GENERAL FUNCTIONAL
DESCRIPTION

• The POWER FEED® 25M Wire Feeder is a highly

versatile wire feeder with easy to use features that
make it easy for the operator to adjust the arc for
specific preferences.

• The new MSP4 panel clearly displays key welding

information. Use the MSP4 panel to quickly adjust
weld settings, arc starting parameters, arc end para-
meters and set-up variables.

• The POWER FEED® 25M Wire Feeder is provided

with an infrared red (IR) port. Transferring welding
settings is accomplished with a common palm com-
puter.

• When the POWER FEED® 25M Wire Feeder is cou-

pled to a Power Wave welding power source, the
result is a welding system with absolutely superior
arc performance.
