Connection of welding and return cables
The power source has two outputs for connecting welding and return cables: a negative [-] terminal (7) and a positive [+]
terminal (8) (see Figure 1).
5.2.1
For MIG/MMA process
For MIG/MMA process, the output to which the welding cable is connected depends on the type of electrode. Refer to
electrode packaging for information relating to the correct electrode polarity. Connect the return cable to the remaining
welding terminal (9) on the power source.
Secure the return cable's contact clamp to the work piece and ensure that there is good electrical contact. Connect the
torch connector to the Torch connection (6).
NOTE!
MIG welding guidance chart:
The backside of the door on the bobbin side displays a MIG welding guidance chart for
initial selection of welding controls. This is intended as a guide for setting parameters on
this equipment.
5.2.2
For TIG process
For TIG process, connect the TIG torch power cable to the negative [-] terminal (7), see illustration. Connect the gas inlet
nut on the TIG torch to the gas outlet connector (4) located on the front of the power source. Connect the gas inlet quick
connect (12), on rear panel, to a regulated shielding gas supply. Connect the work return lead to the return-cable terminal
positive output [+](9). Connect the torch connector to the negative output [-] (7) (see Figure 1).

Check the recommended polarity for the welding wire you want to use. Refer to electrode packaging for information re-
lating to the correct electrode polarity. The polarity can be changed by moving the polarity changeover cable to suit the
applicable welding process.
