1 Voltmeter
When not welding and the wire feeder is not
associated with the WCC compatible weld-
ing power source or WCC Control, the volt-
meter will alternate between three dashes
and open circuit voltage.
If the decimal points on the voltmeter are
blinking the wire feeder is trying to associ-
ate to a WCC Control or welding power
source. See Section 4-6 for details.
When the wire feeder is associated with a
WCC compatible welding power source or
WCC Control the voltmeter will alternate
between preset voltage and open circuit
voltage while idle. While welding the feeder
will display the actual weld voltage at the
wire feeder.
When connected to a non-WCC welding
power source the voltmeter will alternate
between three dashes and open circuit
voltage while idle. While welding the feeder
will display the actual weld voltage at the
wire feeder.
When the wire feeder is in CC mode the
voltmeter will alternate between CC and
open circuit voltage while idle. While weld-
ing the feeder will display the actual weld
voltage at the wire feeder.
Whether the wire feeder is associated or
not the voltage displayed while welding is
an average reading over a time span of 6 to
8 seconds. If the weld time is less than 8
seconds, the voltage displayed may not be
accurate.
2 Wire Speed / Amperage Meter
Displays wire speed in Inches per Minute.
To display wire speed in Meters per Minute
(see Section 4-13).
Amperage displayed at the feeder is
approximate. Refer to power source for ac-
tual amperage. To display Amperage (see
Section 4-13).
3 Wire Speed Control
Use control to adjust wire speed. Maximum
wire speed may be limited by arc voltage.
4 Voltage Control
Used to adjust output voltage of welding
power source when wire feeder is associ-
ated with a WCC compatible welding power
source or WCC Control. Voltage may be
adjusted while not welding.
Has no function when the wire feeder is not
associated with a WCC compatible welding
power source or WCC Control.
5 Power Control Switch
6 Soft Start Switch
The Soft Start feature provides a smooth
start during most weld conditions. When the
trigger is pulled, the wire speed is approxi-
mately 50% of the weld wire speed, as set
by the wire speed control knob. After an arc
is established, the wire speed increases to
the weld wire speed.
When using small diameters wire, or with
inverter power sources, it may be neces-
sary to turn switch off to obtain smooth
starts.
7 CC/CV Switch
Use switch to match feeder with the output
of the power source.
.
The feeder will not associate with a
WCC Control or power source if the
switch is set to CC.
8 Trigger Hold Switch
Trigger hold allows operator to weld without
holding gun trigger.
To use trigger hold function, place trigger
hold switch in the ON position.
The operator must hold the trigger for a
minimum of 2 seconds, but no longer than
6 seconds before releasing it. Welding will
continue when trigger is released.
To stop welding, press and release the trig-
ger.
9 Jog/Purge Switch
Pressing the Jog switch allows the operator
to jog wire without energizing the contactor
or gas valve.
Pressing the Purge switch allows the oper-
ator to purge gas lines before welding and
to preset gas flow rate at the flowmeter.
After adjusting the switches, close and
latch the door before welding.
