Receptacle change question

I have a plug wired for an electric dryer, with the typical four prong plug, on a 30 amp breaker. I would like to replace it with a different receptacle that will fit a 240volt heater, which has a three prong plug. This is for a garage, for some reason the prior owner had a dryer outlet in there, maybe it was for a welder, would that typically have the same plug as a dryer?

A welder usually has a 6-50 and a dryer typically uses a 14-30. If a welder only needs 30A then a 14-30 may have been used without connecting the neutral. A 240V 30A heater should use a 6-30 leaving the neutral wire capped and not used in the outlet box.
