MicroArc coolant pooling?

[Dr_Harold_Jones]

Just wondering about opinions on what to do and whether it’s safe (for the MicroArc) to let coolant pool

. It’s a bit of a pain to clean out and even after blowing the coolant out (which I am unsure is good because it removes the coolant or bad because the air blows coolant against and invariably into the seals) there will be more coolant there in the morning. So what is the recommendation to maximize MicroArc life. Do I even need to worry about the is?

The MicroArc will not be harmed if coolant gets into the chuck cavity or the thru bore. A standard air gun is also not strong enough to force the coolant into the electrical box through the seals, so either cleaning the coolant out or leaving it be will not affect the unit’s lifespan one way or the other.
