Kody Wenglikowski, an applications engineer at FANUC America, provides a technical walkthrough on how to enable and use weld procedure lock functionality on FANUC robots. He explains that this feature is standard on ARC tool and LR ARC tool systems after software version 9.4.0.77. The tutorial covers the step-by-step process of enabling the feature through controlled start, navigating to ARC tool setup variables, and changing the AWS config settings. He demonstrates how to lock weld procedures, which are then indicated by red stars and become view-only until unlocked. The presentation also covers how to permanently lock procedures by disabling the change weld procedure lock variable and performing a cold start, providing users with security options for their welding configurations.
