Replacing the Torch Coolant
The torch coolant should be flushed out of the system every six months
and replaced with new coolant. The following procedure should be used
to prevent damage to the cooling system.
Note: When handling coolant, it is recommended that you wear
nitrile gloves and safety glasses.
1. Remove primary power to the system.
2. Remove the rear cover of the power supply to expose the cooling
system.
3. Remove the coolant reservoir cap/level gauge.
4. Make sure that consumables are properly installed in the torch head
and that the torch head is installed onto the torch base.
5.
Using a funnel to collect the coolant,
unscrew the drain petcock on
the bottom of the coolant reservoir. Leave the funnel in place after
the coolant drains out of the reservoir.
6. Remove the torch coolant supply hose from the rear of the power
supply. Note that the coolant supply hose has right hand threads.
7. Blow compressed air (100 psi maximum) into the coolant supply
hose. This will clear the coolant out of the torch, torch leads, and
heat exchanger. Note that the coolant will be forced into the reservoir
and will drain out of the drain petcock.
8. Unscrew the lower portion of the coolant filter housing and remove
the coolant filter/deionization cartridge. Replace with new filter.
9. Reconnect the coolant supply hose.
10 Refer to Section 3 for the remaining steps required for Filling the
Torch Coolant Reservoir.
Only use Kaliburn approved torch
coolant solution
. Commercially available antifreeze contains
corrosion inhibitors that will damage the cooling system. See Section
3 for more information on torch coolant requirements.
