I've been using 5 and 25... but the manual says 5 and 20, though... next

Bingo. Those are cutting torch settings, not for rosebud or welding
tip. Start with 5 and 5, work your way up with torch valves wide open
until the torch almost blows out, then adjust from there with the
torch valves. My Smith, Meco and Marquette torches seem to like
same presssure on both gasses, but torches do vary.
