The UNIROOF AT/ST automatic welder is your versatile partner for welding single-ply membranes on flat or pitched roofs (up to 30°). With its sleek design and construction, as well as its movable transport axle, this new robot enables you to effortlessly weld close to the edge, at or on the parapet and easily in narrow spaces. UNIROOF shines with its ergonomic handling and the direct-driven, maintenance-free pressure wheel. This new class of UNIROOF welders—available in both 230V and 120V models—provides users with higher contact pressure than its award-winning predecessor.
