2.2
Symbol and Function explanations
TIG welding
TIG welding melts the metal of the work piece, using an arc struck from a tungsten electrode, which does not itself melt. The weld pool and the electrode are protected by
shielding gas.
Alternating current
The advantages of alternating current are reduced risk of magnetic arc blow and
good oxide break--up capacity when welding aluminium.
Direct current
A higher current produces a wider weld pool, with better penetration into the work
piece.
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
8. Balance
9. Frequency
10. Electrode preheating
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 positioned weld current is
received.

Time
TIG welding with pulsing.
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.
Balance
Setting the balance between positive (+) and negative (--) half waves during
alternating current (AC) welding. Provides optimal burn--in. Higher values produce
greater burn--in.
Frequency
An increased alternating current frequency produces a uniform and stable arc,
suitable during low current strengths and when welding extremely thin plates.

The HF function strikes the arc by means of a spark from the electrode to the work
piece as the electrode is brought closer to the work piece.

LiftArct
The LiftArct function strikes the arc when the electrode is brought into contact with
the work piece and then lifted away from it.
Striking the arc with the LiftArc functiont. Step 1: the electrode is touched on to the work piece. Step
2: the trigger switch is pressed, and a low current starts to flow. Step 3: the welder lifts the electrode
from the work piece: the arc strikes, and the current rises automatically to the set value.

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.

Gas post-flow
GB
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.
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
machine before activation. When the remote control unit is activated the panel is

Micro pulse
In order to select micro pulse, the machine must be in the pulsed current function
. The value for pulse time and background current is normally 0.01 – 2.50
seconds. By using the micro pulse, the time can go down to 0.001 seconds. When
the micro pulse function is active, times that are shorter than 0.25 seconds are
shown in the display without decimal points.

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 ArcPlust
Welding regulator ArcPlust is a new 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. Most welding
applications obtain the best results with ArcPlust ON (0).
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.
