These materials are for a platinum pendant and they include wire made of a platinum iridium alloy. This article covers a manufacturing method using tack-welding technology for making the wire setting for a pendant with a movable bail.
Tack-, fusion- and pulse-arc equipment settings will differ and are based upon the volume, amount of contact and alloy of the material you are working with. Practicing using like materials will give you a parameter for the settings required for your application. Keep a record of settings and tasks for future reference.
