Greetings all;
I have just found that food grade antifreeze in the water seems to be a
nono for long term useage as motor coolant.
Why do you need food grade in a recirculating system? How
about plain old antifreeze, which has lubes and
anti-corrosion additives. Or, they make a coolant for TIG
torches that has the same stuff.
I've had the same stuff in my TIG torch for over a decade,
and it still runs fine.
