Polarity change

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.
