CUTTING SPEED SCHEME
have the thread unlocked. Lubricate the thread of the new
electrode with silicone lubricant (on supply with the unit).
This new electrode is required to be screwed in its housing
and locked without tightening.
Nozzle C should be replaced when its central hole is
damaged or enlarged with respect to the new part (see picture
13).
Use of worn electrode quickly wears out the nozzle.
Excessive use of electrode causes overheating and reduces
the life of diffuser B.
Make sure that after replacing it, nozzle D is tight enough.
ATTENTION! Nozzle holder D should be only screwed on
head when electrode A diffuser B and nozzle C are
assembled.
2) Replace torch body E (see picture 11).
Withdraw handle F from body E by swaying it and making sure
that button wires are not torn when separating both parts.
Withdraw the G and H safety contacts wires.
Withdraw the contact L. Unscrew fitting I after cutting the
insulating hose K.
Assemble the new body of torch making all above operations
inversely.
Fitting I is insulated by shrink hose K stuck to the fitting when
heated by a small source (ex. a lighter).
Before replacing handle make sure that cables are far away
from each other and that fittings are tightly secured.
3) Substitution of adapter (W) (see picture 11)
Remove ring nut (Z) and cut the clamps locking cable (R).
Loosen screw (Y) and extract cover (X). Extract the control
cable pins (N) and (O) and the red cable pins for pilot arc
(P). Cut the insulating sheath (K2) and loosen the adapter
body (U) from connector (Q). Fit the new adapter body
carrying out all previous operations in reverse order. Use
sealing adhesive for threads in order to lock the adapter
body thread (U) on connector (Q). Pins (N) and (O) of the
control cable should be connected to contacts (1) and (9)
of adapter body (U). Pins (P) of the red cable for pilot arc
should be connected to contacts (5) and (6) of adapter
body (U). Sheath (K2) acts as insulating material and
adheres to connector (Q) after warming it up.
4) Replacement of cable R (see picture 11)
To replace cable follow instructions as per pos.2 and 3 and
connect S.
N.B.: Fitting S should be properly insulated.
5) Replacement of handle with button.
To replace handle with button it is required to follow instructions
as per pos. 2.
MAINTENANCE AND CONTROL
It is recommended to keep nozzle free from slag.
Avoid using sharpened bodies thus avoiding damaging the
nozzle hole.
Even if the unit is provided with an automatic device for water
discharge, working whenever air feed is closed, it is recommen-
ded to check from time to time that no water remains in trap
I of reducer (picture 1).
It is required to clean from time to time the unit inside and make
it free from metal dust by means of compressed air.
Operations to be carried out inside the unit must be effected
after disconnecting feed cable.
not started, check the following:
• air pressure is enough.
