Rail Bull 2 – All Position Welding Tractor

• Fully modular mechanized travel tractor 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 200 mm (8”) OD up to 3 m (10 ft) OD
• Hi-Flex tracks on diameters from 1500 mm (59”) OD upwards
• Custom rolled tracks on diameters from 3 m (10 ft) OD up to 10 m (32 ft) OD
• Semi-flexible tracks can be flexed to minimum radius of 5 m (16 ft) 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 3 m/min makes plasma cutting available

1. Easy to upgrade modular design
2. Continuous and programmable path of stitch welds (weld length, space between welds, backweld length, crater fill time)
3. Linear torch oscillator to produce weave welds
4. Three modes of automatic seam tracking (vertically, horizontally and both)
5. Limit switch stops the arc and travels the tractor to the initial position
6. Hand-held ergonomic control pendant (3 m cable included) with magnetic adhesion provides firm grip on ferromagnetic materials
7. 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
8. Intuitive software with user-friendly interface
9. Automatic Arc on/off initiates welding and travel simultaneously
10. Rack and pinion drive
11. Convenient external 230-V, 115-V, or 42-V power supply
12. Closed-loop position control system based on electric motor with encoder, ensures increased accuracy of speed
13. and position
14. Consistent heat input reduces distortion
15. Reduces wasted filler metal – eliminates over welding
16. Quick-clamping torch holder mechanism for different types of MIG/MAG torches with diameters of 16-22 mm
17. (0.63-0.87”); up to 35 mm (1.38”) option
18. Precise torch adjustment
19. Improves working environment – removes operator from heat and fumes
