Inverter Dc Mma/tig Welding Machine (Mosfet)

Following are the features of Inverter DC MMA/TIG Welding Machine (MOSFET):
Scope of application: Precise Instruments / Meters / Decoration / Hardware, Small parts / Maintenance.
Applicable materials: Stainless steel / Mild Steel / High Tensile Steel / Cr-Mo Steel / Copper / Titanium Alloy.
Circuit principle: The large power component MOSFET(field-effect transistor) is adopted to convert 50/60Hz industrial frequency into high frequency (100KHZ above).Then, output large power DC source by declining the voltage, rectifying the current, and through pulse-width modulation (PWM) technology. The weight and volume of the main transformer is significantly declined and the efficiency is increased by 30% above.
