Cutting small holes - consumable life expectency

I am getting ready to cut several thousand small brackets using 11 gauge mild steel. Each bracket is 1.75" x 1.75" and includes 4- .25" holes each. Here is what I am running…

Crossfire Pro
PrimeWeld Cut60
Fusion 360 - FireControl

Does anyone have advise on pierce height/delay, cut height, cut rate etc.? What should I expect for consumable life?
