The footage of them in full face obscuring costumes, along with the mecha, is mostly straight from various Japanese shows, overdubbed into English. The US production company got Japan to shoot a little bit of extra content when Mighty Morphin Power Rangers became a smash hit, before they started rotating to other Japanese series to take footage from. You can make more money off of the toys, anyway, if you have new action figures and mechs every year.
Wasn’t it just an American carbon copy of a Japanese show?

Redubbed I think, at least in costumes.
