1 INTRODUCTION
This manual describes use of the T4 control panel, which is installed in the AristoTig
400 power unit.
For general information on operation, see the power source operating instructions.
1.1 Control panel
1 Display
2 Knob for setting the current.
3 Increase (+) or Decrease (--) functions se-
lected by the function pushbuttons →
4 First, second and third function pushbut-
tons.
1.2 Remote control unit
Using a remote control unit, the primary parameters of the welding process can be
controlled from a device other than the control panel.
Aristo machines with intergral control panels should have program version 1.21 or
higher, in order for the remote control to function correctly.
Control panel’s behaviour on connection of the remote control unit
S The display freezes in the menu showing when the remote control is connected.
Measurement and setting values are updated, but only shown in those menus in
which the values can be displayed.
S If a fault code symbol is displayed, it cannot be removed until the remote control
has been disconnected.
2MENUS
The control panel uses several different menus. They are the main, measurement
and settings menus.
2.1 Main and measurement menus
The main menu is always displayed immediately after the
machine is started. The menu shows the values which have
been set. If the main menu is displayed when welding
begins, it switches over automatically to show the measured
values (measurement menu). The measured values will be
displayed even after the welding has been completed.

The settings menu can be accessed without losing the measurement values. It is only
when the knob is turned that the setting values are displayed instead of the
measurement values.
2.2 Settings menu
Different values can be entered in the settings menu.
To access the settings menu, press , or .
When the power source is switched off and restarted, the last values to be set are
recalled.

-- TIG
TIG
TIG welding melts the metal of the workpiece, using an arc struck from a tungsten
electrode, which does not itself melt. The weld pool and the electrode are protected
by shielding gas.
2--stroke
Gas pre--flow Slope
up
Functions when using 2--stroke control of the welding torch.

Slope down Gas post--flow
GB
In the 2--stroke control mode, pressing the trigger switch starts gas pre--flow (if
used) and strikes the arc (1). 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
Functions when using 4--stroke control of the welding torch.
Slope down Gas post--flow
In the 4--stroke control mode, pressing the trigger switch starts gas pre--flow (if
used) (1). At the end of the gas pre--flow time, the current rises to the pilot level (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). At the end of welding, the welder
presses the trigger switch again (3), which reduces the current to pilot level again
(with slope down, if in use). Releasing the switch again (4) extinguishes the arc and
starts gas post--flow.
HF
The HF function strikes the arc by means of a spark from the tungsten electrode to
workpiece as the electrode is brought closer to the workpiece.
Lift Arc
The lift a rc 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 Lift Arc function. 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 torch
from the workpiece: the arc strikes, and the current rises automatically to the set value.

Gas pre--flow
This controls the time during which shielding gas flows before the arc is struck.
Gas post--flow
This controls the time during which shielding gas flows after the arc is extinguished.
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 full current value is
reached.
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.
Current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
Irrespective of which menu is displayed, the setting value for the current can be
changed. The value is only displayed in the main menu.
