Torch type to purchase accesories?

I purchased a powertig 225lx, or whatever the 225amp ac/dc tig is.

I was wondering what type of torch it is. I know it is water cooled. I mean what size though. For example...

Say I wanted to buy some cups for it. Would I buy cups for a PTA-20, DB-20 or WP-20 torch?

Or if I wanted to buy different collet to hold different sized tungsten. Or basically anything I wanted to buy... what torch number would I buy accessories for?

I believe the stock torch is a wp18.

Good question! I bought a pp256 and the upgraded torch. Please post the information on the torch I bought and I'll go ahead and get my consumables from Everlast for shipment with my 256.
I'm asking for a post instead of a PM so that others can do the same; order extra consumables while we're hangin' out waiting for delivery.

It's a WP-18.
