Kerf width?

[JoeRob]

I am sure I am missing something here so please help me to understand. Running the torch at 4oA will have a narrower kerf than at 60A, correct? And 60A will be narrower than 80A, correct? Or are all the kerf widths the same, for the proper speed and material thickness?

In general more amps will result in a wider kerf, the hole size in the nozzle or tip is specific to the amperage, compare an 80 or 85 amp nozzle with a 40 or 45, comparing hole sizes.

If I draw a circle of 2". I cut it out of 1/4" steel. Will the final cut be the same diameter on 45A, 60A, 85A? Or will each be a few thousandths larger due to the kerf?

You can set each KERF diameter in the TMCAD to accommodate the different diameters.





So in the NAME change to the plasma and amperage.

TYPE stays PLASMA

Under Parameters the D1 is the KERF Diameter

Turret 1

Priority 2 (if you are using a PLATEMARKER)

As you can see my setup has all of the amperages I run here at the shop.

Did you determine the kerf width by direct measurement? What kerf width is default on VMD and are there multiple widths already installed or do i need to create a plasma set up for each amp setup

Each amperage will have a kerf diameter that is "close" in the cut charts. Being that the kerf is controlled by speed, once you establish your proper speed you would then mic your line and get the exact kerf width.

The VMD does have a kerf that you can enter but that will be based on parts generated in the PARTS LIBRARY.
