Substantial Output. Smart Performance.
Rugged Reliability.

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
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

Advantage Lincoln

• Features full remote and multi-process capability – stick,
Touch-Start TIG

• 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.

• 88% efficiency with a high 95% power factor – the V450-PRO
inverter platform helps you dramatically lower energy consumption
to pocket real savings.

• Add the Advanced Process Panel Kit for access to Pulsed MIG
and a host of Lincoln Nextweld
allow you to tailor the arc, including: Pulse-on-Pulse®, Power Mode
and Waveform Control Technology®.

• Standard Controls include:
– 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.

PERFORMANCE

Exceptional Multi-Process Fabrication Welding

The Lincoln Invertec®inverter platform enables strong multi-process
welding performance with optimized arc characteristics for
each process.

• Fast arc response yields tight output control:
– More consistent bead appearance
– Smooth arc action
– Easy to follow puddle control

Five Welding Process Modes

1. CC-Stick Soft

Intended for low hydrogen stick applications.

Use to obtain outstanding E7018 performance for a variety of
construction and fabrication applications.

2. CC-Stick Crisp

Delivers a crisp shorting response optimized for cellulosic
(E6010) electrodes.

Stick

3. TIG GTAW

Standard Lincoln Touch-Start TIG®makes it easy to establish an arc
while minimizing tungsten contamination.

Add the optional TIG Module for touch-less high frequency starting.

4. CV-Wire

Intended for use for most MIG, and gas-shielded flux-cored or metal­cored applications.

The V450-PRO features an exceptionally wide sweet spot
delivering the arc performance and finished weld quality every
operator appreciates:

• .030"-1/16" solid wire

• .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

CV-Wire

Arc Gouging accessible from all Stick and CV Welding Modes –
With a maximum 570 amps, the V450-PRO has plenty of power to
handle a 3/8" (9.5 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-cir­cuit 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.

• 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.

• Uses high-speed regulation of output power to deliver extremely fast response to changes in the
arc, for example, when using a whip technique.

®

aids

• 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

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.
