WELDING CONTROLS (Figure B.1)
1. OUTPUT CONTROL: The OUTPUT dial is used to pre-
set the output voltage or current as displayed on the digi-
tal meters for the four welding modes. When in the CC-
STICK, 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 con-
trol.
When in the DOWNHILL PIPE mode and when a REMOTE
CONTROL is connected to the 6-Pin or 14-Pin Connector,
the OUTPUT CONTROL is used to set the maximum cur-
rent range of the OUTPUT CONTROL of the REMOTE.
Example:
When the OUTPUT CONTROL on the welder is set to 200
amps the current range on the REMOTE CONTROL will be
40-200 amps rather than the full 40-300 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 wire feeder has voltage con-
trol capability, when the control 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 OUT-
PUT control is used to set the maximum current range of
the CURRENT CONTROL of the Amptrol.
2. DIGITAL OUTPUT METERS
The digital meters allow the output voltage (CV-WIRE
mode) or current (CC-STICK, PIPE and TIG modes) to
be set prior to welding using the OUTPUT control dial.
During welding, the meter display the actual output volt-
age (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 decimal
point in each display will be flashing. The accuracy of the
meters is +/- 3%.
