Gecko | Fillet Welding Carriage

Gecko / Gecko HS

Gecko is a portable fillet welder designed to produce consistent high-quality welds. Constant and repeatable travel speed enables weld bead geometry that is exact to the required specifications. Gecko HS with increased horizontal speed is suitable for both speed welding and plasma cutting.

Primary features and benefits:

  • Compact, lightweight design with durable aluminum cast housing
  • Convenient Power Supply 115–230 V, 50–60 Hz or 42 V, 50–60 Hz
  • Positive magnetic traction permits out of position use
  • Magnet on/off lever permits easy set up and adjustment on work piece
  • Maintenance free 4-wheel drive with worm gear reduction
  • Heat resistant silicone wheels
  • Quick clamping Torch Holder mechanism for different types of MIG/MAG torches with diameters of 16-22 mm (5/8” – 7/8”); optionally up to 35 mm (1-3/8”)
  • Precise torch adjustment with screw drive cross slide
  • Multifunctional LED display – presetting of travel speed, error codes information
  • Consistent heat input reduces distortion
  • Reduced wasted filler metal – eliminates over welding
  • Automatic arc on/off system initiates welding with travel, simultaneously
  • Capable of carrying and controlling 2 torches
  • Self-guiding roller arms eliminate the need for track
  • Multi-surface guiding with user-friendly adjustment of tractor position
  • Improves working environment – removes operator from heat and fumes
  • Plasma cutting possible
  • Closed loop speed control system stabilizes travel speed to reduce weld defects and costly rework

The newest improved guide arms family makes a proper welding tractor positioning even easier.

  • 7 different guide types are dedicated to various welding applications and positions
  • include a number of fixing grooves for your convenience
  • enable simpler, easier and more consistent adjustment of how guide arms stick out
  • secure proper tilting of the carriage into a direction of its movement
  • maintain a permanent contact with the workpiece
  • allow either interval or continuous guide arms adjustment

Continuous adjustment of a degree how much the guide arms stick out.

Each new guide arm has got a number of indented grooves only on one side. All types of guide arms are available in pairs of 2 pcs: right and left.

Interval adjustment of a degree how much the guide arms stick out
