BX1 series AC arc welding machine circuit

The BX1 series AC arc welding machine is a three-core single-phase magnetic shunt moving iron transformer structure. The circuit is shown in Figure 9-1. There are two types of
current adjustment: coarse adjustment and fine adjustment. For coarse adjustment, you can replace the connecting piece on the output terminal board (when terminals 1 and 2 are connected, it is L
connection method, when terminals 2 and 3 are connected, it is II connection method). Fine adjustment is to turn the handle in the middle of the welding machine to change the position of the moving iron core, that is, to change
the size of the magnetic leakage shunt, thereby obtaining uniform current regulation.
