This device through the control of a pneumatic system, on the
welding strength were increased strength of welding processing
mode, guarantee in different environmental conditions of the
welding strength optimum, and through digital quantizing parameters
adjustment.At the same time as the welding finished surface
directly clean finish, no hook knife and tool cutting hook groove,
welding the contact area increases by *0%**0%.Integrated these two
improvements, welding strength is much better than ordinary windows
welding equipment.
