Operation; Overview - ESAB MobileFeed 301 AVS Manuel D'instructions

5 OPERATION

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, possibly fatal injury.
2. Connect a second welding cable (2) between the opposite polarity output connection on
the power source and the workpiece.
3. Connect the wire feeder work lead/voltage pick-up cable clip (3) to the workpiece.
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.
7. Turn the wire feeder power switch to "ON".
8. Check all gas connections for leaks.
WARNING!
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.
9. If gas-shielded wires are used, adjust the gas flow meter to the desired flow rate by
closing the torch trigger switch or operating the gas purge switch.
10. Turn off the power source and the wire feeder when they are not in use.
