Has anyone ever made/installed “shorter” table “slats” so that the work sits lower in the table, allowing the fluid to make contact with the bottom of the piece ?
I’m using GreeCut plasma fluid. They recommend to have the fluid in “direct contact (no air gap) with the metal being cut to improve plasma torch cutting finish”
My idea was to make shorter slats to achieve this.
I do not recommend this.
You do not have to do this…within 1/2" is plenty close…I cut 22 gauge it hardly warps at all…
by lowering the slats you have a higher risk of warping or puncturing the water pan…
I also have a small spray bottle that has a hand pump to put pressure in it…
I keep the sprayer on hand for some tricky cuts to keep the metal cool
Not much help, but I saw a system that floods water from table onto the top surface of work piece for cooling. This might be worth googling? (plasma torch flood coolant, or something like that)
there was one person here who added a water pump and nozzle to flood the piece of metal to keep it cool.
But remember the main reason metal warps is it the cut speed and amps are not tuned in properly to maximize the torch and table speed.
if you want to drop the slats then I would recommend you place a piece steel in the bottom of the tray raised a little bit off the bottom to act as a heat sink to protect the bottom.
I can’t see why that wouldn’t work, you could make sawtooth version while you’re at it.
Just don’t do a high amperage operation.
And it might make a bit of a mess with the water.
I am curious if it will affect the cut quality.
More chance of burning through your pan on the pro.
I feel as if taking a quarter inch of the table slats wouldnt risk burning through. but definately something to take into consideration.Thanks for the replies everyone.
