Quiet, precise, self-propelled welding machine equipped with a "hot wedge" for joining materials in coated and foil used, among others in the production of billboard, inflatable balloon and tarpaulin. Available in a version for 20 or 30 mm wide welding in the technology of direct contact of the welded material with the heated heating element. Unlike welders with a hot air nozzle, Uniplan Wedge is characterized by low power consumption, does not emit smoke during welding and eliminates the possibility of blowing material in "difficult to weld". Leister Uniplan Wedge allows you to make popular types in the weld: overlap, tunnels and edges under the eyelets. Uniplan Wedge has an automatic start system and electronic display for precise parameter adjustment in temperature and welding speed. In addition, the device can be equipped with a laser pointer for easy guidance and a modification kit for connecting with acrylic tape based on thermoactive glue.
