To turn the opinion on amps a different direction not on cut quality but effects on equipment.
Is it better to cut slower at low amps or faster at higher? Leave time out of the equation. Will a set of consumables say 45 amp set last longer or shorter than a set of 65 amp consumables cutting the same material and parts?
I normally do my long cuts with the copper plus electrodes and lately running at 65 amps.
Today I ran the standard hypertherm electrode and a 45 amp nozzle.
These consumables cut 433 washers and one square 24x24. There is 3 hours and one minute torch on arc time and 1300 pierces.
They are well used and earned my respect. I never try to run them til they blow.
This is the 433 washer the best and worse side as far as taper
