Moguera tends to run out of energy very fast. It is a good idea to have Moguera shut down and recharge a few times before fighting again, but do the following for a quick win. While on treads and moving, fire some missiles and purple beams to do a ttle damage. Then, hold X and do the isomorphic drill and tap B and any weapon attacks. After that, recharge and repeat the process. After some time you can toy around with his way of combo attacks and pattern. He does best with patterned attacks.
