ABSTRACT:
Welding equipment for plastic plates and the like includes a support. First and second longitudinally extending spaced parallel clamping tables are movably mounted to the support so that the tables may be moved towards and away from each other. First and second clamping beams are provided. Each beam overlies one of the tables and is movable therewith and each beam has a first and portion pivotally associated with one of the tables. A lock system extends from each of the beams and cooperates with another lock system associated with the support. The lock systems permit the beams to be independently pivoted relative to the support. A heated blade is movably positionable between the tables.
