2.2 Symbol and Function explanations
TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten elec
trode, which does not melt itself. The weld pool and the electrode are protected by
shielding gas.
Parameter settings
1. Slope up
2. Welding current
3. Slope down
4. Gas post flow time
Slope up
The slope up function means that, when the TIG arc strikes, the current rises slowly
to the set value. This provides `gentler' heating of the electrode, and gives the
welder a chance to position the electrode properly before the set welding current is
reached.
Welding current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
GB

bi15d1ea
Slope down
TIG welding uses “slope down”, by which the current falls 'slowly' over a controlled
time, to avoid craters and/or cracks. when a weld is finished.
Gas post-flow
This controls the time during which shielding gas flows after the arc is extinguished.
HF
The HF function strikes the arc by means of a spark from the electrode to the
workpiece as the electrode is brought closer to the workpiece.
LiftArct
With LiftArctthe arc strikes when the tungsten electrode is brought into contact with
the workpiece and then lifted away from it.
Striking the arc with the LiftArc functiont. Step 1: the electrode is touched on to the workpiece. Step
2: the trigger switch is pressed, and a low current starts to flow. Step 3: the welder lifts the electrode
from the workpiece: the arc strikes, and the current rises automatically to the set value.
2 stroke
Gas pre-flow Slope
up
Slope down Gas post-flow
Functions when using 2 stroke control of the welding torch.
In the 2 stroke control mode, pressing the TIG torch trigger switch (1) starts gas
pre-flow (if used) and strikes the arc. The current rises to the set value (as controlled
by the slope up function, if in operation). Releasing the trigger switch (2) reduces the
current (or starts slope down if in operation) and extinguishes the arc. Gas post-flow
follows if it is in operation.

4 stroke
Gas pre-flow Slope
up
Slope down Gas post-flow
Functions when using 4 stroke control of the welding torch.
In the 4 stroke control mode, pressing the trigger switch (1) starts gas pre-flow (if
used). At the end of the gas pre-flow time, the current rises to the pilot current (a few
ampere), and the arc is struck. Releasing the trigger switch (2) increases the current
to the set value (with slope up, if in use). When the trigger switch is pressed in (3)
the current returns to the set pilot current (with ”slope down” if in use). When the
trigger switch is released again (4) the arc is extinguished and any gas post flow
occurs.
Active panel
Settings are made from the control panel.
Remote control unit
Settings are made from the remote control unit.
The remote control unit must be connected to the remote control unit socket on the
machine before activation. When the remote control unit is activated the panel is
inactive.
VRD (Voltage Reducing Device)
The VRD function ensures that the open-circuit voltage does not exceed 35 V when
welding is not being carried out. This is indicated by a lit VRD LED.
The VRD function is blocked when the system senses that welding has started.
If the VRD function is activated and the open-circuit voltage exceeds the 35 V limit,
this is indicated by an error message (16) appearing in the display and welding
cannot be started whilst the error message is displayed.
Contact an authorised ESAB service technician to activate the function.

2.3 Hidden TIG functions
There are hidden functions in the control panel.
To access the functions, press for 5 seconds. The display shows a letter and
a value. Select function by pressing the right arrow. The knob is used to change the
value of the selected function.
To access hidden functions, press for 5 seconds.
Control panel TA23
Function Settings
A= gas pre-flow 0 - 5 s
I = min current 0 - 99%
Gas pre-flow
This controls the time during which shielding gas flows before the arc is struck.
Min current
Used to set the minimum current for the remote control T1 Foot CAN.
If the max current is 100 A and the min current is to be 50 A, set the hidden function
min current to 50%.
If the max current is 100 A and the min current is to be 90 A, set the min current to
90%.

3.2 Symbol and Function explanations
MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the
arc melts the electrode, and its coating forms protective slag.
Active panel
Settings are made from the control panel.
Remote control unit
Settings are made from the remote control unit.
The remote control unit must be connected to the remote control unit socket on the
machine before activation. When the remote control unit is activated the panel is

Control panel TA23
Function Settings
C= Arc Force 0 - 99
d= drop welding 0= OFF; 1= ON
F = regulator type 1= ArcPlustII; 0= ArcPlust
H = Hotstart 0 - 99
Arc force
The arc force is important in determining how the current changes in response to a
change in the arc length. A lower value gives a calmer arc with less spatter.
Drop welding
Drop welding can be used when welding with stainless electrodes. The function
involves alternately striking and extinguishing the arc in order to achieve better
control of the supply of heat. The electrode needs only to be raised slightly to
extinguish the arc.
Welding regulator
Welding regulator is a type of control that produces a more intense, more
concentrated and calmer arc. It recovers more quickly after a spot short-circuit,
which reduces the risk of the electrode becoming stuck.
SArcPlust(0) is recommended with basic type of electrode
SArcPlustll (1) is recommended with rutile and cellulosic type of electrode
Hot start
Hot start increases the weld current for an adjustable time at the start of welding,
thus reducing the risk of poor fusion at the beginning of the joint.
4 FAULT CODES
The fault code is used to indicate that a fault has occurred in the equipment. It is
indicated in the display by an E followed by a fault code number.
A unit number is displayed to indicate which unit has generated the fault.
Fault code numbers and unit numbers are shown alternately.
If several faults have been detected only the code for the last occurring fault is
displayed. Press any function button or turn the knob to remove the fault indication
from the display.
NOTE! If the remote control is activated, deactivate the remote control by pressing
to remove the fault indication.

4.2 Fault code descriptions
Below are described event codes at which the user himself can take corrective
action. If any other code is shown, send for a service technician.
Fault
code
Description
E 5 Intermediate DC voltage outside limits
The mains power supply is too high or too low. Too high a voltage can be due to severe
transients on the mains power supply or to a weak power supply (high inductance of the
mains power supply or a phase missing).
Action: Send for a service technician.
E 6 High temperature
The thermal overload cut-out has tripped.
The current welding process is stopped and cannot be restarted until the temperature has
fallen.
Action: Check that the cooling air inlets or outlets are not blocked or clogged with dirt.
Check the duty cycle being used, to make sure that the equipment is not being overloaded.
E 12 Communication error (warning)
Less serious interference on the CAN bus.
Action: Check that there are no faulty units connected on the CAN bus. Check the cables.
Send for a service technician if the fault persists.
E 14 Communication error (bus off)
Serious interference on the CAN bus.
Action: Check that there are no faulty units connected on the CAN bus. Check the cables.
Send for a service technician if the fault persists.
E 16 High open-circuit voltage
Open circuit voltage has been too high.
Action: Turn off the mains power supply to reset the unit. Send for a service technician if
the fault persists.
E 29 No cooling water flow
The flow monitor switch has tripped.
The current welding process is stopped and starting is prevented.
Action: Check the cooling water circuit and the pump.
E 41 Lost contact with the cooling unit
The welding data unit has lost contact with the cooling unit. The welding process stops.
Action: Check the wiring. Send for a service technician if the fault persists.
