I built a pneumatic can crusher, but I wasn't satisfied with with just crushing it, I wanted to flatten them. So I put it it on a lever, it has ~2.4 mechanical advantage. So it goes from ~160lbs from the cylinder to about 400lbs on the "squishy plate".
Unfortunately, I was a little too hardcore, after a few tests, it managed to bend the entire base. Once I can get a some thicker metal I will put it back together.
Why do this? Because I have a tiny furnace and a mountain of cans that I melt down and cast into random shit.
Up or down? I'm still learning and trying to figure out the feed.
Also, how did you know it's the feed? What should I be looking for?
Feeder down or volts up. But I see your welder is Harbor Freight so that may be the best you can get although I have the HF Vulcan that has infinitely adjustable speed and volts. I assume you are using fluxcore wire? And the reason I say feed adjustment is too many bbs
