Page 12: Working Principle
2.9 Working Principle The working principle of the TIG200AC/DC is shown in the flowchart below. The single phase 220V work frequency (50/60 Hz) AC is rectified into DC (approx 310V) which is then converted to a medium frequency AC (approx. 44KHz) by using an inverter device (IGBT module). -

Remarks Repeat welding function: In 4T mode, when you press the second time to stop the arc and if you press in a very short time, the output current will initially reduce to half, then the user can weld in small current as desired without ignition again. If you press the trigger again to stop the arc, but press in for more than 0.5 seconds, the arc will stop at your second press. -
