SECTION 3
G. Remove coolant fill cap at front of console and fill
coolant tank with 4 gallons (15 l) of plasma coolant.
See Figure 3-11. Reinstall cap.
Due to the high electrical conductivity, use of tap water or
commercial antifreeze must NOT be used for torch cool-
ing. A specially formulated torch coolant, P/N 156F05 (1
gallon (3.8 l) container) is available and recommended for
torch cooling. The coolant also provides freeze protection
down to -34° C.
Operating the unit without coolant will cause permanent
damage to coolant pump.

H. Make all connections to the CNC and height control.
See instructions provided with equipment supplied.
I. Connect gas supply to flow control. See gas require-
ments as listed in Tables 2-3, 2-4, and 2-5. (See

1. Close all valves on the gas flow control cabinet.
2. Set all inlet gas pressures to 125 psig (8.6 bar).
3. Turn the power source ON. The amber light to the
left of the switch will glow, the console fan will
operate and coolant will flow.
4. Coolant pump pressure should be 80 to 90 psi (5.5
to 6.2 bar). See coolant pump pressure gauge on
front of console.
5. Check for leaks on connections No. 6 and 7 on the
back of the console and in the junction box.
Check the torch power cable and pilot arc cable
connections in the junction box.
6. Check the vent hole in the side of the torch sleeve
and the torch consumables.
7. With console ON, use a solution of soap and
water. Check all gas connections for pressure
tightness as per following:
