IGBTs Are helping CNC Plasma Cutting Machines

CNC machines with IGBTs are fast.

The CNC plasma cutting machine is one such device that has made the complex welding process simple and efficient. They are computer numerically controlled machinery which has been of great use to the metal working industry since a long time. Metals are used in every field of our lives making plasma cutter necessary equipment in the metal industry. If you deal with steel or metal, great plasma cutters are definitely music to your ears. CNC plasma cutters with IGBT transistors are fast and can start cutting instantly. These cutters are multipurpose, susceptible of penetrating and complicated cutting. These are able to cut any metal up to 6″ thick precisely. IGBT based plasma cutters are better than MOSFET based cutters in many aspects. With paralleled MOSFETs, if one of the transistors activates prematurely it can lead to a cascading failure of one quarter of the inverter. A later invention, IGBTs, is not as subject to this failure mode. IGBTs can be generally found in high current machines where it is not possible to parallel sufficient MOSFET transistors. IGBT plasma cutters are more costly but if you give emphasis on the cutting speed and quality then it’s the ultimate choice for you.

No preheating is necessary, so the torch can start cutting instantly. With speeds up to 500IPM, it can rival laser cutters based on the type of part. These cutters are versatile, capable of piercing, complicated cutting and beveling in one process. These can successfully cut any electrically conductive metal up to 6″ thick. Precision cutting is one of the attributes of CNC plasma cutters. These machines are paired with state of the art software and high accuracy components; the want for expensive secondary operations is eliminated. The torch head is computer controlled, making clean, sharp cuts. Tight integration between the cutting torch and software results in high superiority manufacture, high cut quality, fewer dross and high superiority edges. An IGBT based CNC engine may seem complex, the CNC (computer numerically controlled) software takes most of the guess work out of cutting. With a state of the art package, even a first time worker is capable of creating wonderful outcome. The machines are safe too, most systems offer an exhaust or down draft system to draw smoke away from the operator.

IGBT based plasma cutters create a warmth affected region and harden the edges of the material being cut. Many plasma cutting parts contains some dross that wants to be cleaned from the part but this has been minimized with today’s plasma cutting systems with elevated performance. CNC plasma cutters can cost more, but faster cutting speed and higher cut quality permit for earlier making with less labor intensive secondary operations. The long term efficiency and accuracy are elements which figure into the overall price of a plasma cutter, not simply the price.
