Issue EN 2022/05 PUK 6 Operating manual
7.4 Switching off the PUK 6
Proceed as follows:
1) Set the contact clamp down such that no accidental contact can take
place.
2) Switch off the device at the main switch on the back of the device.
3) Close the valve on the gas cylinder.
The device is switched off.
7.5 Basic information and tips
• The quality of the welding result depends essentially on the quality of
the grinding of the electrode.
• Perfect electrical contact of the workpiece to the contact terminal must
always be ensured, i.e. the workpiece should be connected to the termi-
nal of the connecting cable or via a contacting tool at a metallically
bright point.
• Free-hand welding leads to poorer welding results due to uncontrollable
movements of the hands.
• The pressure on the electrode tip should only be light.
• A gas flow rate of approx. 2-3 liters/minute is recommended. The gas
flow should be checked regularly at the flow controller and readjusted if
necessary.
• The angle at which the workpiece touches the electrode tip significantly
influences the flow direction of the spot weld.
• For welding tasks at deeper spots, the electrode can be clamped in such
a way that it protrudes slightly longer from the nozzle. The gas flow rate
can be slightly increased in this case.
• In many cases, it is helpful to work with welding wire as a welding
filler. The use of solder is not permitted.
