What pierce height for different materials???

[2fst4u]

At what height do most people pierce at. Can't seem to find any info on Hypertherm site. I have a 1650 with the tm100 machine torch. I use the optimum speeds/amps etc. that they recommend but they don't tell you a pierce height. I cut the following,

Mild steel

3/4
1/2
3/8
1/4
10 ga.
11 ga.
12 ga.
14 ga
16 ga

Aluminum

1/2
1/4
1/8

S.S.

1/2
3/8
1/4
10 ga
12 ga
14 ga
16 ga

Thanks,

Tony

Pierce hight is usually double of cut hight.
