The Profile arm is the one that came fitted to the TT. It was a package system. The arm is from Japan, and may be a Sumiko. I don't know what the cartridge is.
The first thing you should do is either inspect the cartridge or replace it. A Goldring cartridge would be a good match at a reasonable price.
Get a cartridge alignment tool at Turntablebasics.com and make sure that you align the cart properly.
Balance the tonearm with the cartridge installed, and then apply the tracking force and anti-skate as suggested by the cartridge mfr.
I am assuming that the TT works alright, and the belt and motor are keeping speed.
