DTB Series Medium Frequency Inverter DC Spot Welding Machine
The medium frequency inverter spot welding machine can rectify three-phase AC to DC and DC inverters into medium frequency 1000Hz square wave through the inverter circuit composed of IGBT. Then medium frequency 1000Hz square wave is connected into the primary of welding transformer, and the welding transformer make it with lower voltage and rectify it to be a dc supply electrode with little pulssation to the electrodes to weld the work piece.
