Plasma cutting using heat of high temperature plasma arc so that the metal portion of the workpiece incision or partial melting (and evaporation), and the momentum of the high velocity plasma by exclusion of molten metal to form a processing method incision. Features 1. Automatic and semi-automatic cutting dual mode selection 2. Digital precise control of cutting length plasma cutting machine with different working gas can cut a variety of metal cutting oxygen cutting difficult, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel) cut better; its main advantage is small when the thickness of the metal cutting, plasma cutting speed, especially in the cutting of ordinary carbon steel sheet, speeds of up to 5-6 times the oxygen-cutting method of cutting surface smooth, heat distortion, almost no heat affected zone. Practice: 1. When cutting before use and check that the power supply, gas supply, no water leakage, leakage, leakage, safe and reliable ground or zero. 2. The car, the workpiece should be placed on the proper position of the cutting machine classification, and should make the workpiece and the cutting circuit switched positive cutting machine, cutting down working surface shall be provided with slag pit. 3. It should be based on the workpiece material, type and thickness selected nozzle diameter, adjustment of the cutting power, within the gas flow and the electrode shrinkage. 4. Automatic cutting car should be running through empty, and the cutting speed is selected. 5. The operator must wear protective masks, welding gloves, hats, dust masks and filters soundproof earmuffs. Who do not wear goggles plasma arc prohibited direct observation, bare skin is prohibited near the plasma arc. 6.-cutting machine operator should stand upwind operation. Ventilation from the lower part of the table, and should reduce the operating table of open area. 7. Cutting, when no-load voltage is too high, you should check the electrical grounding, then zero and torch handle insulation should workbench and floor insulation, or electrical control system installation load disconnection breaker. 8. The high-frequency generator should be provided with a shield cover, with high-frequency arc, it should immediately cut off high-frequency circuits. 9. Using thorium, tungsten electrode should comply with Article 12.7.8 stipulates JGJ33-2001.
