Rail Bull 2 – All Position Welding Tractor

• 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

• 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 travael 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
