Wire-Balm PROTEC WLS04.5

PROTEC WLS04.5 for wire coating

Contact lubricant for coating of wire electrodes in wire production

  • PROTEC WLS04.5 is the latest generation of a contact lubricant for coating of wire electrodes as a finish during the production process
  • Suitable for all types of wire, bare and copper-plated, solid or tubular wire; not compliant with aluminium
  • Removes drawing agent residue and cleans the wire (fine cleaning)
  • Ensures improved friction coefficient and smoother feeding
  • Improves current transfer in the contact tip, reduces energy loss, avoids micro arcs
  • Forms a protective layer against corrosion and oxidation


  • Perfect precision layer coil winding and protected wire finish
  • Stable process even with difficult feeding radius
  • Stable arc with proper ignition


  • Clean wire with optimum feeding characteristics
  • Process safety in processing / welding:
    − Improved layered coiling and barrel finish in the factory
    − stable arc with optimised ignition and reduced spatter output in the welding process

Customer benefits

  • Increased productivity and quality in wire production
  • Increased processing productivity (welding)
  • Longer service life of wear parts, e.g. liner and contact tip (no micro arcs)


Coat wire with PROTEC WLS04.5 after last draw (at the end of the drawing line; preferred over rewinding due to lower speed).
We recommend tandem process: apply slightly excessive amount, wipe off thoroughly so that a minimal, fully covering and even film remains.
