2.2 Symbol and function explanations
Voltage Reducing Device (VRD)
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 technician to activate the function.
TIG welding
TIG welding melts the metal of the workpiece, using an arc struck from a
tungsten electrode, which does not melt itself. The weld pool and the electrode
are protected by shielding gas.
DC, Direct current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
Pulsed current
Pulsing is used for improved control of the weld pool and the solidification
process. The pulse frequency is set so slow that the weld pool has time to
solidify at least partially between each pulse. In order to set pulsing, four
parameters are required: pulse current, pulse time, background current and
background time.
Parameter settings
1. Slope up
2. Welding current
3. Pulse time
4. Background current
5. Background time
6. Slope down
7. 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.
2 TIG WELDING
0460 447 174 -8- © ESAB AB 2018
Pulse current
The higher of the two current values in the event of pulsed current.
Pulse time
The time the pulse current is on during a pulse period.
Background current
The lower of the two current values in the event of pulsed current.
Background time
Time for background current which, along with the time for pulse current, gives the pulse
period.
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 start
The HF start function strikes the arc by means of a spark from the electrode to
the workpiece as the electrode is brought closer to the workpiece.
2 TIG WELDING
0460 447 174 -9- © ESAB AB 2018
LiftArc™
The LiftArc™ function strikes the arc when the electrode is brought into contact
with the workpiece and then lifted away from it.
Striking the arc with the LiftArc™ function:
1. The electrode is touched on to the workpiece.
2. The trigger switch is pressed, and a low current starts to flow.
3. The welder lifts the electrode from the workpiece: the arc strikes, and the current
rises automatically to the set value.
2-stroke
In 2-stroke mode, press the TIG torch trigger switch (1) to start the shielding gas
flow and iniate the arc. The current slopes up to the set current value. Release
the trigger switch (2) to start to slope down the current and terminate the arc.
The shielding gas will continue to flow in order to protect the weld and the
tungsten electrode.
A = Gas pre flow
B = Slope up
C = Slope down
D = Gas post flow

4-stroke
In 4-stroke mode, press the TIG torch trigger switch (1) to start shielding gas flow
and initiate the arc at a pilot level. Release the trigger switch (2) to slope up the
current to the set current value. To stop the welding, press the trigger switch again
(3). The current will slope down to the pilot level again. Release the trigger switch (4)
to terminate the arc. The shielding gas will continue to flow in order to protect the
weld and the tungsten electrode.
A = Gas pre flow
B = Slope up
C = Slope down
D = Gas post flow
Material thickness
The current is set automatically due to material thickness (mm/inch).
To increase or decrease the current, push on until the symbols for material thickness,
slope down and gas post flow no longer are active and set the current.
Gas post-flow
This controls the time during which shielding gas flows after the arc is
extinguished.
Active panel
Settings are made from the control panel.
Changing trigger data
This function permits changing between different welding data memories by a
double press on the trigger of the welding gun. Only applies for TIG welding.
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 equipment before activation. When the remote control unit is activated the
panel is inactive.
2.3 Hidden TIG functions
There are hidden functions in the control panel.
