7 Using the PUK 6
Issue EN 2022/05 PUK 6 Operating manual
Proceed as follows:
1) Check the function of the eye protection filter. To do this, connect the
eye protection system to the welding device. Press the button for the
eye protection test in the settings menu of the welding device. This
darkens the field of vision. This can be checked by looking through the
oculars. If the button for the eye protection test is pressed again, the
LED illumination must be visible again when looking through the ocu-
lars.
2) Check the flow rate of the gas. The optimal flow rate is 2 - 3 litres/mi-
nute.
3) Select the welding parameters.
4) Free the workpiece from contamination with a suitable cleaner.
5) Connect a metallic blank section of the workpiece with the contact
clamp.
6) Move the workpiece towards the electrode in the handpiece holding
arm.
7) Apply light pressure to establish contact between the workpiece and
the electrode. The welding process now starts automatically.
8) Do not release the contact between the workpiece and the electrode
until the welding process is finished.
9) By touching the workpiece again, you can trigger the next welding pro-
cess.
The fine welding device is equipped with a function to prevent the electrode
becoming welded to the workpiece by incorrectly pressing or pressing too
hard. If a welding point has already been set and too much pressure has
been exerted with the workpiece on the electrode when it comes into con-
tact again, the welding process is not triggered; instead, a signal tone will
indicate that no welding can be performed without contact interruption. The
electrode's contact to the workpiece must be stopped and the welding pro-
cess must be started again. The welding process can be interrupted at any
time by lifting the electrode away from the workpiece.
TIP: Always work with a well ground electrode.
TIP: Never weld "freehand", i.e. use the hand rests on the micro-
scope. Even a slight trembling of the hands can impair the
welding results.
