5 spot welding safety tips
Our lab gets a lot of calls asking us how to safely use resistance welding equipment, so I thought I would write a few words about the most common issues that affect safety. Before I begin, let me first say that all resistance welding equipment should only be used by qualified and trained personnel for its intended purpose.
