ENGLISH
1. Position the torch
with the electrode on
the workpiece.
2. Press the torch
trigger and keep it
pressed.
3. Lift the torch
slightly.
As soon as the
electrode is lifted
then the HF ignition
starts.
4. The arc ignites for
A few hundredths of
a second (time can
be set up).
5. The result of this
is a very precise,
not oxidized weld
-
ing spot without any
plastic deformation
of the sheet.
PROCEDURE WITH CONTINUOUS PRESSURE OF TORCH BUTTON
○ Bring the torch up to the work until the electrode tip is approximately 2 or 3 mm away.
○
Press (1T) the torch trigger.
○ The arc strikes without contact with the workpiece and the voltage discharges (HF) cease auto
-
matically.
○ The welding current reaches the pre-set value, by way of an up slope time, if programmed.
○ The welding procedure continues, at the pre-set current, for the time set with the spot time pa
-
rameter.
○ The current reaches the end current value in the time set in the down slope time parameter.
○
The arc is extinguished.
○ Gas delivery continues for the time set in the post gas parameter.
○ Touch the workpiece with the torch electrode.
