The VRTEX® Mobile simulates the GMAW (short arc, spray, pulse and STT® metal transfers) and FCAW (Self-shielded and Gas-shielded) processes in the standard system.  SMAW (E6010, E6013, and E7018) is an optional hardware and software kit.

SMAW (Optional on VRTEX® Mobile)

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

GMAW

  • 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)

FCAW

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

The VRTEX® Mobile comes with 3 welding coupons (Flat Plate, Tee Joint, Groove Joint) that can be used in limited positions.

  • Plate: Flat, Horizontal, Vertical and Overhead
  • Pipe: 2G, 5G and 6G
  • The VRTEX® Mobile supports limited positions:
  • Plate: Flat, Horizontal and Vertical
  • Push and drag GMAW techniques
  • Stringer beads
  • Weave techniques – straight, triangle and box weave

Recently released! The VRTEX® has now expanded language support for Portuguese (Brazilian) and Russian.

Input current: 4A @ 115, 2A @ 230

  • 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
