Sorry to be a pain but is 550 watts good enough for a singer 111g155 max expected 5-6mm veg tan

Should be more than enough, I use a 550w (well, so they say, who knows what it actually is ) Lishui Skyrit on my Seiko and it goes through whatever I put under it with #138 thread. Of course, I do have a speed reducer fitted too.
