Mini Spider – Welding carriage on R.O.B Girder/bridge beam fillet welding
MINI SPIDER – The welding carriage mini spider is dedicated to an end-to-end welding application. R.O.B railway bridges/bridge beams are the best suitable jobs for mini spider in which stiffeners MIG welding has to be done from one end to the other end.
Key features:-
- 4-wheel drive system with magnetic traction and a feedback loop provides highly efficient speed stabilization.
- Constant, continuous and repeatable travel speed enables weld bead geometry that is exact to the required specifications, thus reducing costly over welding and substantially decreasing filler metal usage.
- An optional power supply can be used to plug the carriage into a 110–240 V power source.
- Compact and lightweight design to weld in narrow spaces
- Convenient 18 V DC battery supply (the same battery for both Mini Spider and Gecko Battery)
- Torch placement on either side
- Welding edge to edge
- Closed-loop speed control system based on electric motor with encoder – ensures increased speed accuracy
- Consistent heat input reduces distortion
- Reduces wasted filler metal – eliminates over welding
- Digital LED display for presetting of travel speed and diagnostic messages
- Low-battery indicator
- Built-in guide rollers
