Plasma cutting machine operation

A, plasma cutting machine and matters needing attention when cutting before use

1. Check and confirm the power supply, air supply, no leakage, leakage, water leakage, safe and reliable grounding or by zero.

2. Should be according to the type, the workpiece material and thickness of the selected nozzle aperture, adjust the cutting power source, gas flow and electrode in the drop-off.

3. Automatic cutting should run idle, and the selected cutting speed.

4. Operators must wear protective mask, welding gloves, hats, membrane filter dust mask and sound insulation earmuffs. Do not wear protective goggles it is forbidden to directly observe the plasma arc, bare skin close to plasma arc are strictly prohibited.

5. When cutting, the operator should stand in the windward operation. From the lower part of the workbench convulsions, and appropriate narrow on an open area.

6. Cutting, when no-load voltage is too high, should check electrical grounding, zero and cutting torch hand the insulation condition, should be workbench with ground insulation, or install light open circuit breaker in electric control system.

7. High frequency generator should be equipped with shielding cover, with high frequency arc, shall be immediately cut off the high frequency circuit.

Second, the plasma cutting machine cutting operation safety and personnel protective

1. The scene using plasma cutting machine machine, should have waterproof, moistureproof, prevent bask in the hangar, and shall furnish corresponding fire equipment.

2. When the cutting pressure container, sealed containers, oil drum, pipe, stained with combustible gas and solution artifacts, should first eliminate the pressure vessel and the pipeline, eliminate the combustible gas and solution, and then flush the poisonous and harmful,

Flammable substance; To have residual oil container, should first use steam, caustic wash mouth and open the cover, after confirm the container is clean, fresh water before being cut again! Within the container welding should be taken to prevent contact

Electricity, poisoning and asphyxia. Airtight container should be cut air flow, if necessary, in the outlet and inlet equipment ventilation equipment is installed in place; Container lighting shall not exceed 12 v voltage, welder and artifacts should be insulated; Outside the container

Should care by designated personnel. It is strictly prohibited in the spray paint and plastic container.

3. The pressure on the state of pressure vessels and pipelines, electric equipment, the stress of the bearing structure parts and containers of flammable, explosive forbidden for cutting.

4. Rainy days shall not be welded shears in the open. In wet area operations, the operator should stand in the items covered by insulation, and insulation shoes should a man wear.

5. After operation, cut off the power, shut off the air and water.
