Welding Automation by Application

Seven jobs our welding carriages and machines are sized for every day — pick yours and see the recommended model, the working conditions and real footage of the machine doing that weld.

A word about references. We are building our overseas references now, and we would rather be straight with you than invent them. Everything below describes real working conditions we size machines for every day — and the photos and videos are real, shot in our workshop and on job sites, showing the same machines we ship. Before you commit, we prove the machines a different way: a live video call from the workshop, a test weld on your material, or footage of the exact model you are considering. Once your project ships, it can be the first named case here.
