This wasn't one of the best 80's toy-related cartoons, mainly because the toys weren't that good and the show was weird. From what I remember, a team of 3 guys had adventures in the earth's core fighting monsters. They had these huge armored suits that they had to put on in order to go there, of course. I think one guy's suit had big claws on it, another had drills... things you'd need in order to get around in the core of the earth.
