Invertec®V450-PRO

PHASE

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

and other arc performance Lincoln Nextweld 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.

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.

J) Output Amps or Output Voltage Control Knob K) Large, bright, easy to read Volt Meter

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.
