CONNECTABLE PLASMA CUTTER 40A
PRACTICAL RECOMMENDATIONS
If the system air contains much humidity and oil it is required to use a drying filter to avoid
excessive oxidation and wear of consumable parts, to avoid torch damage or to reduce speed and
quality of cutting.
Impurities of air favour oxidation of electrode and nozzle and make it difficult to start pilot arc. If
this occurs, clean the end part of electrode and inside the nozzle with fine abrasive paper. Make
sure that new electrode and nozzle to fit are clean and degreased.
To avoid damage of torch and to prevent dangerous situations always use genuine spares.
TORCH MAINTENANCE
The introduction for torch are just for your reference.
Please be subject to the actual products if anything different or updated Replace wear parts (11)
The parts subject to wear are electrode A, diffuser B and nozzle C. nozzle holder D.

Either part may be only replaced after loosening nozzle holder D. Electrode A
should be replaced when a 1.5mm deep crater is created in the middle (12).
ATTENTION! Do not make sudden stresses when unscrewing the electrode,
but gradually force so as to 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 (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. The absence of sach parts
jeopardizes the machine working and particulary the operator's safety.
