Abstract
A plurality of sets of clampable jaws are positioned on cooperating pairs of sub-towers, one of each pair moves along the x-axis and one along the y-axis. In using the apparatus, fenestration product frame members which have been precisely cut to a desired cut length are placed in the clampable jaws. The frame members are positioned so that their ends are in non-touching proximity to radiant heater and a limited length of the ends of the frame members melted and then quickly brought into contact to effect welding of the joints. The precision placement of the precisely cut frame members results in a low-flash window frame.
