instead, the eye protection system will be darkened periodically to indicate that the electrode is pressing
too hard against the workpiece. The electrode's contact to the workpiece must be stopped for a short time
and the welding process must be started again.
The welding process can be interrupted at any time by lifting the electrode away from the workpiece.
8.2 Basics and tips
♦
The quality of the welding results is significantly dependent on the quality of the electrode abrasion.
♦
Always ensure faultless electrical contact between the workpiece and the contact clamp, i.e. establish
contact between the workpiece and the connection cable terminal at a bare metallic point.
♦
Free-handed welding leads to poorer results due to uncontrollable independent movements
of the hands. The hand supports on the microscope are intended to prevent this.
♦
The pressure on the electrode tip should only be light.
♦
A gas flow rate of approx. 2-3 litres/minute is recommended. The gas flow should be regularly checked
at the flow regulator and adjusted if necessary.
♦
The angle with which the workpiece touches the electrode tip significantly influences the flow direction
of the welding point.
♦
For welding tasks on deeper lying points, the electrode can be clamped such that it protrudes somewhat
further out of the nozzle. The gas flow rate should be slightly increased here.
♦
In many cases it is helpful to work with welding wire as a welding supplement. The use of solder
is not permissible.
8.3 Abrading the electrodes
Switch off the machine prior to exchanging the electrode. This prevents uncontrolled triggering of the welding
process. The electrodes should be abraded with a diamond disk with a fine grain. The recommended angle
of abrasion is approx. 15°. Abrading the electrodes should take place in an axial direction. The lower
the roughness depth of the tip surface, the calmer the arc burns and the higher the service life of the electrode.

9. Care of the system components
9.1 Care of welding device and welding microscope
The welding device and welding microscope require minimal maintenance under normal working conditions.
However, it is essential that a few points are observed in order to guarantee the function and to keep
the welding device fully operational for years to come.
♦
Check the mains plug and cable as well as all welding and connection cables regularly for damage.
♦
Check that the moving parts of the hand piece move easily.
♦
If necessary, you can clean the electrode threaded assembly on the hand piece with a lint-free cloth
to ensure optimal contact with the electrode.
