3 Nozzle
Replace the nozzle if the passage hole for the plasma arc has
stretched or deformed.
If the nozzle surfaces are highly oxidised, clean them with very
fi ne sandpaper.
4 Air distribution ring
Check that the air passages are not obstructed.
Clean the ring well and replace it if damaged (burnt, deformed,
