Heigth Control

[rocksolidframes]

I have a tracker table with a thermo dynamics 101. I'm cutting 12 guage steel and would like to maintain a .060 or 1/16 inch torch heigth. Standoff is set at .3, after piercing the torch self adjusts to about .180. When using AVC I adjust it down while cutting but as soon as I start the next part it resets itself back to .180. How can I make it stay at 1/16 clearence? I don't have anything on my machine control that says anything about torch heigth. I appriciate any help I can get.
Thankyou, Saddlebur

Mr. Leatherhands,
Thanks for the reply, I just tried it again with the AVC on and bumped it down with the - key and it stopped and a window opened saying something about a torch failure and I didn't take it down to far it still had clearence so I unchecked AVC and I finished the piece by bumping the - key after it pierced each time for about 20 times. If you look at my other post on the general forum, subject is no fire first one inch of travel, we corrected that problem, but maby you can see where i've been with settings and maby I have created an underlying problem.
thankyou for your help, Saddlebur

Mr. Leatherhands,
I don,t know the age of my machine, it looked like new when I bought it, maby the serial number (080906) will help. I will try again to adjust the torch down using the AVC/THC dial. But it doesn't act right when it pierces, it plunges down as normal then it raises up to a lower heigth then it is programmed for, it pierces, then it raises up higher as it starts the cut. It like the pierce heigth and cut heigth are reversed. Thanks for all your help.

I tried cutting with the AVC on, the torch raised up .163, standoff is .3, it pierced the steel and shut down. The Torch Fault window came up, it said Flame Out Detected- Command and Cut has paused the system. If anyone has some input it will be greatly apprieciated.

Thanks, Saddlebur

Mr. Leatherhands,

I eliminated the flame out error. Thank You. I cut a 4" square as you suggested. I adjusted the torch down while cutting with AVC adjusting knob. I got a 1/16th of an inch clearance between torch and steel.

Problems. The torched plunged down and touched the plate and raised up only two cut height and started cutting. It did not raise up to pierce height. Then after completing cut it remained at cut height and did not raise up out of the way as usual.

Thankyou, Saddlebur
