Voltmeter
If feeder displays dashed lines and OCV,
feeder is trying to associate with the
PipeWorx 350 FieldProt welding power
source. See Section 5-4 for details.
When the wire feeder is associated with the
PipeWorx 350 FieldProt welding power
source 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.
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 5-12).
Amperage displayed at the feeder is
approximate. Refer to power source for
actual amperage. To display Amperage
(see Section 5-12).

Wire Speed Control
Use control to adjust wire speed. Maximum
wire speed may be limited by arc voltage.

Voltage Control
Used to adjust output voltage of welding
power source when wire feeder is
associated with a WCC compatible welding
power source or WCC Control. Voltage
may be adjusted while not welding.
Voltage control has no function when the
wire feeder is not associated with a WCC
compatible welding power source or WCC
Control.

Soft Start Switch
The Soft Start feature provides a smooth
start during most weld conditions. When the
trigger is pulled, the wire speed is
approximately 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 diameter wire, or with
inverter power sources, it may be
necessary to turn switch off to obtain
smooth starts.

CC/CV Switch
Use switch to match feeder with the output
of the power source.

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
trigger.
9
Pressing the Jog switch allows the operator
to jog wire without energizing the contactor
or gas valve.
Pressing the Purge switch allows the
operator 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.
10 Polarity Indicators
Indicate whether feeder is connected to the
welding power source Electrode Positive
(DCEP) or Electrode Negative (DCEN).
