4. Unscrew the nozzle retainer/diffuser. Inspect for
damage, especially where the retainer contacts the
nozzle. The surface between the retainer and the
nozzle creates a metal to metal seal for the
coolant. Any damage to this sealing surface will
cause a leak resulting in poor cutting. Replace as
necessary, but do not attempt to repair. Check
small gas passages for blockages. Clear
blockages with an air stream.
5. Use the tool provided to remove the nozzle. Place
the slot around the nozzle groove and pull it free.
6. Remove the swirl baffle from the nozzle. If the
baffle remains in the torch, it will come free when
removing the electrode. Check the small gas
passages of the swirl baffle for blockage and clear
blockages with an air stream. If blockages cannot
be cleared, replace baffle. Do NOT
in these holes when trying to clear them. Distorting
these holes will impair cutting performance.
