MAINTENANCE
4.1 NOZZLE
Do not remove the nozzle immediately after cutting, but let it cool
during the after-gas flow.
Do not use tools such as slip-joint pliers, in order to avoid distort-
ing the nose of the torch.
The nozzle is easily unscrewed using the combination wrench
W000302578.
Replace the nozzle when the edges of the cut are no longer even,
or when the cutting speed is significantly reduced.
4.2 ELECTRODE
50 A
If the electrode is drilled, make sure that thenozzle's gasket is re-
paired, in order to guarantee:
4,80
1. the compressed air flows,
3,30
2. the service life of the wear parts,
2,20
3. the cutting performance of the torch
1,50
Do not try to use any more of the electrode, which would entail a
0,90
risk of piercing the dip tube and destroying the torch.
0,50
WHEN REPLACING THE ELECTRODE AND THE NOZZLE,
USE ONLY THE WRENCH W000302504 SUPPLIED WITH THE
TORCH.

Check the depth of wear of the electrode: 1.5 to
2 mm.
This degree of wear corresponds to an average
period of use of 1 to 2 hours, as a function of the
power of the arc and the number of ignitions.
