As an example I used a 600K+ Explosive Rocket launcher on him and did little damage. Once his shield is down you switch to non elemetal infinity (other weapons might be fine?) and just lay into him and try to stay alive.

All four of us used Elec weapons at first as his shield needs to come down before you can hurt him. The mechro spawns Pete and then used Deathtrap with Elec damage to occupy him. Now the crappy thing here is that by turning the handle you also release a small swarm of rats and or spiders. This washes off the green goo and stops the damage from it. The water pours out and you stand under it for a second. If you get hit with the green goo just run over and turn the red handle. The main use for the handles is turning them relewase water. Once he has spawned the red handles become active. So there is a switch to spawn him and there are also two red handles to release water. The weapon choices we all infinity pistols. All four of us had Inflamable Bees equiped (Pyros main attack is fire and the Bee prevents damage from it). This one is time consuming like Gee though.

Ok so when we first got to this guy I thought it was going to be easy.lol. This fight can be accessed after you beat the DLC (Kill Piston). This is for the second fight with Pyro Pete not the first. This is just to hlpe those who might need it for this fight. Side note: It appears you cannot farm Piston, just FYI.
