Rail Bull 2|All Position Welding Tractor
Automated welding and cutting tractor – Rail Bull 2 t can be custom configured for a variety of welding, thermal cutting and gouging applications on flat or curved plate, tube and pipe. It’s suitable for all welding positions on both ferromagnetic and non-ferromagnetic materials. Rail bull 2 is best choice for your cutting and welding automation process.
  Description






Primary features and benefits:

 
 
  • 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
  • Limit switch stops the arc and travels the tractor to the initial position
  • Minimum curvature radius required is 5 m (16 ft) for the semi-flexible track
  • With ring tracks diameters from 200 mm OD up to 3000 mm OD are allowed
  • 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 3 m/min makes plasma cutting available

Rail Bull 2 system 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 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 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 operator from heat and fumes
