WELDING MACHINE MMA MOSFET SERIES

Mosfet welding machine is short for Metal Oxide Semiconductor Field Effect Transistor, is a special type of transistor with a broad field effect and is widely used for large-scale circuits. Due to its sophisticated structure it has a high input impedance. MOSFET is a four-terminal semiconductor device that can control analog and digital signals.

Excess :
- Light weight and small size, easy to carry in all fields.
- The inverter engine has an efficiency rate of 80-90%
- The efficiency of the inverter welding machine can be operated using a generator
- The inverter machine's lifespan can be longer
- generate DC output, many choices of electrodes & fillers that can be used
- Superior performance
