Be sure to properly insulate this connection before
applying power to the power source. uninsulated
cable and parts can arc when contacting a ground-
ed surface. the arc may damage eyes or start a fire.
Body contact with an uninsulated weld cable con-
nector, or uncovered conductor can shock, possibly
fatally.
B. Connect a second welding cable (work lead) between
the opposite polarity output connection on the power
source and the work piece.
C. Connect the wire feeder work lead (voltage pick-up)
alligator clip to the work piece.
D. If using with gas shielded wire, connect the inlet gas
hose to the gas inlet connections on the rear of the
feeder.
1. Make sure all hose and cable connections are
tight.
2. Turn power source “ON” and close the contactor if
power source is equipped with an output contac-
tor control switch. Open circuit voltage must be
present to operate the wire feeder.
3. Turn wire feeder power switch “ON”.
4. Inspect all gas connections for leaks.
unless starting to weld, do not allow the welding wire
to touch a grounded metal surface. the welding wire
becomes electrically hot when the secondary contactor
is closed. Keep fingers clear of the drive rolls; they will
start turning when the torch trigger is pressed.
5. If using gas shielded wires, adjust the gas flow-
meter to the desired flow rate by closing the gun
trigger switch.
6. Turn power source and wire feeder OFF when not
in use.
2.3 torch connectIons
The torch adaptor on the MobileFeed connects directly
to the wire feeder wire drive assembly, power and shield-
ing gas supply. Line up the torch connector with the wire
feeder adaptor, push on firmly and hand tighten the lock-
ing collar on the Euro Connector.
Make sure the torch chosen is of the proper rating for
the welding current to be used, has the proper size
and type of liner, the proper contact tip and the proper
guide tube.
2.4 supplY connectIons
Before making any connections between the wire
feeder and the welding power source, turn off power
to the welding power source and the wire feeder.
The MobileFeed 300 AVS can be used with either DCEP
or DCEN polarity without modifications.
A. Connect the welding cable from the power source;
positive terminal for gas shielded flux cored or sol-
id wires, or negative for most gasless self-shielded
cored wires, to the weld cable lug connection ex-
tending from the rear of the MobileFeed 300 AVS
feeder.
