Orbital Welding System – 5G/6G MIG/MAG welding

Promotech’s carriage is dedicated to Penstock I.O/O.D welding, pipe to pipe 5G/6G welding, and pipe to flange welding.
Promotech’s carriage is suitable for a variety of circumferential and irregular surface applications down to a minimum radius of 100 mm (4 inches). Followings are the variety of tracks available with our carriage

  • Ring tracks on diameters from 200 mm (8”) O.D up to 3 m (10 ft) O.D
  • Custom rolled tracks on diameters from 3 m (10 ft) O.D up to 10 m (32 ft) O.D
  • Semi-flexible tracks can be flexed to a minimum radius of 5 m (16 ft) without permanent deformation

Primary features and benefits:

  • A fully modular mechanized travel tractor can be custom configured for a variety of welding, thermal cutting and gouging applications on a flat or curved plate, tube and pipe
  • Linear torch oscillator to produce weave welds
  • Active compensation of torch position vertically and horizontally by means of modular automatic seam tracking system
  • Programmable path of stitch welds
  • Possibility to select one limit switch preset out of three presets available.
  • Ergonomic remote control pendant with simple and easy to find control knobs makes adjustments possible without the lifting of the operator welding hood
  • Magnetic adhesion of the pendant provides a firm grip on ferromagnetic materials
  • Suitable for all welding positions on both ferromagnetic and non-ferromagnetic materials thanks to rack and pinion drive and various tracks equipped with magnetic or vacuum units
  • Promotech’s carriage produces consistently high-quality welds and cuts in a fraction of the time required by manual operations
  • High speed up to 3 m/min makes plasma cutting available

Promotech’s carriage overview

  • Easy to upgrade modular design
  • Continuous and programmable path of stitch welds (weld length, space between welds, backweld length, crater fill time)
  • Linear torch oscillator to produce weave welds
  • Three modes of automatic seam tracking (vertically, horizontally and both)
  • Limit switch stops the arc and travels the tractor to the initial position
  • Hand-held ergonomic control pendant (3 m cable included) with magnetic adhesion provides a firm grip on ferromagnetic materials
  • Multifunctional LED display with numeric representations for each motion parameter makes presetting and repeating of the optimum welding or cutting procedure simple and without guess work
  • Intuitive software with a user-friendly interface
  • Automatic Arc on/off initiates welding and travel simultaneously
  • Rack and pinion drive
  • Convenient external 230-V, 115-V, or 42-V power supply
  • Closed-loop position control system based on the electric motor with encoder ensures increased accuracy of speed
  • and position
  • Consistent heat input reduces distortion
  • Reduces wasted filler metal – eliminates over welding
  • Quick-clamping torch holder mechanism for different types of MIG/MAG torches with diameters of 16-22 mm
  • (0.63-0.87”); up to 35 mm (1.38”) option
  • Precise torch adjustment
  • Improves working environment – removes the operator from heat and fumes
