Question about 40I cutting capacity

[atcig]

I am wondering about the cutting capacity of the 40i
On the main plasma page it says -
"Rated" Cutting Thicknesses at 220 V (110V reduces power in half)*
Mild Steel Stainless Steel Aluminum
3/4" 3/4" 3/4"


On the specifications page and in the manual it says -
Cup(assuming this should be Cut) Capacity max/severance (in.) Up to ½”.


Then under the spec grid it says
Cutting Specs:
3" Per minute @ 3/4" Steel (Severance Cut)
7" Per minute @ 1/2" Thick Steel
17" Per minute @ 1/4" Thick Steel

Just curious what it really is.

I forwarded this information to Simon for clarification and so he could correct the specifications pages affected.

Thanks - I will keep checking to find out. Another thing you might want to ask him about is the Constant/Timed air setting in the manual - I have no idea what it is trying to tell me.

its probably somewhere in the neighborhood of *max severance cut up to 1/2inch* i'm thinking 3/8 or so will be in this cutters sweet spot...

my old bluepoint was 25 amp and it would do 1/4 but you had to slow it way down and work at it..... but it was old technology too, the igbt might be different...

I don't have a longevity plasma cutter but I do have an everlast that has the constant/timed air flow switch the constant is for plasma cutting on cnc and the timed is for manual plasma. The cut thickness I would think is right around 5/8" rated cut on steel/stainless @ 10-12ipm and 7/16" for aluminum @ 10-12ipm. Max severance is the maximum thickness that can be cut usually at 3ipm this machine is probably around 3/4" on steel/stainless and 1/2" on aluminum. If you want a really good cut with nice speed I'd say max about 1/4" steel/stainless and around 1/8 on aluminum. The piercing capacity is 5/16" on steel/stainless and aluminum 7/32. Thickness would be half of values if running on 110v. Remember the rated cut speeds are with a machine not by hand, cutting by hand for most people isn't as steady as a machine.
