1 If a circuit breaker is used in place of a fuse, choose a circuit breaker with time-current curves comparable to the recommended fuse.
2 "Time-Delay" fuses are UL class "RK5". See UL 248.
3 "Normal Operating" (general purpose - no intentional delay) fuses are UL class "K5" (up to and including 60 amps), and UL class "H" ( 65 amps and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.

Remove shielding gas cylinder
from rear of unit to fill coolant
tank.
Unscrew cap from tank.
Use table to select proper coolant,
and fill tank until coolant appears in
upper half of indicator.
Check coolant level after attaching
torch coolant hoses and running
cooler. Be sure coolant appears in
upper half of indicator. Add coolant
if necessary.
