H. How To Refill The Cooling Fluid
Only use original MIG/TIG coolant for refill. It
provides protection against frost down to 4°F
(-20°C). If using other coolants, the coolant pump
could be damaged. Coolant circulation has to be
checked at regular intervals. Reliable coolant return
flow is essential to ensure the coolant is not lost and
the coolant cooled MIG torch is not damaged. Check
the level of the coolant every day before operating.
The coolant must be visible when the tank cap is
removed.
CAUTION
Remove the pin from the breather hole in
the cap of the coolant tank as leaving the
pin in the cap may cause a coolant flow
error.
