Hi,I have just got my plasma machine running,I am looking for some
help on cutting ramp speeds
Should i keep the ramp speed to the minimum the motors can handle so
the require cut speed is acheived quicker.
Thanks in advance

I don't think any changes in acceleration or deceleration are needed
for torch cutting. Just set your machine for the best performance.
Slower ramps means the machine will run smoother (less jerkyness)
which is good for torch work. A plasma is not exactly a precision
cutting machine and the flame trails behind the tip to an extent. The
biggest challenge is to get consistant piercing and constant torch
height above the material (unless you are using a drag tip).

The most important thing is to have the conturing feature enabled
to make the curves and shapes you cut nice and smooth. I use between
70 and 80 IPM on 11Ga steel. I cut some 1/4" stock the other day and
I got good results at 40IPM. This is with a 55A torch and the Torch
Height Control running.

Hi Tom,Thank you,I will play around with the settings
,I plan to lift the torch between cuts but have the
head floating,this will do for now as i learn more and
the THC kit becomes available,when you say contouring
is this constant contouring,if i want sharp pointsand
corners should i turn constant contouring off.
