Heavy fabrication welding operations will appreciate the broad multi-process
performance of the V450-PRO – featuring robust stick, MIG and cored wire
welding as well as precision Touch-Start TIG®performance. The V450-PRO
is targeted for shops commonly welding with .052" or larger diameter wires
that also require plenty of power for arc gouging repair work with a 3/8" carbon.
Take advantage of the benefits of inverter-based power sources, including a fast
response to changes at the arc and high input power efficiency and power factor
ratings for real savings on your electric bills. Combine those platform advantages
with the optional Advanced Process Panel to add pulsing capability and access
to Waveform Control Technology®and other arc performance Lincoln extweld®
innovations. Add a rugged MaxTrac®wire drive system feeder to build an
economical, high value, high performance welding package you can count
on for use in your factories around the world.
Processes
Stick, TIG, MIG, Pulsed(1), Flux-Cored, Gouging
Standard Welding Controls Optional Advanced Process Panel
Protective Door Reveals Added Controls:
• Features full remote and multi-process capability – stick,
Touch-Start TIG®, MIG, flux-cored and arc gouging.
• 5-570 amp output range for all recommended processes is low
enough for TIG welding on thin sheetmetal and robust enough for
arc gouging with a 3/8" carbon.

– Selectable Hot Start for stick welding: Turn it down for thin
material or turn it up to overcome cold starting at the beginning
of a weld.
– Variable Arc Control: Dial in the “soft” or “crisp” arc
characteristics you want for each application.
• Touch-Start TIG®makes it easy to achieve great arc starts with
minimal or no tungsten contamination.
• Clever stackable case design allows you to stack up to three units to
save valuable shop floor space.
• Supports 24, 42 or 115 VAC wire feeders.
• Heavy-duty construction, robust engineering and rigorous testing
result in tough IP23S rating for use in industrial environments.
• Front panel 15 amp 115 volt AC auxiliary power receptacles with
circuit breaker protection will power your lights, grinders or
gun/torch water coolers (on K2420-1 only).
• Easy-access front panel controls and connections are protected by
sturdy metal doors.
• Three year warranty on parts and labor.
• Manufactured under a quality system certified to ISO 9001 require-
ments and ISO 14001 environmental standards.

• .035"-3/32" cored wire
Delivers outstanding performance with a wide variety of shielding gas
mixes, including 100% CO2, Ar/CO2or Ar/O shielding gas for carbon
steel as well as helium blends for stainless welding.
5. CV-Innershield®
Features a wide voltage range and tight voltage control optimized for
Lincoln Innershield self-shielded flux-cored applications.
Arc Gouging accessible from all S ick and CV Welding Modes –
With a maximum 70 amps, the V4 0-PRO has plenty of power to
handle a 3/8" (9. mm) carbon.

Get the Results You Prefer
Hot Start
Regulates the starting current at arc initiation for stick or
TIG applications.
Set it to your preference to help overcome cold starts at the
beginning of a weld, restarting AWS E7018 or stainless stick
electrodes or to improve starting for tie-in welding on tack welds.
Turn it down for thin material or root welding on pipe. Turn it up
for thick material or general construction welding.
Variable Arc Control
Adds or reduces inductance (arc energy), particularly for short-cir-
cuit transfer mode. Arc Control increases or decreases the size and
frequency of arc droplet transfer.
Set it to your preference to help control spatter levels or electrode
stubbing as well as to improve weld toe wetting or to obtain a
uniform bead shape.
Turn it down to obtain a softer arc or turn it up for a stiffer, more
digging arc. For MIG, you can turn it up to aid with welding on
open gaps, out-of-position work or for use with 100% CO2or
75% Ar / 25% CO2.

Pulsed MIG
• Varies weld current between peak (high heat) and background (low heat) current to provide
better control of heat input.
• Reduces warping and burnthrough on thin materials.
• Enables in-the-flat, horizontal, vertical up, or overhead welding without a slag system. It can be
used in hard automation, robotic, and semiautomatic applications.
• Optimized GMAW-P waveforms are available to use on aluminum, carbon steel, high strength
low alloy steel, stainless steel, and nickel alloys.
For more information see Nextweld®Document NX-2.70
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.
For more information see Nextweld®Document NX-2.10
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.
• Improved MIG welding performance, including low spatter, very uniform, consistent bead wetting
and controlled penetration.
• Great for low voltage applications on thin steel and stainless steel material less than
20 gauge (0.7 mm).
• Delivers excellent arc characteristics on aluminum and other alloys such as silicon bronze and
nickel alloys.
For more information see Nextweld®Document NX-2.60
• Displays gas, mode and wire size for easy setting and monitoring.
• Eight memories to quickly switch between weld modes.
