The chain files are included with the PS/3 sound files in the ZIP file you downloaded. You'll notice there are two files in the download, one a .MTH file and the other is another .ZIP file.

If you're interested in a nice soldering station, I use the Hakko-FX888D, and I highly recommend it. It's a standard in the industry and is used by countless industrial firms.
You can order the boiler board direct from MTH I believe, or you can also get it through an MTH dealer.
