• Lincoln Electric Chopper Technology®
- Delivers high quality welds by
increasing the control over the welding
arc.
• Multi-Process capable - Welds MIG,
flux-cored, stick, TIG, pulsed MIG, and
advanced processes like Pulse-OnPulse® and Power Mode®.
• Pulse-on-Pulse® - Improves cleaning
action when welding aluminum and
delivers a TIG-like appearance to the
weld bead.
• Power Mode® - Maintains a stable,
smooth arc for short arc welding on thin
material – great arc length control for
aluminum welding.
• Synergic control - Allows you to set
weld procedures with only one control for
simplicity.
• Rugged MAXTRAC® cast aluminum
industrial wire drive - Features dual
driven rolls, easy-turn numeric tension
indicator, brass-to-brass gun connections
and Lincoln’s 100% wire-supporting split
wire guide system.
• 3 Ways to Feed Aluminum - Choose a
Push Gun, Spool Gun or Push-Pull Gun
to feed aluminum. The POWER MIG®
350 has the electronics build-in for all
three methods - no PC board add-ons are
required.
Two Year Extended
Warranty Available in
the U.S.A. and Canada
KEY CONTROLS
Easy to use controls for high productivity and accurate settings.
A. Continuous WFS/Amps Control – In wire feed welding, adjusts
wire feed speed. In stick or TIG modes, adjusts amperage.
B. Continuous Volts/Trim Control – Adjusts voltage when MIG
welding. Adjusts the arc length (trim) when Pulse-MIG welding.
A
B
The Professional’s ChoiceSM – weld with traditional manual control or take
advantage of the included MSP3 digital panel for high tech weld features:
1. Weld Mode – Many synergic modes to select from for simple
one-knob control.
2. Preflow – Adjustable timer to initiate gas flow before the arc.
3. Post-Flow – Further protect your weld integrity by automatically
setting the gas to run a few seconds after the trigger is released.
1-9
1
4. Run-In – Adjustable speed at which wire strikes the plate to
enhance starting.
5. Start Procedure – Set start procedure, wire feed speed and volts
for an adjustable starting time.
6. Arc Control – Set arc control to crisp or soft depending on your
preference and application. In pulsed MIG, this control varies
the pulse frequency and background current. In Stick mode, it
adjusts the arc force.
7. Crater Control – Adjusts the ending weld procedure and ramp
down time.
8. Burnback – Adjustable time delay between turning off the arc
and the wire feed to prevent wire sticking to the puddle.
9. Spot Timer – Adjustable arc time for repetitive tack and spot
welds.
ARC PERFORMANCE
Lincoln Innovations for Challenging Applications
Waveform Control Technology® makes it possible to take advantage of Lincoln Electric innovations like these patented processes:
Pulse-On-Pulse® uses a
sequence of varying pulse
wave shapes to produce a
TIG-like bead appearance
and excellent weld properties
when MIG welding aluminum.
Pulse-On-Pulse® controls arc
length and heat input together,
making it easier to achieve
good penetration. See NX-2.10

Pulse-On-Pulse® on 3 mm Aluminum
Power Mode®
Power Mode® reduces spatter
and improves bead appearance,
even for low voltage
procedures on stainless.
Low Heat
(Background)
Power Mode® aids bead
wetting and penetration
on aluminum.
Power Mode® uses high-speed regulation of output power to
deliver extremely fast response to changes in the arc, for example,
when using a whip technique. The result is improved MIG welding
performance, including low spatter, very uniform, consistent bead
wetting and controlled penetration. Power Mode® benefits are
especially apparent on low voltage applications on thin steel and
stainless steel material less than 20 gauge (0.7 mm). See NX-2.60
High Heat
(Peak)
Pulsed MIG varies weld
current between peak (high
heat) and background (low
heat) current to provide
better control of heat
input, which minimizes
warping and burnthrough
on thin materials. Pulsed
MIG also enables flat,
horizontal, vertical up, or
overhead welding without
a slag system. Optimized
GMAW-P waveforms are
readily available to use on
aluminum, carbon steel,
high strength low alloy steel,
stainless steel, and nickel
alloys. See NX-2.70
Synergic MIG
2. Voltage is
automatically set.
1. Use one
knob to set
procedures.
Synergic MIG
Synergic control of voltage and wire feed speed
allows you to set weld procedures with only one
control for simplicity and ease of use.
