LED Brightness/Intensity
By this option is possible to select the intensity of the
LEDs present in the user interface: three level can be
selected by the user. High level is reccomended when the
unit is used outside with high sun light luminosity
TIG Remote options
This remote section in Menu SYS is dedicate to select the
appropriate kind of remote devices connected. Unit
detects itself the present of a remote devices ( amptrol,
footpaddle): selecting AMP you indicate the unit and
amptrol is connected while selecting FOOT a footpaddle
is conected. By default this selection is for AMP. The
selection of FOOT and AMP changes dynamically also
the possibility to select and change parameters as
described in previous paragraphs.
UP/DOWN options
AMP MODE
Three operating modes, corresponding to different states
of the machine, are identified:
1) Before welding: pressing the UP or DOWN key
causes a change of value of the Set current
2) While welding: pressing the UP or DOWN key
causes a change of value of the Set current during
all phases of welding process except during the start
functions, where the UP/DOWN function is masked.
3) Pre/post Flow: pressing the UP or DOWN key
causes a change of value of the Set current.
The change will be realized in two ways depending on
pressed button time:
1) Step function: pressing the UP/DOWN button for a
minimum time of 200ms and releasing it, causes the
set current raises/falls of 1A.
2) Ramp function Pressing the UP/DOWN button for a
time greater than 1 sec., the set current start to
increase/decrease with a (5A/s) ramp. If press for
more than 5 sec increase/decrease with a ramp of
(10A/s). The current ramp will end when the
UP/DOWN button previously pressed is released.
3) When a remote (FOOT or AMP) device is present,
depending on welding process selected, the
UP/DOWN behavior is different.
In SMAW welding mode, the remote device set the
amperage setting in the whole range, bypassing the
main control knob in front User interface. In that case the
signals coming from UP/DOWN
are ignored
.
In GTAW mode of welding, the remote device set the
percentage of the main set delivered by the machine.
Regulating the main amperage, the UP/DOWN with
remote device will work as described above.
MEM MODE
By pressing torch buttons user will be allowed to change
over settings stored in memory locations from 1 to 9.
The feature is not available during welding.
MAX amparage option
This option allows the user to set the maximum current
supplied by machine
COOLER option
This option permits to the user to activate permanently the
water cooler when ON is selected.Cooler is switched OFF
only in Idle state.
For default AUTO is enable and the water cooler follows
the timeline of welding, green mode and idle state.
Cooler is switched OFF when green mode is activated;
the entering in IDLE mode confirms the OFF status of
Cooler.
Error Codes and troubleshooting.
If an error occurs, turn Off the machine, wait for a few
seconds, then turn ON again. If the error remains, a
maintenance is required. Please contact the nearest
technical service center or Lincoln Electric and report the
error code displayed on the meter of the Front Panel.
By ERR option (Menu SYS) is possible to see a list of the
last 10 different errors happened and recorder by the unit.
If the same error comes many times, only the last one is
recorder.
To reset the register, perform the follow procedure:
Push SEL button
for 5s. After that time the errors
list is reset
Release
SEL
Button.

Error code table
01
Input voltage too low
LED is blinking (at 5Hz).
Indicates that an Input Undervoltage
protection is active; the Machine restarts
automatically when the Input Voltage returns
in the correct range.
02
Input voltage too high
LED is blinking. (at 5Hz).
Indicates that an Input Voltage Overvoltage
protection is active; the Machine restarts
automatically when the Input Voltage returns
in the correct range.( 280Vac )
03
Wrong input connection
LED blinking. (at 5Hz).
Indicates that the power supply network to
which the machine is connected has serious
problems.
Turn OFF the machine and check the
power supply network.
04
Primary side voltage lock out
LED blinking. (at 5Hz).
Indicates that an Internal Auxiliary Voltage
fault condition is detected.
To restore the machine:
Turn OFF then ON the Mains Switch to
restart the machine.
06
Inverter voltage lock out
LED blinking. (at 5Hz).
Indicates that an Internal Auxiliary Voltage
fault condition is detected.
To restore the machine:
Turn OFF then ON the Mains Switch to
restart the machine.
