ERGO Automatic Seam Welders

TIG / MIG Linear Seam Welder Systems

The ERGO longitudinal seam welders are designed to deliver high levels of accuracy using linear rails. Whereas traditional seam welders use less precise rack and pinion track setups that use cam followers. The ERGO automatic seam welders use precision linear rails that are used to move the travel carriage smoothly over the clamped seam weld joint. Linear rail technology provides a quality affordable automated seam welder systems.

Linear track provides a much stronger hold and gives you the free travel with a Ergo TC-3 travel carriage. The track is machined to a 0.005-inch straightness tolerance, so that the seam will be as close to straight as possible.

  • Convenient, easy to read air module controls on front with operator buttons and lights.
  • Low voltage motors for safety.
  • One primary power connection.
  • Simple track alignment tooling..
  • Water cooled mandrel back up bar.
  • Copper clamping fingers and back up bar.
  • MAGA-1 Single box electric control of process operator does not need to search which box and button to push or turn.
  • Foot switch activation of clamping fingers.
  • Programmable home position, travel, and weld length.
  • Low profile, easy to move unit as weld cell changes.
  • Easy move tow motor portable design seam welding system.

Our Ergonomic design principles makes the operator's job easy with this compact longitudinal seam welder. The ERGO automatic linear seam welding machines have a unique design containing a clamping finger mechanism. This provides uniform and consistent clamping hold down alignment. The water cooled mandrel feature keeps the back up bar and parts at the optimal temperature cooling the welded joint area eliminating weldment heat deformation.

The seam weld bed retractable edge alignment devices assist the operator in aligning the part over the centerline of the backup bar groove. Linear rails are mounted to the top and bottom of the fabricated track, allowing the side beam carriage to travel smoothly via four bearing blocks. The carriage travel car has a series of 3/8 inch - 6 x 2 1/2 predrilled holes, tapped to make mounting alignment tool easy.

ERGO simple air bag replacement design takes minutes. During MIG (GMAW) welding process some weld splatter in the seamer bed area  will find openings over time. UV light and weld spatter from the arc welding process eventually requires the air bags replacement. The airbags can take hours to replace on other brands. The ERGO seamer's bladder takes minutes to replace damaged air bags and start seam welding production again.
