ELENA® II

The ELENA® type II longitudinal seam welder (bench type seam welder) is a universal machine for all electric arc welding methods with or without wire. Well over 300 of these machines have been built so far and ongoing further development guarantees a mature machine concept.

Depending on machine model and welding fittings, welding of metal thicknesses from 0.15 mm to 10 mm is possible.

Standard series with maximum welding length from 600 – 4100 mm.

ELENA® II longitudinal seam welders are characterised by:

  • self-adjusting, individual clamping fingers with a point bearing.
  • pneumatic clamping motion (separate at front and rear).
  • clamping cycle with intermediate clamping stage for fast, gap-free insertion of thin material with no overlap.
  • cooled welding underlay bar / backing bar, simple-to-replace, design according to welding task e.g. geometry, groove form, root shielding gas, material etc.
  • automatic mandrel latch.
  • constant light arc length due to special carriage.
  • ergonomically designed control unit.
  • user-friendly Siemens machine control with touchscreen.
  • highest quality machine components (Festo, SMC, Siemens, Franke, IGUS...).
  • robust, welded machine body suitable for transportation by forklift or crane.
  • comprehensive instruction manual.
  • execution and documentation as per 2006/42/EC Machine Directive.
