multiweld3

Multi Weld is our special designed machine model for multiple stations on one frame.
The base model is delivered with one welding station but it is possible to expand up to four welding stations.
The welding stations can be delivered with shared- or individual welding circuits.
The machine design also gives the opportunity to feed material straight through the machine to a bin or pallet outside the robot cell.
Of course Lerocon quality options also is available for the Multi Weld machines.

  • Bosch 36kA or 54kA welding inverter with 256 programs.
  • 130kVA transformer.
  • 95 mm pneumatic stroke of the welding cylinder.
  • Lerocon HMI operating panel with recipe management.
  • (Swedish or English version)
  • Beckhoff PLC.
  • Cylinder Packages in red anodized aluminum.
  • Prepared for Dengensha nut feeder.
  • Strong solid steel frame with 500, 700 or 1000 mm working depth.
  • Lerocon GPR Weld Tool - Welding tool with "guide pin retraction" for faster repositioning and quality assurance.
  • Lerocon HMS – Height measuring system with high accuracy.
  • Easy setup in Lerocon HMI for control of height of the materials before welding.
  • Lerocon MHA – Mechanical height adjustment of the start position for the welding cylinder.
  • Lerocon GPM – Guide pin measuring system with high accuracy.
  • Easy setup in Lerocon HMI. Note, this options require Lerocon GPR Weld Tool. Checks that the guide pin is in correct position before welding.
  • Lerocon FMS – Force measuring system.
  • AC Welding Circuit
  • A.P.E.S – Automatic Part Evacuation System

Lerocon AB is a privately owned company, based in Gislaved since its inception in 2003. Initially our focus was on service and support of special machines and resistance welding machines. Fairly soon we saw the need for a custom automation nut welding machine and began to produce the first models for the Lerocon Multi Weld.
