Make sure you are preheating long enough..........
For 2" plate I have good luck with a # 4 tip (Koiki of course)
210 sec. preheat time,
1.5 sec. pierce delay,
1 1/2" pierce height,
55 to 60 psi cutting oxy pressure.
But I still cringe every time it fires!
I would love the soft start valve, I think once you get it figured out you'll be glad you took the time to do it.
Good Luck, Steve
