3.13 Install Consumables

Note: When installing the consumables, do not use an excessive amount of
o-ring lubricant. 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 power to the Power Supply. For multi-torch setups, ensure
this is the Power Supply physically connected to the serviced torch.
If applicable, remove the Quick-Disconnect Torch Head and place on a clean
work surface.
Apply lubricant BK716012 (or BK716012-2) 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
(BK602396) and ¼" driver (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. The larger nozzle o-ring will fit completely inside the torch.
Apply lubricant to all o-rings on the torch. Thread the retaining cap onto the
torch until it is fully seated.
Apply lubricant to the o-ring on the shield cap. Push the shield cap onto the
retaining cap until it is fully seated.
Thread the outer retaining cap onto the torch until it is fully seated.
If applicable, install the Quick-Disconnect Torch Head.
