The Operating Specification Of The Plasma Cutting Machine Before Use

1. It is necessary to check and confirm that the power source, air source, and water source have no leakage, air leakage, or water leakage, and that the grounding or connection is safe and reliable.

2. The trolley and workpiece should be placed in proper position, and the workpiece and the cutting circuit positive should be connected. The slag pit should be provided under the cutting surface.

3. The nozzle aperture should be selected according to the workpiece material, type and thickness, and the cutting power supply, gas flow, and the inner shrinkage of the electrode should be adjusted.

4. The automatic cutting trolley should be run by empty cars and the cutting speed should be selected.

5. Operators must wear protective masks, welding gloves, caps, dust masks, and acoustic ear caps. Persons who do not wear protective glasses are strictly prohibited from directly observing the plasma arc. Exposed skin is strictly prohibited from approaching the plasma arc.

6. When cutting, the operator should stand upwind operation. The air can be drawn from the lower part of the table and the open area on the operating table should be reduced.

7. When cutting, when the no-load voltage is too high, you should check the electrical grounding, zero connection and cutting torch handle insulation, the workbench should be insulated from the ground, or in the electrical control system installed no load circuit breaker.

8. The high-frequency generator shall be provided with a shielding shield. Immediately after high-frequency arc ignition, the high-frequency circuit shall be cut off.
