25A PLASMA ARC CUTTING MACHINE PLASMA30i INTRODUCTION The PLASMA30i is an inverter current power source machine, designed for cutting electrically conductive materials (metals and alloys) using the plasma arc procedure. The melted metal will be blown off by the high speed gas flow at the same time to form into narrow cutting slot, thus the metal can be melted and cut very rapidly. NEW CUTMASTER™ 60i PLASMA CUTTER OFFERS HIGHEST POWER-TO-WEIGHT RATIO, HIGH-VISIBILITY DISPLAY. Obviously, labor is the major cost of operation for plasma cutting. Mount the plasma cutter on a secure bench or cart that will keep the welder secure and prevent it from tipping over or falling.
