5.6 Replacing Consumables
DANGER
Electric Shock Can Kill.
Remove primary power from the System before installing or
removing consumables.
WARNING
Hot Parts Can Burn Skin.
Do not touch hot parts with bare hands.
Always use gloves when handling the torch as it can be hot after
cutting, especially with high amperages and long cut times.
Allow cooling period before working on the torch.
Note: When installing the consumables, do not use an excessive amount of
o-ring lubricant. Also ensure that the lubricant is only placed on the o-rings.
Excess lubricant can interfere with gas flow, which can cause starting
problems, poor cut quality, and short consumable life.
Remove primary (wall) power from the System.
Unscrew the outer cap from the torch.
Pull the shield cap off of the retaining cap or remove it from the outer cap.
Unscrew the retaining cap from the torch.
Pull the nozzle straight out of the torch. The swirl ring will come out with the
nozzle. Do not use tools.
Separate the swirl ring and nozzle by pulling them apart. Do not use tools.
Unscrew the electrode from the torch using a 10mm, 6-point deep socket (part
number BK602396) and ¼” driver (part number BK277086).
Inspect the cooling tube in the torch for damage. If damaged, replace by
unscrewing the cooling tube using an adjustable wrench across the flats.
Inspect all consumables and o-rings for damage and excess wear. Refer to
Section 6.3. Replace with new consumables as necessary.
Apply lubricant BK716012 to the o-ring on the electrode. Push the electrode
over the cooling tube and thread the electrode into the torch by hand. Tighten
the electrode using a 10mm, 6-point deep socket (part number BK602396)
and ¼” driver (part number BK277086).
Apply lubricant to the o-rings on the swirl ring. Press the larger end of the
swirl ring into the bottom of the nozzle until it is fully seated.
Apply lubricant to the o-rings on the nozzle. Push the nozzle/swirl ring onto
the electrode until it is fully seated. The larger nozzle o-ring will fit completely
inside the torch.
