It's best to try fighting it with Silver Armor or better. Use either the Musket or one of the pistols (The Undertaker is good if your world has The Crimson. Alternatively, any decent bow will work pretty well with at least 200 arrows or so, to ensure you don't run out.

Build an arena with rows of platforms 5 blocks apart (i.e., the highest you can reach from each level to place the platforms) and add enough light to see by. Three or four levels should be enough, and make it at least 50-100 blocks wide so you have a good amount of room to move in.

When you first summon him, he will be at a random point in his attack cycle. Generally speaking, he'll summon two or three minions before charging, sometimes less. You can shoot the minions while damaging him if you just keep shooting towards the centre of his eye (that's where they appear) -- piercing ammo is good, but not necessary. When he starts charging, use the platforms to evade him and not take too much damage. Try to keep shooting him while he's charging as much as you can. Refocus aiming on the centre of the Eye when after his third charge (he'll be summoning minions again).

When you get to the second stage, you need to be more mobile to avoid getting hit. He'll move closer and his charges will be faster. This doe showever mean he takes a bit longer to 'recover' after each charge. Keep evading and shooting him, and when he's charging, make sure to account for the movement as best you can so most of your shots land.

Good luck.
