- 01 Check and confirm that the power supply, air source and water source have no leakage of electricity, air or water, and the grounding or zero connection is safe and reliable.
- 02 The trolley and the workpiece should be placed in an appropriate position, and the positive pole of the workpiece and the cutting circuit should be connected, and a slag pit should be set under the cutting working surface.
- 03 The nozzle aperture should be selected according to the material, type and thickness of the workpiece, and the cutting power, gas flow and electrode shrinkage should be adjusted.
- 04 The automatic cutting trolley should run empty, and the cutting speed should be selected.
- 05 Operators must wear protective masks, welding gloves, hats, filter dust masks and soundproof earmuffs. It is strictly forbidden to directly observe the plasma arc without wearing protective glasses, and it is strictly forbidden to approach the plasma arc with bare skin.
- 06 When cutting, the operator should stand in the upwind place to operate. The air can be drawn from the lower part of the workbench, and the open area on the workbench should be reduced.
- 07 When cutting, when the no-load voltage is too high, check the electrical grounding, zero connection and insulation of the torch handle, insulate the workbench from the ground, or install a no-load circuit breaker in the electrical control system.
- 08 The high-frequency generator should be equipped with a shielding shield, and the high-frequency circuit should be cut off immediately after starting the arc with high frequency.
- All welding machines use new electronic components.
- Industrial-grade four-module configuration, large current and strong cutting ability.
- Specifically designed for portable CNC and robot cutting.
- High load endurance, suitable for longtime cutting operations.
- Non-contact high-frequency arc ignition, high arc ignition success rate and low interference.
- With automatic protection functions: under-pressure, water shortage and overheating, to avoid damage to the gun head.
- Precise and infinitely adjustable cutting current suitable for different thicknesses workpieces.
- Grid adaptability, stable cutting current and plasma arc.
- Good characteristics, good arc stiffness, smooth incision, and excellent cutting process performance.
- The arc starting cutting current rises slowly, reducing arc starting impact and reducing cutting nozzle damage.
- Humanized and elegant appearance design, more convenient to operate.
- Three-proof design for key parts, suitable for various harsh environments, stable and reliable operation.
