Best water table fluid and/or additives to keep water from freezing?

Hi. Minnesota CF Pro rookie just setting up my table in a (soon to be) cold, below freezing Minnesota garage. I’ve searched the forums for 1,000 ideas and am more confused now then when I started. If someone with actual anti-freezing water table experience could simply tell me what to buy…I would GREATLY appreciate it!

Heat shop do not put antifreeze in water table. Toxic. Or could put a 1500-watt block heater in water horse trough heater would work to.


@jpaavola This thread goes through the anti freeze topic indepth.

I let it freeze just like me in the shop.

as it has been stated over and over…it is not the table fluid I would be worried about…it is the electronics and motors that can get condensation from hot/cold changes…

and do not add anything other than what a plasma cutting fluid supplier has made…


I will have it heated but not 24/7. Only used weekends. I am looking at a few options for farm feeder tanks. I just need to keep disk away from the cut area.

Your favorite water table fluid?

Tru dat! Ice expands tho. Might be a lil hard on the tanks. Especially the seam in the middle but I will likely weld the two tanks together to skip the forewarned leaky seam issue.

I just drain and dump my water after every use in the winter. 15 gallons

It’ll be fine, think old school metal ice cube tray. It will expand up since there is no resistance.


You remove heater when cutting, just use when not using table. I use plasma green in water.
