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.

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.

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 |
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.
