Old welder vs new welder on a tube job last week

I ran a Lincoln 350MP for 6 years and thought it was fine. Then I borrowed a buddy's Miller 350P for a stainless tube job last Thursday and my weld time dropped by 40% on the same material. The pulse settings were way smoother and I didn't have to fight spatter. Now I'm wondering if the old machine was holding me back or if I just got too comfortable with crappy settings. Anyone else switch brands and see a big difference?

It's funny you mention that because I've noticed it everywhere not just with welders. Same thing happened when I switched from an old Dewalt drill to a Milwaukee Fuel. The tool wasn't bad, I just didn't know what I was missing until I tried something better. Comfort zones ruin your perspective on what good actually looks like.

Ngl, you're not wrong about comfort zones but that drill comparison is a bit off. Milwaukee Fuel is a brushless motor and Dewalt drills from the same era are also brushless so it's more about ergonomics and battery platform than a huge leap in tech. With welders, the Miller 350P has a different pulse algorithm than the Lincoln 350MP - it's not just a settings thing, the waveform control is actually different on the Miller. That's why you saw such a big jump on stainless tube where pulse tuning really matters.
