With reference to Fig. 8 and 8/A for torch CP 162C and Fig. 9 for torch CP 70C, parts subject to wear are as follows:
electrode A, swirl ring B, nozzle C and nozzle guard E. These should be replaced after unscrewing nozzle holder D.
Sometimes, for torch CP 162C, it may be necessary to clean the inside of swirl ring B. If necessary, use the appropriate
tool as indicated in figure 8/A. Electrode A must be replaced when it shows a crater approx 1.2 mm at the centre.
CAUTION: when unscrewing the electrode do not force it but apply force gradually until the thread is released. The new
electrode must be screwed into its seat and locked without fully tightening.
Nozzle C must be replaced when its central hole is damaged or becomes larger than the hole on a new part. Delaying
replacement of electrode and nozzle causes part overheating, which can reduce the lifetime of swirl ring B.
After replacement, check that nozzle holder D is sufficiently tightened.
CAUTION: screw nozzle holder D onto the welding torch body only when electrode A, swirl ring B, nozzle C and nozzle
guard E are fitted.
If these parts are not present, device operation and the operator's safety are at risk.

HELPFUL HINTS

- Should the equipment air contain plenty of moisture and oil the use of a filter dryer is recommended. This will pre-
vent excessive oxidation and wearing of consumables, welding torch damage and reduction in cutting rapidity and
quality.
- Air impurities cause oxidation of the electrode and nozzle and may make pilot arc start-up more difficult. If this con-
dition is present, clean the electrode terminal end and the nozzle interior with thin abrasive paper.
- Make sure that the new electrode and nozzle that are going to be assembled are perfectly clean and oil-free.
- To avoid welding torch damage always use Cebora original parts.
