WELDING CONTROLS (Figure B.1)
1. OUTPUT CONTROL-
The OUTPUT dial is
used to preset the output voltage or current as dis-
played on the digital meters for the four welding
modes. When in the CC-STICK, DOWNHILL PIPE
or CV-WIRE modes and when a remote control is
connected to the 6-Pin or 14-Pin Connector, the
auto-sensing circuit automatically switches the
OUTPUT CONTROL from control at the welder to
the remote control.
In the CV-WIRE mode, if the feeder being used has
a voltage control when the wire feeder control cable
is connected to the 14-Pin Connector, the auto-
sensing circuit automatically makes OUTPUT CON-
TROL inactive and the wire feeder voltage control
active. Otherwise, the OUTPUT CONTROL is used
to preset the voltage
When in the TOUCH START TIG mode and when
an Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.

DIGITAL OUTPUT METERS-
The digital
meters allow the output voltage (CV-WIRE mode)
or current (CC-STICK,DOWN HILL PIPE and TIG
modes) to be set prior to welding using the OUT-
PUT control dial. During welding, the meter display
the actual output voltage (VOLTS) and current
(AMPS). A memory feature holds the display of
both meters on for seven seconds after welding is
stopped. This allows the operator to read the actual
current and voltage just prior to when welding was
ceased.
While the display is being held the left-most deci-
mal point in each display will be flashing. The
accuracy of the meters is +/- 3%.
