The Mini Spider is a battery-powered welding tractor designed to produce continuous fillet welds using MIG/MAG torches. The torch can be easily swapped from one side of Mini Spider to another.

• 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.
• 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) with an optional power supply that can be used to plug the carriage into a 110–240 V power source.
• Torch placement on left or right 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
