I have been looking for a way to ramp up the cutting oxygen, Something like a soft start valve, or........... ?
I have found Retro plasma makes a regulator assy. with "Ease on pierce rate control ". They describe it as "The rate that cutting oxygen pressure increases during the pierce is
set by the Pierce Rate Control knob".
I can't find much info on this type of system on the net.......... Anyone familiar with this type of system?
