GENERAL DESCRIPTION
The Power Wave is an inverter type power source that
can support most welding procedures. It is modeled
after a P.C. (Personal Computer). There are no specif-
ic welding characteristics designed into the power
portion of the machine. All welding characteristics are
programmed into the software package.
INPUT VOLTAGE
The Power Wave can be connected for a variety of
three phase voltages. The initial input power is applied
to the Power Wave through a line switch located on
the front of the machine. The voltage is connected to
the Protection Board where it is current limited before
being passed on to the input rectifier and reconnect
switches. The reconnect panel allows the user to
switch to low or high voltage and connect the Auxiliary
Transformer to the appropriate input voltage. The
Auxiliary Transformer supplies power to the fan motors
and, through the Protection Board, to the printed cir-
cuit boards and wire feeder(s).
