Making my first cuts today and I have a quick question...
After the cut is complete and the torch goes back to 0,0 it leaves the air on for like 10 seconds and then shuts off.
Is this something that is done to clear all water out of the consumables or is there some setting that i can modify to make this a little shorter.
The splashing isn't so bad while cutting, but this last 10 seconds makes a hell of a mess on the sheet.

This is to cool the torch head.

You might try putting a small sheet of metal at the 0,0 position to stop the splashing, or move the torch somewhere else after it goes to 0,0.

Re: End of Cut - Compressed Air Off Delay
The air flow after the cut is called "Post Flow", and is absolutely necessary for consumable parts life. The end of the electrode inside a plasma torch reaches 3100 degrees F while cutting, the post flow cools this between cut cycles. If you could reduce the post flow...you could save air, but use more consumables! Jim Colt Hypertherm

I ended up cutting strips of plexi that stand about 8in tall, and putting them on the edges of my water table to avoid the splashing

Re: End of Cut - Compressed Air Off Delay
Thanks guys!
I started playing PacMan with the torch head using the arrow keys during this post flow period and use the air to blow the water off of the sheet from cutting.
So far I am pretty happy with the water table. I decided to make it a habit to wipe all of my linear rails down with air tool oil at the end of the day. Not sure if it is the right thing to use, but an old millwright told me that it would help keep the rails from rusting and will help keep the linear bearing trucks lubed up.
