3.3.1
Manual electric welding (electrode welding)
"Electrode welding" allows simple welding works with covered electrodes (electrode holders are not
included in delivery)
Please pay attention to the following:
Stud welding technology necessitates that the electrode holder is connected to the negative pole.
Polarity may, however, be reversed by changing the plug-in connection of the earth and welding
cables. Two adapter cables are necessary for doing so (special accessories).
The welding current is adjustable from 80A up to 300A in 20A steps.
The welding current has to be set depending on the electrode diameter and the welding task.
Approx. 40A for each mm diameter of the electrode may serve as a standard value for the current
adjustment.
CAUTION
During electrode welding, the connecting socket "welding cable" and the connecting
plug "earth cable" are always live.
The open-circuit voltage has always a direct voltage of approx. 85 V!
3.3.2
TIG welding
TIG welding allows simple welding works using a TIG welding torch (welding torch is not included in
delivery).
Please pay attention to the following:
Stud welding technology necessitates that the electrode holder is connected to the negative pole.
Polarity may, however, be reversed by changing the plug-in connection of the earth and welding
cables. Two adapter cables are necessary for doing so (special accessories).
Only direct voltage (DC operation) is available as welding current. It is not possible to change over to
alternating voltage.
The current may be adjusted between 80A and 200A in 20A steps.
