For constant voltage welding, place the CC/CV mode
switch in the CV position. Connect the wire feeder to
the CV negative output terminal and connect the work
to the positive standard output terminal. For electrode
positive, reverse the output leads. The negative stan-
dard output terminal is not used for CV welding of
either polarity. Refer to diagrams section to determine
the correct connection to the remote control recepta-
cle.
When the WFM is in the “CV” mode, the maximum
auxiliary power will be reduced by 25%. To obtain
maximum auxiliary output, place the CC/CV switch in
the CC position.
If the current rating of the welder is exceeded, a ther-
mostat will reduce the output voltage to approximately
5 volts. The thermostat will reset automatically as the
machine cools. If the thermostat trips, lower the wire
feed speed and output voltage or reduce Duty Cycle.

The output voltage is set with the voltage control dial
mounted on the control panel. Set the “Current
Range Selector" to the “190-120” position for optimum
welding characteristics. Changing the "Current Range
Selector” affects arc characteristics. Setting the
“Current Range Selector” one position to the right of
the "190-120” position will give a softer arc. If this
switch is placed one position to the left from the "190-
120” set point, the machine will produce a crisp arc
characteristic. The setting of the “Fine Current
Adjustment" has no effect on the operation in “CV”
mode.
For Coarse Current Control on the SAE-300 see oper-
ator manual.
