CRX Tack Function with Wrist Buttons

In this Tech Short, we will walk through the process of creating a manual tack welding program using FANUC robot wrist buttons. The focus is on giving you a practical, repeatable method for enabling quick tack weld execution directly from the robot, whether you are programming or operating on the floor. We will cover the full workflow from building a no motion program to configuring logic and tying everything together with wrist button inputs, so you can streamline your welding setup and reduce unnecessary complexity.

We begin by creating a dedicated tack program that operates without motion. From there, we will layer in the essential logic that allows the robot to manage weld behavior safely and consistently. This includes setting override values, triggering arc start and weld end functions, and ensuring proper conditions are in place to avoid common welding errors. As we move forward, we will also walk through how to configure wrist buttons so that executing a tack weld becomes as simple as pressing a button on the robot.

By the end, we will connect everything together during execution, showing how the program responds to operator input and maintains control during the welding cycle. This approach allows for greater flexibility and control when performing manual tacking operations.

Requirements

• Access to a FANUC robot with welding capabilities
• Familiarity with the teach pendant interface
• A defined weld procedure and schedule
• Configured robot inputs available for use
• Proper permissions to create and edit programs

What You Will Learn

• How to create a no motion program for manual operations
• How to apply program logic that supports welding requirements
• Why override settings are important for error prevention
• How to integrate arc start and weld end commands into your program
• How to configure wrist buttons to trigger robot inputs
• How to execute a tack weld manually using programmed logic

This overview is designed to give you a strong foundation while keeping the implementation approachable. We will highlight key steps and decisions so you can adapt the process to your specific application. If you are looking to improve efficiency and gain more control over manual tack welding, this walkthrough will help you get there with confidence.
