There is a "pot" that can be turned to change current. I'm pretty sure voltage will stay at 12V regardless of current.

Look just to the left of R2 , the first component on the left is the pot. I would suggest using a multimeter/ammeter to check the current while turning the pot. Can't determine output current safely otherwise...

Hope this helps
