Our trademarks

Please choose your language:

In the following, we wish to introduce to you our different trademarks and what is behind it:


WI-FORCE®

stands for power… and our machines do have it!

We use unique oil hydraulics:

  • Oil accumulation system for hydraulic follow-up pressure
  • Mechanically triggered pressure relief
  • Pressure setting valve enables precise pressure control
  • Hydraulic pump only running if pressure is built-up, therefore it is no permanent running pump; thus it has a long life and saves energy

Our roller stands for professional use are bearing this trademark as well.


WI-HEAT®

stands for heat resp. high temperatures; these are the working conditions of our heating elements.

You will recognize their quality by:

  • very light weight!
  • multiple wear-resistant coating
  • thermal separation of heating plate and handle
  • integrated control unit
  • very low energy consumption
  • more exact temperature distribution than required by DVS 2208 part 1
  • easily replaceable heating plate
  • cartridge heating elements containing up to eight individual temperature regulating zones (starting from WIDOS 8000)


Our precise thermometers are bearing this trademark as well.


WI-PRECISION®

stands for precision; not only meant here is the high-quality machine construction but also the precision in using / operating it.

The basic machines of our butt welders for the construction site are unique because of:

  • low weight
  • removable fourth ring including frame → flexibility under narrow conditions
  • very wear-resistant spindles / trapezoid threads
  • hardened and hard-chrome plated piston rods
  • special seals enable extremely smooth running
  • guiding in pipe axis center (WIDOS invention)
  • tear-off device for the heating element prevents sticking to the pipe after heating
  • all colored parts are plastic-coated, other parts are galvanized
  • hydraulic lines plunged into the clamping ring; flat sealing; simple-to-clean couplings
  • hydraulics may be vented easily at the machine


WI-ENERGY®

stands for energy; an electro socket welding possibly needs lots of it!

Our ESI 4000 electro socket welders are therefore capable to supply a lot of energy over a long period of time!

  • almost all common electro fittings may be welded!
  • efficient cooling for permanent operation; no flexible cooler parts like e.g. fan 
  • traceability
  • all standard functions for the universal application
  • protected by steel frame (made of stainless steel)
  • very easy handling
  • electrical security
  • double data storage: on internal memory and on SD card ("dual store system")
  • lightweight by inverter technology
  • all inner lying parts are protected against dust and splash water

WI-FIX®

stands for easy and fast!

Our reducer inserts are distinctive:

  • generally each diameter is covered by a clamping shell for more precise pipe clamping
  • in small, large or extra large version
  • two mounting positions: in the center or on the outside for especially short pipe pieces
