While operating the CNC plasma machine, ensure that your follow appropriate specifications along with correct process for metal type, metal thickness, the quality of the cut, and productivity goals. Also, ensure that the plasma arc cutting is at an appropriate direction and correct process is selected for cutting the material.
  6. 6. What is a Plasma Cutter? Plasma CNC cutter is a process that cuts through the electrically conductive material with the help of hot plasma. Plasma cutting machines use a high-velocity jet of ionized gas that is delivered from the orifice. Plasma conducts electricity from the torch of the plasma cutter to the workpiece and heats the object, thereby melting the material. In simplest term, plasma machine can be used in various types of conductive metals such as mild steel, aluminum and stainless. It is ideal for non-ferrous materials that are less than 1 inch thicker. OMNI CNC plasma cutting machines are good at smooth cutting edges of the material giving clean and precise cut. Products are ideally suited for automotive fabrication, structural steel cutting, construction, sign shops, metal fabrication, decorative fencing.

This computer-controlled machine gives instructions through a computer over the manual handheld plasma cutter. It is compatible with optional CNC parts and improves the accuracy, flexibility, and productivity. When you purchase this most versatile CNC router machine for woodworking, plastic, stone, and, non-ferrous metals, you will receive plasma cutting software that needs to be installed before operating the machine. Also, a small brief out training is also given to help understand the operation of the plasma cutter.
  8. 8. Software Used to Operate the Plasma Cutter The software that comes with the plasma cutter is indubitably one of the most important parts of the machine. It allows the operator to successfully design, cut, and control the operation of the plasma torch. To create top quality designs with the plasma cutter, the operator must use AutoCAD for the CAD part and EXG Code for the CAM portion. The software that actually controls the plasma usually comes along with the CNC plasma table. CNC plasma cutting software STARCAM is very easy to operate. It consists of 3 modules, first drawing module (StarCAD), nesting module, (StarCUT), and numerical control emulation module (StarTEST). A short training is also given to the new user to make comprehend with the basics of a 4*8 plasma cutting machine. If you are interested in seeing the work process of this machine, you must read plasma machine software in action.
  9. 9. How CNC Plasma Cutting Evolved? Plasma cutting machines have come a long way. It has evolved to a great extent and considered as one of the most effective productive equipment for cutting metal sheets and plates. The plasma machine has greater flexibility and ability to cut diverse shaped materials on the basis of the instructions programmed. The machines were generally limited to cutting various patterns using X and Y axis of motion.
  10. 10. Maintenance Tips Neglecting the maintenance of the plasma CNC table would cause damage to the machine. The mechanical parts of the machine will wear causing abrasion. When the components of the machinery fail, troubleshooting or maintenance of the machine is a must thereby preventing any type of hazards. Here are some maintenance tips that you should consider preventing injuries and any sort of fatalities that may occur if the machine is not properly maintained.
  11. 11. Check the Torch Body Remove the parts of the torch and clean inner parts of the torch with cotton dabbed in the cleaner. Separate the torch from its mounting tube and slide it back. Also, ensure that the torch body has no leaks or damage to any of the connections. Clean the Torch Leads Wipe out the torch leads and remove the metal dust and dirt that is accumulated in the torch leads. The metal dust can cause dissipation of the high voltage needed to start the plasma arc. Also, check kinked or worn hoses, exposed wires, and damaged fittings that can be a reason for injuries and fatalities.
