in this video i discussed the circuit diagram and how to repair and troubleshoot inverter IGBT based welding maching. this china MMA-200T Inverter IGBT Welder Machine - Circuit Explained & Troubleshooting Part -1, is single phase 220 VAC operated. it have a bridge rectifier which rectifies the main ac voltage into dc voltage, which are connected to pair of dc capacitors through a relay contacts and in parallel 110 ohms ntc resistor. this nts protects from inrush current and upon receiving relay drive signal it switches the rectified voltage to capacitors so, the ntc is bypassed to get full current to drive igbt.
after watching this video you will learn:-
how to #repair #inverter #igbt #welding machine or welder
2. functional description of inverter igbt welder machine
