DEFINITION OF WELDING TERMS
NON-SYNERGIC WELDING MODES
• A Non-synergic welding mode requires all welding
process variables to be set by the operator.
SYNERGIC WELDING MODES
• A Synergic welding mode offers the simplicity of sin-
gle knob control. The machine will select the correct
voltage and amperage based on the wire feed speed
(WFS) set by the operator.
WFS
• Wire Feed Speed
CC
• Constant Current
CV
• Constant Voltage
GMAW
• Gas Metal Arc welding
GMAW-P
• Gas Metal Arc welding-(Pulse Arc)
GMAW-STT
• Gas Metal Arc welding-(Surface Tension Transfer)
SMAW
• Shielded Metal Arc welding
FCAW
• Flux Core Arc Welding
CAC
• Carbon Arc Cutting
CAG
• Carbon Arc Gouging
GENERAL DESCRIPTION
General Physical Description
The POWER FEED® 25M is a premium portable wire
feeder for use with the Power Wave products. The wire
feeder features a 2 roll MAXtrac™ drive coupled to a
powerful motor for driving wire through difficult situa-
tions. The easy-to-use, MSP4 interface provides ready
access to all welding modes in the Power Wave. A six
button memory panel is included with the POWER
FEED® 25M and allows quick recall of favorite weld
procedures. All the components are packaged in an
engineered aluminum case protected by replaceable
skids.
The heart of the POWER FEED® 25M is the
MAXtrac™ drive. The patented features on the wire
drive offer tool-less changing of the drive rolls and the
wire guides for quick spool changes. Plus, the drive
can be configured for extra torque when feeding large
diameter flux cored electrodes.
The POWER FEED® 25M continues Lincoln’s lead
role of environmental protection for electronics. P.C.
boards are potted in epoxy and electrical connections
are protected with dielectric grease. Noise suppres-
sion components protect the POWER FEED® 25M
from stray signals and keep the feeder from interfering
with other digital equipment.
General Functional Description
The POWER FEED® 25M is best suited for applica-
tions were quality welds are expected. Combined with
a Power Wave power source, the POWER FEED® 25M
is great for aluminum, nickel, alloy and other difficult to
weld materials. Easy to use controls make it a great
feeder for consistent results with mild steel applications
too.
DUTY CYCLE
The POWER FEED® 25M is rated for 500 amps, 60%
duty cycle and 400 amps, 100% duty cycle. The duty
cycle is based on a 10 minute cycle.
For example, when welding at 500 amps, the POWER
FEED® 25M may run 6 minutes and must idle for 4
minutes.
