5.2 Connection of welding and return cables
The power source has two outputs for connecting welding and return cables (see illustration
Front and rear), a negative [-] terminal (6) and a positive [+] terminal (8).
For MIG/MMA 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 work piece and ensure that there is
good contact.
For TIG process (requires optional TIG accessories), connect the TIG torch power cable to
the negative [-] terminal (6), see front illustration. Connect gas inlet nut to a regulated
shielding gas supply. Connect the work return lead to the positive [+] terminal (8) see
illustration Front and rear.
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.
5.4 Inserting and replacing wire
The EMP 215ic and EM 215ic will handle bobbin sizes of 100 mm (4 in.) and 200 mm (8 in.).
See TECHNICAL DATA chapter for suitable wire dimensions for each wire type.
