Polarity change
+/-- TERMINALS
The machine is delivered with the welding wire connected to the plus pole. Some
wires, e.g. gasless cored wires, are recommended to be welded with negative
polarity (welding wire connected to the minus pole and return cable connected to the
plus pole). Check the recommended polarity for the welding wire you want to use.
The polarity can be changed inside the wire feed cabinet:
1. Switch off the machine and disconnect the mains cable.
2. Bend the rubber covers back to give access to the cable lugs.
3. Remove the nuts and washers. Note the correct order of the washers.
4. Change the position of the cables to the desired polarity (see marking).
5. Install the washers in correct order and tighten the nuts to spanner tightness.
6. Make sure the rubber covers are covering the cable lugs.
