Lizard Programmable Welding Carriage

LIZARD is a portable, programmable, trackless welding tractor designed to produce consistently high-quality welds. It can be programmed in continuous or stitch welding modes. Welder-friendly two-function buttons enable storage and reproduction of up to 40 different welding programs for various joint configurations and multi-pass, multi-layer welds. Constant, continuous, and repeatable travel speed enables weld bead geometry that is exact to the required specifications, thus reducing costly over welding and decreasing filler metal usage, substantially.

LIZARD is capable of producing weave welds by means of an optional pendulum oscillator. The oscillator allows for precise control of weave width, weave speed, and left/right side wall dwell and is particularly useful for vertical welding.

  • Up to 40 complete programs may be stored in non-volatile memory to repeat optimum weld procedures
  • Multifunctional LCD and 2-function buttons for programming selected welding patterns and parameters such as weld length, the distance between welds, reverse fill, crater fill time, and others
  • The closed-loop speed control system stabilizes travel speed, enabling uniform heat input to produce consistently high-quality welds
  • Lizard travels at full speed between stitches, which saves valuable welding time.
  • The optional torch oscillator produces weave welds
  • 4-wheel drive magnetic traction permits out-of-position use
  • Compact, lightweight design with a durable aluminum cast housing
  • Convenient Power Supply 115–230 V, 50–60 Hz or 42 V, 50–60 Hz
  • 3 years of warranty

description

Vertical-up welding with PROMOTECH LIZARD on a 16 mm P355GH heat exchanger shell. Welding heat exchanger shell sections requires more than just depositing metal. Full penetration, consistent travel speed, stable vertical-up welding, and repeatable weld quality are essential to ensure the integrity of the final structure.

With the LIZARD welding tractor and weave oscillator, these critical process parameters remain under control throughout the entire weld.

Project details:
Material: P355GH boiler steel
Plate thickness: 16 mm
Joint preparation: asymmetrical X-bevel
Welding position: PF (vertical up)
Welding solution: PROMOTECH LIZARD welding tractor with optional weave oscillator

The process included:
✔ Root pass on a ceramic backing strip
✔ Fill passes
✔ External cap pass
✔ Internal finishing cap pass
The cap pass was completed at a travel speed of 14.5 cm/min, while maintaining excellent weld quality and full process control.

A 36mm wide flexible track ensured stable tractor guidance and highly repeatable welding parameters throughout the process.
