The stator weld winding is connected to the reactor and range switch. The inductance in the reactor offers an impedance to current flow. The reactor coil is tapped at various points. As the range switch is rotated, dif- ferent amounts of reactor coil are brought into the cur- rent path. As more turns of reactor are brought into the circuit, the more impedance there is to current flow. Simply stated, the more reactor in the circuit, the lower the welding current.

OUTPUT BRIDGE, CHOKE, AND OUTPUT TERMINALS

The AC voltage developed in the stator weld winding is delivered, through the reactor and range switch, to the output bridge. The DC output current path is from the Output Bridge, where the AC voltage is rectified to a DC voltage, and then through the choke, where the DC output is filtered and on to the Output Terminals.
