WELDING CONTROLS
1. OUTPUT CONTROL-
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, when the wire feeder con-
trol cable is connected to the 14-Pin Connector, the
auto-sensing circuit automatically makes OUTPUT
CONTROL inactive and the wire feeder voltage
control active.
When in the TOUCH START TIG mode and when a
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.

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 dis-
play the actual output voltage (VOLTS) and cur-
rent (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 weld-
ing 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%.
