4-3. Front Panel Controls - Continued (See Section 4-2)
8 Arc Control LED
The LED lights to indicate the Arc Control
button is active. Light goes out when button is
inactive.
9
Arc Control Pushbutton
This button allows fine tuning inductance for
MIG programs, and Arc Control for RMD pro-
grams, and DIG for Stick programs. When the
button is pressed, the upper display (item 15)
shows INDU for inductance, ARC for Arc
Control, and DIG for Dig Control to indicate
which parameter is selected to change. The
range of possible values is 0-99 for
inductance and dig, and 0-50 for arc control
(factory default value is 25). Turn the Adjust
knob to change the parameter value. Press
button to deactivate arc control mode (LED
goes out).
10 Wire Feed/Gas/Contactor LEDs
The Contactor LED lights when the output
contactor is energized, making the weld
output terminals live.
11 Wire Speed And Amps LEDs
The lit LED indicates whether wire speed or
amps are being displayed.
12 Wire Feed Speed/Amps Display
Pushbutton
This button toggles display information in MIG
and RMD-Pro processes. Also, it is used to
enable and disable the contactor in panel
mode for stick, and TIG.
13 Lower Display
Press Wire Feed Speed/Amps Display button
to show weld amperage or wire feed speed in
lower display (the applicable LED under the
lower display lights to indicate which is
shown). When welding, actual value is shown.
If amperage was selected for display, the unit
will show actual welding amperage prior to
and while welding unless the the unit is in
Display Command Values mode. Only wire
speed command will be displayed while
welding if the unit is set in Display Command
Values mode, even if the Wire Feed
Speed/Amps Display button is pressed.
.
Displays show actual or command values
as determined by configuration menu
when using a PDA with PipePro Program
Management software (PipeProMgr).
Command values are displayed prior to
welding and actual values are displayed
while welding unless a PDA with PipePro
Program Management software (Pipe-
ProMgr) was used to set the unit in the
”Display Command Values” mode. In the
Display Command Values mode,
command values are displayed while
welding.
.
If a PDA with PipePro Program
Management software (PipeProMgr) is
used to change wire feed units (IPM, MPM)
or display welding information (command or
actual),save the changes and then turn the
power to the unit off and then on again for
the changes to be carried out by the unit.
14 Volts And Arc Adjust LEDs
The lit LED indicates whether voltage or arc
length is being displayed.
15 Upper Display
The upper display shows different information
depending on the active function of the unit
and the weld process being used. When the
display shows voltage (for a MIG process),
the Volts LED lights. When it shows arc adjust
[for an RMD-Pro weld process], the Arc Adjust
LED lights. However, during any weld process
(MIG and RMD), the unit will display actual arc
voltage unless a PDA with PipePro Program
Management software (PipeProMgr) has set
the unit in the ”Display Command Values”
mode.
16 Lock LED
The lock LED is illuminated when one or more
programs have been locked using an optional
PDA with PipePro Program Management
software (PipeProMgr). This may indicate that
some programs have been disabled. A dis-
abled program will not show up for selection.
Other programs may be locked against edit-
ing.
The lock LED will also illuminate if the selected
program is a custom program (indicated by a
C next to the program number), indicating that
it cannot be changed from the front panel. To
clear a custom program when lock is not en-
abled, the front panel can be reset (resetting
all 8 programs, see Section 4-15) or a new
program can be loaded from the PDA.
