5.4 Inductance settings (Fe/SS)
In certain cases especially for mild steel welding in different gases the quality of welding may
be improved by changing the inductance settings of the power source.
The inductance function is normally hidden, but can be invoked by the pressing and keeping
pressed the pushbutton (C) for 5 s or more. When this setting is available, all graphics from
the right side of the display disappears, and only number from 00 to 10 is displayed. This
number corresponds to the inductance value. 00 means that the inductance is low and the
welding arc is "sharp", 10 means that the inductance is high and the welding arc is "soft".
The value of the inductance can be set by means of the knob (B). Default setting is 05.
Recommendations:
• When the CO
2
is used it is recommended to set lower inductance then 05, for instance
from 03 down to 00
• When the Ar/CO
2
mixture is used, the operator should set higher inductance from 05
up to 10.
The display goes back to the regular appearance 10 s after the last movement of the knob
(B) or pressing pushbutton (C). The return to the regular mode can accelerate by again
pressing and keeping the pushbutton (C) pressed for 5 s.
5.5 Polarity change
+/- terminals
The power source is delivered with the welding wire connected to the plus pole. Some wires,
e.g. shelfshielded cored wires, are recommended to be welded with negative polarity.
Negative polarity means that the wire is connected to the minus pole and the return cable to
the plus pole. Check the recommended polarity for the welding wire you want to use.
The polarity can be changed as follows:
1. Switch off the power source and disconnect the mains cable.
2. Open the side panel.
3. Bend the rubber covers back to give access to the +/- terminals.
4. Remove the nuts and washers. Note the correct order of the washers.
5. Change the position of the cables to the desired polarity (see marking).
6. Install the washers in correct order and tighten the nuts to spanner tightness.
7. Make sure the rubber covers are covering the +/- terminals.
