I think i remember you guys from the we-cim training at dynatorch (gary is my dad). Anyways, i cut mostly 14 ga cold roll stuff with 40a finecuts. My settings are as follows: setpoint= 93 Feedrate=130 My amperage on the 1250is set at about 32. You should be able to cut pretty decent with those settings if you turn down the feedrate a little(,maybe 100) and increase the setpoint to about 100. You should probably run the plasma inbetween 35-40. Give that a try, and hope for the best lol.
