CUT-50D DC Inverter Non-Touch Pilot Arc Plasma Cutter Cutting Machine 110/220V. NON-TOUCH PLASMA CUTTER - Employ state of the art inverter technology. 50/60Hz Frequency is inverted to high frequency (over 100KHz) by V-MOSFET technology followed by step-down voltage and a rectification current. PWM TECHNOLOGY - Using Pulse-Width-Modulation (PWM) technology, the inverter power supply generates powerful DC welding currents.INCREASE EFFICIENCY - With the switch power inverter, the dimensions and weight of the main transformer are significantly reduced while increasing efficiency by 30%. LONG SERVICE LIFE - The non-touch arc is suitable for cutting plates with a thickness of more than 8mm (0.314 inch); Since the element does not directly contact the plate, the cooling process is faster and the element's service life is prolonged tremendously. HIGH QUALITY MATERIAL - Suitable for stainless steel, alloy steel, mild steel, copper aluminum, and other metal materials. Input Voltages: 110220V, 1PH, 50/60Hz. Input Current: 110220V, 1PH, 20A. Gas Supply: Clean, dry, oilfree air. Input Power Cable Length: 6 feet(1.8m).
