c frame pneumatic3

C-Frame Pneumatic is our most commonly used nut- and bolt welding machine for both automated and manual production.
Our unique design of the machine and welding tool offers very high flexibility and accessibility.
Together with our available options you will have functions for complete quality assurance and probably the fastest machine available on the market.

  • Bosch 36kA or 54kA welding inverter with 256 programs.
  • 130kVA transformer.
  • Triple Cylinder Package for maximum flexibility.
  • 95 mm cylinder stroke.
  • Lerocon HMI operating panel with recipe managemen (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.

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.
