Rail Bull 2



Part #:





The Rail Bull 2 is a track welding carriage designed to produce butt and fillet welds with or without oscillation.

Price for machine only. Track sold separately.

The carriage can work in PA (flat), PB (horizontal vertical), PC (horizontal), PF (vertical up), and PG (vertical down) welding positions.
Rail Bull 2 moves along either rigid or semi-flexible track. Both types of tracks are fixed to flat or curved ferromagnetic surfaces by means of dual magnetic units. The minimum curvature radius required is 5m (16 ft).

Rail Bull 2 can work in all welding positions on both ferromagnetic and non-ferromagnetic materials by using rack and pinion drive and various tracks equipped with magnetic or vacuum units.

  • Fully modular mechanized travel carriage can be custom configured for a variety of welding, thermal cutting and gouging applications on 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.
  • Suitable for variety of circumferential and irregular surface applications down to minimum radius of 100 mm (4”)
    – Ring tracks on diameters from 200mm OD up to 3m OD
    – Custom rolled tracks on diameters from 3m OD up to 10m OD
    – Semi-flexible tracks can be flexed to minimum radius of 5m without permanent deformation
  • Ergonomic remote control pendant with simple and easy to find control knobs makes adjustments possible without lifting of the operators welding hood
  • Magnetic adhesion of the pendant provides 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
  • Rail Bull 2 produces consistent high quality welds and cuts in a fraction of the time required by manual operations
  • High speed up to 3m/min makes plasma cutting available

  • 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 (vertical, horizontal 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 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 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 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 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 operator from heat and fumes
