Plasma Cutter
 Product Description :
Features:
1.Full bridge inversion soft-switching technology to effectively reduce IGBT working loss;
2.Especial design for chassis with Platinum structure,has a strengthen make for radiator,fan so that the PCB will more stable and reliable;
3.Main PCB uses SMT technology, painting protection,decreasing failure rate effectively;
4.MCU+DSPmicrocomputer control technology to realize full digital control;
5.High-frequency transfer arc-sarting, 100% arc-sarting successfully;
6.Self-locking and nonself-locking for choosing,reduce intensity of work effectively;
7.Cutting power small volume, light weight, convenient movement, and high efficiency, low energy consumption and reduce the cost;
8.Wide working voltage range design, 60% of current output can also be ensured when three-phase input voltage is lowered to 250V;
9.Multiple protective functions, such as overheat, water shortage, overvoltage, undervoltage, high frequency, as well as reliable property;
