CAUTION
!
22. Check coolant level and add if necessary.
Commercial Antifreeze/Coolant Will Cause
Torch To Malfunction
Use Special Torch Coolant! P/N 156N05
Due to high electrical conductivity, DO NOT
use tap water or commercial antifreeze for
torch cooling. A specially formulated torch
coolant is REQUIRED. This coolant also
protects for freezing to -34° C.
Operating unit without coolant will cause
permanent damage to the coolant pump.
