Installing / Removing the Torch Head
WARNING: Remove primary power from the Spirit system!
1. Each time the torch head is connected to the torch base, use a cotton swab to apply
a small amount of o-ring lubricant on each of the seven o-rings on the top of the
torch head. Reminder: do not use an excessive amount of o-ring lubricant.
2. Align the indicator on the torch head (circle) with the one on the torch base (slot).
3. Apply enough upward force to engage the threads while tightening the attachment
ring. Turn the attachment ring to the RIGHT to tighten.
4. Keep tightening the attachment ring until it stops. There should be no gap between
the attachment ring and the o-ring on the torch base.
During this process, a small amount of coolant will collect in the torch head.
It is normal for this coolant to discharge between the o-ring on the torch base and
the attachment ring while the system is being pressurized. If coolant continues to
discharge after the system is pressurized, turn off the plasma power supply, remove
the torch head and inspect the o-rings for damage.
YES NO!
To remove the torch head, turn the attachment ring to the LEFT.
