Powerpack arcwelding and RW 5.16 - application templates missing

I wanted to use powerpack arcwelding in station whis has RW 5.16. When I try to add weld commands in path view, weld instructions are out of use. It cant use those because application templates are missing. What is the right way and location to add those arc application templates in this case using RW5? Station which I use is based on my clients backup, it has option Arc 633-1.
