On the pbs station on the hometime show they demonstrated a computer operated plasma cutting table that had water bed where the material was being cut, it sure was a nice set up.

The one they was using was red and it had water in the bed where the material was laid to be cut. The water was, or at least looked like it was touching the material. You could see the water moving from the air that was coming out of the torch head. I believe they were using a miller plasma cutter and the torch handle looked like the hand held torch and not a machine torch. The torch head had ice wrote on it. The torch handle for manual cutting on a thermal dynamics plasma cutter looks like it also, but they show a different head for the machine torch for the thermal dynamics. The cam plasma table had an automatic positioning set up that raised the torch the right height off of the material being cut. I bet it cost a fortune, but they don't never tell the cost of one.

It sounds as though you're describing a Water-jet Cutter there Toy.

Water under a plasma cutter would cool the material you're cutting and probably cause things to mess up, but with a waterjet you need the tank underneath to slow the jet of water down once it has done the work.

The one we have here at work is similar.
It's an "Abrasive" water jet. Essentially it works the same as a sand-blasting gun. They use water at 55,000psi / 3800bar instead of air, and the sand/water combination exit though a nozzle that's 0.8mm in diameter. (other nozzle sizes are available, but that's how we run ours)
Our is a "beveljet" capable of cutting up to 45ｰchamfers and up to 150mm thick steel - made by Waterjet Sweden

It didn't look like it was spraying water through the torch head and you could see the ark. I believe they called it a cnc plasma table but I wondered about the water touching the metal that was being cut. Hope they air it again I will pay more attention if they do.

Hmm... I'm stumped... I look forward to an update :licking:

Thanks!!

I'm a newbie in more ways than one: I'll hopefully be buying my first tractor tomorrow!!

Another thought for Toys... If cutting titanium and some steels with an abrasive waterjet it can spark quite a lot.... could that be mistaken for an arc?

Some plasma tables have a water table under them to catch sparks. It dosent actualy touch the metal... Is that possibly what you saw or was the metal submerged?

That is what I saw, I looked at plazma cutter tables on the net and there was one called victory that was set up like that and the water wasn't over the material being cut but you could see it blowing the water as the cuts was being made. The one I saw on the net was a huge table not something for the homeowner, but the one on home time was much smaller. They was talking about a new machine that was coming out soon that had a 2ft by4ft table but they hadn't worked out the kinks so they could price it that much lower than the 4ft by 4ft table. As computer illiterate as I am though I'd probably do better making me a table and using a pantagraph stylus type deal to cut out a pattern and use my training wheels to gauge the distance off the work. Sometimes simple is easier and for a hobby maybe even better.
