In this video, we walk through how to configure and manage weld procedure lock using enhanced weld procedures on a FANUC robot system. This session is led by an applications engineer from FANUC’s continuous processes group and focuses on a practical feature that helps protect critical welding parameters from unintended changes.

We will go step by step through the process of enabling weld procedure lock, starting with how to access the correct system menus and variables. We will also cover what changes to expect in the weld procedure interface once the lock is activated, and how this impacts the ability to edit welding parameters. The goal is to give a clear understanding of how to maintain consistency and control within your welding operations by using built-in system functionality.

Along the way, we will highlight the relationship between weld procedure lock and enhanced weld procedures, and how these features work together within ArcTool and LR ArcTool systems after the V9.40/P77 software release. This overview keeps things focused and actionable while leaving room to explore the full walkthrough in the complete video.


Requirements and key topics covered:

  • FANUC robot with ArcTool or LR ArcTool software version V9.40/P77 or later
  • Access to controlled start and cold start functions
  • Navigation of system menus and variables, including AWS configuration
  • Understanding of weld procedure screens on CRX systems
  • Basic familiarity with robot setup and configuration workflows

What we will learn:

  • How to enable weld procedure lock through system variables
  • Where to locate and modify the weld procedure lock setting
  • How to confirm that weld procedures are successfully locked
  • What changes occur in the user interface after locking a procedure
  • How to make a weld procedure lock permanent and how to reverse it if needed

This video is designed for users who want to improve process reliability and safeguard critical weld settings. We will give you the context and steps you need to get started, while the full session provides a complete demonstration you can follow along with.
