The difference in our shop's weld quality after switching from a 30-year-old Miller to a new Lincoln Electric machine

Honestly, we were getting a lot of porosity on our pressure vessel seams for a job in Tacoma. Our foreman finally approved a new Lincoln Electric Power Wave machine about six months ago. The bead consistency is way better now, and our X-ray rejection rate dropped from like 15% to under 2%. Has anyone else seen a jump like that just from a new power source?

That 15% rejection rate on pressure vessel seams is a real gut punch, man. We had a similar fight with porosity on some pipe spools last year, and it just kills your schedule. Makes you wonder how much time and wire we all burned through on those old machines before they finally gave up.

Remember my buddy telling me @john_murphy64 how his whole crew celebrated junking their old welder.

That "gut punch" rejection rate is just proof those old welders built real skill, something drew791's buddy might regret losing.
