WELD WINDING, OUTPUT
RECTIFIER AND CHOKE
The AC voltage developed in the stator weld winding
is delivered through the current transformer to the out-
put rectifier bridge, where the AC voltage is rectified to
a DC voltage. The DC current path from the output of
the rectifier bridge is through the choke, where the DC
is filtered, to the negative and positive output termi-
nals.
The WELDANPOWER 125 provides 125 amps of con-
stant current DC welding for stick electrodes.
