WELDING CONTROLS

1. OUTPUT CONTROL-
used to preset the output voltage or current as dis-
played on the digital meters for the five welding
modes. When in the ARC GOUGING or CV-WIRE
modes and when a remote control is connected to
the 6-Pin or 14-Pin Connector, the auto-sensing cir-
cuit automatically switches the OUTPUT CONTROL
from control at the welder to the remote control.
When in DOWNHILL PIPE and CC-STICK modes if
a remote control is connected to the 6-Pin or 14 Pin
Connectors, the output is controlled by the remote
and the output control on the machine is used to set
the maximum current range for the remote.
EXAMPLE: When the OUTPUT CONTROL on the
welder is set to 200 amps the current range on the
remote control will be MIN-200 amps, rather than the
full MIN-MAX amps. Any current range that is less than
the full range provides finer current resolution for more
fine tuning of the output.
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 cur-
rent range of the CURRENT CONTROL of the
Amptrol.
2. DIGITAL OUTPUT METERS-
meters allow the output voltage (CV-WIRE mode)
or current (CC-STICK, DOWNHILL PIPE, ARC
GOUGING and TIG modes) to be set prior to weld-
ing using the OUTPUT 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 sec-
onds after welding is stopped. This allows the oper-
ator 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%.
