TORch cOOlaNT PRePaRaTION

1 . Remove the cap from the coolant filter tank . Fill coolant tank with 2 gallons (7 .5
liters) of plasma system coolant (P/N 156F05) - supplied with the package . The
coolant also provides antifreeze protection down to -34° .
Due to high electrical conductivity, use of tap water or commercial antifreeze is
NOT recommended for torch cooling . Use of tap water can result in algae growth
in the water cooler and torch . Automotive type antifreeze will adversely affect
starting and will form deposits in the torch that will cause damage .
2 . With installation completed, check all gas and coolant fittings for leaks using a
standard solution .
