features of plasma cutting machine

The square tube welding structure is adopted, which has the characteristics of good rigidity, high precision, lightweight, and low inertia.

Vertical and horizontal drive: All use precision gear and rack drive. The guide rail adopts the domestic precision circular guide rail, which can perfectly guarantee the accuracy and balance of the movement.

The simple and easy-to-use operating system makes it easy to operate the plasma cutting machine.

Maintenance of plasma cutting machine

Confirm that the air switch is closed

There is no display on the display, and the fan does not rotate;

Confirm that the input cable wiring has power;

Confirm that the power supply has no phase loss.

Check whether the various patch cords in the machine are in poor contact

The display shows normal, and the fan rotates normally;

The control wire on the cutting gun is broken or the microswitch is damaged;

The button on the cutting gun does not work;

The control circuit is damaged (contact the supplier or manufacturer).

Whether the high voltage package is broken down

The IGBT is damaged; The abnormal indicator light is on, and the display shows normal;

Quickly restore the damage to the rectifier tube; The fan rotates normally;

Control board failure

The feedback circuit is faulty (abnormal indicator light is on).

There is a problem with the arc ignition part

The discharge nozzle is too far away or there is an adhesion phenomenon; The fan rotates normally,

The display shows normal;

The high-pressure package is damaged; Solenoid valve action, no dimensional arc output, abnormal indication;

The ignition relay is damaged; the indicator light does not light up;

Control circuit failure

The feedback circuit is faulty and the indicator light is damaged.

The quality of the air switch itself

The air switch cannot be closed;

The silicon bridge is damaged and needs to be replaced

Check whether there is a short circuit inside the machine.

The selection of plasma cutting machine should be selected according to the type and thickness of the processed material. The specifications of the plasma power supply range from 45A to 400A. Only when the power supply specification is selected and the thickness of the sheet is matched, can the ideal cutting effect be achieved. The dregs and the cut surface have a small degree of smoothness. Users should consult professional and technical personnel when selecting models so that the advantages of CNC equipment can be better utilized. If the plasma power supply adopts an imported inverter power supply, it can achieve accuracy close to that of a laser cutting machine.
