A CLOSER LOOK
PERFORMANCE
Exceptional Multi-Process Fabrication Welding
The Lincoln Invertec®V350-PRO inverter welder 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.
3. DC TIG GTAW
Standard Lincoln Touch-Start TIG®makes it easy to establish an arc.
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 metal-
cored applications.
The Invertec®V350-PRO features an exceptionally wide sweet spot
delivering the arc performance and finished weld quality every
operator appreciates:
• .030-1/16" (0.8-1.6 mm) solid wire
• .035-3/32" (0.9-2.4 mm) 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
®
, Outershield
®
, Metalshield
®
and UltraCore
®
Features a wide voltage range and tight voltage control optimized for
Lincoln Innershield®self-shielded flux-cored applications and for gas
shielded flux-cored Lincoln®Outershield®procedures.
6. Arc Gouging accessible from all Stick and CV Welding Modes
With a maximum 425 amps, the Invertec®V350-PRO has plenty of
power to handle a 5/16" (7.9 mm) carbon.

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. Great for
hard automation, robotic, and high production 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.
