3 General Product Data

The DEMTECH Services, Inc. Pro-Wedge VM-20 Geo-Membrane Wedge Welder,
hereinafter referred to as the Pro-Wedge or welder, dramatically speeds the welding of
plastic sheet materials through the use of its wedge heating elements and multiple
pressure roller design. These features combined with state-of-the-art electrical and
electronics controls and an easy to use User Interface (UI) makes performing welding
tasks very efficient. The semi-automated operation of the welder eliminates cumbersome
setup and speeds up processing time while providing a very rugged and reliable welder.
The enclosed controller sub-system is easy to maintain. You can be assured the Pro-
Wedge has been built using the highest quality materials available which include Billet
Aluminum and ground and hardened steel. DEMTECH Services, Inc. strives to make our
welders easy to use and built to last. Just like all other DEMTECH Services, Inc.
products, even a first time user will be productive in minutes.
