What does "IHS" stand for and what does it do?

I know what THC stands for… Torch height control. I believe THC keeps the same distance across the plate when you are cutting especially on warped metal. I am confused on what IHS stands for and what it does. Sry I’m learning.

Initial Height Sense

initial height sensing
It is the first action the torch z axis does when it reaches the point of the first penetration.
That is when the z axis lowers the torch…touches the metal then raises up to the right height

Wait so what’s the difference? IHS beings the torch down and brings it to a certain height, and then THC keeps the torch at that height when it’s moving across your plate of material?

You got it Pontiac…

THC will adjust and maintain the appropriate height off the metal. Sheet and plate thickness can vary and can be warped.
