Ref. 804 855-A / 804 876-A
1 Voltmeter
Displays actual arc voltage while welding or
open circuit voltage while idle at the feeder.
The voltage displayed while welding is an av-
erage reading over a time span of 6 to 8 sec-
onds. If the weld time is less than 8 seconds,
the voltage displayed may not be accurate.
2 Wire Speed / Amperage Meter
Displays preset wire speed. While welding in
CC mode, actual wire speed is dependant on
arc voltage. To set wire speed display to:
Inches per Minute or Meters per Minute, see
Section 4-11.
Amperage displayed at the feeder is approxi-
mate. Refer to power source for actual amper-
age. To display Amperage, see Section 4-11.
3 Wire Speed Control
Use control to adjust wire speed within the
speed range selected by the wire speed range
switch, located on the inner control panel.
While welding in CC mode, actual wire speed
is dependant on arc voltage. Maximum wire
speed may be limited by arc voltage.
4 Jog/Purge Switch
6
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 pre-
set gas flow rate at the flowmeter.
5 Trigger Hold Switch (Optional)
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 mini-
mum of 2 seconds, but no longer than 6 sec-
onds before releasing it. Welding will continue
8
when trigger is released.
9
To stop welding, press and release the trigger.
6 Power Control Switch
7 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 estab-
lished, the wire speed increases to the weld
wire speed.
When using small diameters wire, or with in-
verter power sources, it may be necessary to
turn switch off to obtain smooth starts.
8 HI/LO Speed Range Switch
Use switch to select speed range. High range
is 100 to 800 Inches per Minute (2.5 to 20.3
Meters per Minute). Low range is 25 to 200
Inches per Minute (0.6 to 5.1 Meters per
Minute).
9 CC/CV Switch
Use switch to match feeder with the output of
the power source.
After adjusting the switches, close and latch
the door before welding.
