The fast automatic spot welding machine type SP-3/2×103/AC is designed to weld a detail in 10 points. The operator places the detail in the holder, from where it is picked up by the gripper and transferred to the welding zone, the electrode set performs ten spot welds. After welding, the finished parts are transported by belt conveyor to the quality control and unloading area. The entire process takes only 12 seconds, which ensures an efficiency of 300 details per hour.

A Siemens PLC master controller with an HMI control panel and a TECNA welding parameter controller were used to control the device. Optoelectronic safety curtains are responsible for the operator’s safety.
