Connecting welding and return cables

The power source has two outputs for connecting welding and return cables (see front
illustration), a negative [-] terminal (6) and a positive [+] terminal (7).
For TIG process, connect the TIG torch power cable to the negative [-] terminal (6), see front
illustration. Connect gas inlet nut to a regulated shielding gas supply.
For MIG/Stick process, the output to which the welding cable is connected depends on the
type of electrode, please refer to electrode packaging for information relating to the correct
electrode polarity. Connect the return cable to the remaining welding terminal on the power
source. Secure the return cable's contact clamp to the workpiece and ensure that there is
good contact.
5.3

Polarity change

The power source is delivered with the polarity changeover cable connected to the positive
terminal. Some wires, e.g. self-shielded cored wires, are recommended to be welded with
negative polarity. Negative polarity means that the polarity changeover cable is connected to
the negative terminal and the return cable to the positive terminal. Check the recommended
polarity for the welding wire you want to use.
The polarity can be changed by moving the polarity changeover cable to suit the applicable
welding process.
