Connection of Welding and Work leads

The power source has two outputs for connecting welding and work leads (see front illustration), a negative
[-] terminal (6) and a positive [+] terminal (7). For optional TIG process, connect the TIG torch power cable to
the negative [-] terminal (6), see front illustration. Connect the shielded gas hose fitting to the inlet on the rear
panel from the Regulator/Flowmeter For 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 work lead to the remaining welding terminal on the power source. Secure the
work lead's contact clamp to the work piece and ensure that there is good contact.

Polarity Change

The power source is delivered with the polarity changeover cable connected to the positive terminal. Some
wires, e.g. shelf-shielded cored wires, are recommended to be welded with negative polarity. Negative polar-
ity means that the polarity changeover cable is connected to the negative terminal and the work lead to the
positive terminal. 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. Move the polarity changeover cable from positive to negative terminal.
