Yaskawa’s new robot-based spot welding cell is a holistic approach to spot welding, one that focuses on solving

the gun body, a transformer and the motor. This offers maximum simplicity and ease of maintenance and connect- ing cables are routed to ensure better rotation of the wrist of the robot. The lightweight system offers lower energy consumption and the guns can be mounted onto robots with lower carrying capacity. The guns are easy to install and maintain and offer more standardisation with wider range of customisation options. Nut-welding machine The nut-welding machine is a new ad- dition designed and manufactured by Yaskawa to enable all of the necessary welding to be completed in this single spot welding cell. The unit can be attached to the right or left of the machine, depending on needs, with a dedicated handling robot (MH5) attached to the side structure. A vibrating servicing cabinet conveys nuts, bushes or pins to the handling robot. When in position, these can be picked up by the handling robot, which places them in position on the part. The servomotor then brings the nut- welding tool into contact with the item

problems rather than supplying individually branded products. Use the SnapScan QR code to access an excellent online video.

Yaskawa’s MotorGun software features: easy set up to configure communication with the welding timer; easy calibration, with a dedicated calibration page for the gun and motor; and self-learning functions.

and, like spot welding, through pressure and current flow the nut, bush or pin is welded onto the sheet metal part. Yaskawa’s new high-speed robot- based spot welding cell comes com- plete with its power sources in a weld- ing cabinet and Yaskawa’s MotorGun communication software for controlling the weld timers and gun motors. This guarantees high quality welding due to the integration and dialogue between all of the interconnected Yaskawa systems.

able robots with lower capacities to be used. Yaskawa alsomake awide range of guns with different openings, reach and wrist mounting, to best suit the items to be welded. The non-pneumatic spot welding guns consist of only three components:
