Measure the wiper to gnd with an ohm meter. It may have an internal gnd connection. If not gnd it.

Yes, it is usually connected without being soldered.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Sometimes it is a ring riveted to the middle pin (or soldered) that goes around the shaft so when mounted it provides the grounding.
