The Power Wave® 300C Advanced Process Welder features best-in-class performance as the industry’s only true 300 Amp, 100% duty cycle, all-process machine.

From technical training to industrial fabrication, Lincoln Electric is introducing an all-new industrial 300 Amp, Do-Everything Power Wave. Packed with all of the performance and leading-edge technology you expect from a Power Wave system, now completely revamped to take the industrial “all-in-one” class of welders to the next level.


  • Best-in-Class Performance - Industry’s only true 300 Amp, 100% Duty Cycle, All- Process Machine.
  • All-Process Versatility - SMAW, GTAW, GMAW, FCAW, CAG processes
  • Advanced Connectivity and Control - All Power Wave systems come standard with access to Lincoln Electric Power Wave Manager and Lincoln Electric Checkpoint® Production Monitoring allowing for advanced remote configuration, process control, and quality assurance.
  • Patented PowerConnect® Technology - Automatically adjusts to input power from 200-600V, 50 or 60 Hz, single phase or three phase. Welding output remains constant through the entire input voltage range.
  • Tribrid® Power Module - Exceptional welding performance with high power factor and efficiency.
  • Optional 115V (10A) AC Duplex Auxiliary Power Receptacle - Features Surge Blocker™ Technology to ensure simultaneous welding performance is not compromised by high starting current devices such as grinders (typically requiring 60A or more peak surge current).
  • Ready-to-Run - Design features for simple and straightforward operation, including cable management hooks, integrated cart with tilting bottle rack, and Twist-Mate™ TIG connection and gas solenoid.
  • Smart Fan Operation - Only runs when needed to minimize noise and energy consumption.

    SMAW (Optional on VRTEX® Mobile)

    • E6010 (Fleetweld®® 5P+)
    • E7018 (Excalibur® 7018)
    • E6013 (Fleetweld® 37)


    • Short Arc (.035” SuperArc® L-56)
    • Axial Spray (.045” SuperArc® L-56)
    • Pulse (.045” SuperArc® L-56)
    • STT® Surface Tension Transfer® (.045” SuperArc® L-56)


    • Gas-shielded .045 “ (UltraCore® 71A85)
    • Self-Shielded 5/64” (Innershield® NR-232)

    • The VRTEX® system requires a space of 8’ L x 8’ D x 8’ H (2.4 m x 2.4 m x 2.4 m).
    • When operating multiple units in one location, alternate between standard and alternate frequency systems (unique part numbers are identified).
    • The VRTEX® system is not designed for operation in harsh environments. Recommendations are listed in the instruction manual.
    • Avoid magnetic fields, conductive and high frequency objects and processes.
    • An uninterruptible power supply (UPS) may be required for protection of the system from power irregularities and/or disruptions
