The wire feed shut down circuit is used to stop the
wire feed in the event of a fault. The most common
use of the circuit is with water cooled guns. A flow
sensor is connected to the circuit to protect the weld-
ing gun if the water flow is interrupted.
The Power Feed™ 10M Single Wire Feeder has two
leads, 570A and 570B, located inside the wire drive
that are electrically common. If flow switch is used,
separate these leads and connect to normally closed
flow switch terminals when water is flowing. Connect
the flow sensor to these two leads.

The Power Feed™ 10M Single Wire Feeder wire drive
may be configured for either low speed or high speed,
depending upon the application. The wire feeders are
factory assembled for low speed operation and
include a gear for high speed operation.

1. Turn off power at the welding power source.
2. Open the wire drive door.
3. Use a 3/16" Allen wrench to remove the screws
holding the feed plate to the wire feeder.
4. Use a Phillips screwdriver to remove the screw and
washers holding the gear to the shaft.
5. Remove the gear.
6. Lightly cover the shaft with engine oil or equivalent.
Install the desired gear onto the shaft.
7. Reassemble the screw and washers securing the
gear to the shaft.
8. Reassemble the screws in the appropriate position
for holding the feed plate to the wire feeder.

Best for most
GMAW and FCAW
welding. The low
speed gear ratio
provides the most
force for pushing
wires through long
guns or pulling
wire through con-
duits.
Suitable only for
small diameter
wires operating at
high wire feed
speeds. Feeding
force is less.
