Supply connections
CAUTION!
Turn off the power source and the wire feeder.
The MobileFeed 301 AVS can be used with either DC Electrode Positive (DCEP) or DC
Electrode Negative (DCEN) polarity without modifications.
1.
Connect the welding cable (1) from the power source to the weld cable lug connection
extending from the rear of the MobileFeed 301 AVS feeder.
a)
Positive terminal for gas shielded flux cored or solid wires.
b)
Negative terminal for most gasless self-shielded cored wires.
WARNING!
Make sure that the welding cables are correctly insulated before
applying power to the power source. Uninsulated cable and parts can
arc when contacting a grounded surface. The arc may damage eyes
or start a fire. Body contact with an uninsulated weld cable connector,
or uncovered conductor can cause shock and severe injury, possibly
fatally.
2.
Connect a second welding cable (2) between the opposite polarity output connection
on the power source and the work piece.
3.
Connect the wire feeder work lead/voltage pick-up cable clip (3) to the work piece.
4.
If gas shielded wire is used, connect the inlet gas hose to the gas inlet connections on
the rear of the feeder.
5.
Make sure that all hose and cable connections are tight.
6.
Turn on the power source and close the contactor if the power source is equipped with
an output contactor control switch. Open circuit voltage must be present to operate the
wire feeder.
