100A TIG Welding Circuit IGBT UC3845 IRG4PC50U ETD59
SMPS (switch mode power supply) electronic welding machine circuit UC3845 control integrated based on the power transformer for the ETD59 used integrated 6 from exit smallest drive transformer coupled this transformer at the output of the IRG4PC50 the (600volt 27amp’s) IGBT’s. Instead of providing ETD59 supply out of the system with low-power SMPS circuit TOP224Y used. Operating current 3 mm by 100 authors mention that the electrodes have been used …
