Manufacturer Reviews

By: Kevin
Our company needed to upgrade in order to compete in the Aluminum Welding industry, the Dynasty 400 is an amazing purchase that is reliable and dependable. It has a lot of new high tech features that allow the welder to dial in and control the weld bead where we struggled with our older machines. We bought three machines recently and may purchase more soon!
