Single-head automatic cycle welding machine for 90° angle corners and corners with variable angles from 30° to 180° with down-stroking heating plate. Equipped with heated bead restrictors that can be set, during the configuration phase, in a range from 0.2 to 2 mm, SM 1LV provides for vertical clamps sliding on linear guides. The melting depth can be set to 2.5 or 3 mm and the support arms are adjustable in height. SM 1LV can be equipped with counterblocks (optional) and can process all types of standard, acrylic and coated profiles as well as large profiles (one-piece). Equipped with a quick changeover function, allows easy cleaning of the Teflon film. The operating cycle is controlled by PLC, the heating plate is controlled by digital temperature controller (it can be set to either °C or F) and the LCD allows setting the heating and welding time.
The welding bead size is controlled by heated restrictors provided with mechanical adjustment. Such devices allow varying the welding bead thickness within a range between 0.2 and 2 mm. The temperature is controlled by a digital temperature controller and can reach 50°C.
Positioning of small frames for welding the 4th corner could cause difficulties for the operator as well as abnormal stress on the frame. SM 1LV is provided with a device for limiting the stroke of the intermediate stop. It also makes use of the accurate movement of the vices for inserting the heating plate thus making it easier to handle the profile.
