How to Avoid Dead Shorts using Simple Search

In this video, we will go over how to avoid dead shorts when using simple search in a robotic welding application. We will walk through the practical steps needed to improve arc start reliability and reduce common issues that can impact weld quality. This session is led by an applications engineer from FANUC America and focuses on a straightforward technique that can be applied directly within your existing workflow.

We will begin by reviewing what a dead short is and why it occurs during the welding process. From there, we will explore how simple search positions the robot at the joint intersection and how that positioning can unintentionally lead to the wire remaining in contact with the workpiece. This condition can create problems such as failed arc starts or excessive expulsion, both of which can affect consistency and efficiency.

As we continue, we will go over a simple yet effective solution that helps prevent this issue. We will introduce the use of a teach pendant instruction combined with a backward wire feed output. This adjustment allows us to retract the wire slightly after the search is completed, helping to achieve the proper stick out before initiating the arc. The goal is to create a cleaner and more stable arc start without adding unnecessary complexity to the program.

This overview will keep things practical and focused so you can clearly understand how to apply this technique in real scenarios. If you are already familiar with simple search fundamentals, this video will build on that knowledge and show you how to refine your process for better results.

Requirements:

• Basic understanding of simple search functionality
• Familiarity with robotic welding operations and arc start procedures
• Access to teach pendant programming and digital outputs
• Prior exposure to the simple search icon tech short is recommended

What We Will Learn:

• What causes a dead short in welding applications
• Why wire contact before arc start leads to performance issues
• How simple search positioning can contribute to dead shorts
• How to use backward wire feed to achieve proper stick out
• Practical steps to improve arc start reliability and weld quality

This video is ideal for anyone looking to fine tune their welding process and reduce common startup issues while keeping programming simple and effective.
