6.4 LOADING SAVED TIG-WELDING PROGRAMS AND THE USER LEVEL "CUSTOM PROGRAMS"
All custom stored programs are
summarised
in
the
"Own
Programs" user level. This user
level displays the settings in
"Expert Mode". This means that
the
corresponding
underlying
energy characteristic curve is shown in addition to the
settings for time and power.
The other controls within "Own Programs" function as
"Expert Mode". The individual energy characteristic curves
can be selected here in addition to welding duration and
welding
power.
6.6 RESISTANCE WELDING MODE
The resistance welding mode
appears as a separate user level,
which can be accessed by
pressing the power regulator.
The welding process is released with the foot switch,
which is permanently activated in this welding mode.

7.1 TIG-WELDING INSTRUCTIONS
•
First connect a metallic blank section of the workpiece
with the contact clamp.
•
Lightly touch the area to be welded with the tip of the
electrode until welding begins. In doing so, it is
important to remain in the position where initial contact
is made until welding begins, i.e. neither to follow the
electrode with the workpiece if it retracts slightly in the
handpiece, nor to pull back.
APPLY EXTREMELY LIGHT PRESSURE OR NO PRESSURE TO THE TIP OF THE ELECTRODE!
The welding process proceeds automatically:
•
shielding gas flows around the welding point.
•
A signal tone announces the arc.
•
The arc triggers and the electrode retracts
slightly in the handpiece.
•
The shielding gas supply cuts off.
THE WELDING PROCESS CAN BE HALTED AT ANY TIME BY MEANS OF LIFTING THE ELECTRODE AWAY
FROM THE WORKPIECE.
