No-load voltage and arc column voltage:
The plasma cutting power supply must have a high enough no-load voltage to easily induce arcing and stabilize the plasma arc. The no-load voltage is typically 120-600V, and the arc column voltage is typically half of the no-load voltage. Increasing the voltage of the arc column can significantly increase the power of the plasma arc, thereby increasing the cutting speed and cutting a larger thickness of the metal sheet. The arc column voltage is often not achieved by adjusting the gas flow rate and increasing the internal pressure of the electrode, but the arc column voltage cannot exceed 65% of the no-load voltage, otherwise the plasma arc will be unstable.
