WARNING
A clean, dry primary gas (air or nitrogen) must be
supplied to the machine. A pressure setting above
7,5bar could damage the torch. Failure to observe
these precautions could result in excessive operating
temperatures or damage to the torch.

English 10 English
Cutting Process
The air plasma cutting process uses air or nitrogen as
primary cutting gas and as torch cooling gas.
The pilot arc is struck as follow: the torch button
energize an electrovalve (solenoid valve). This valve
lets the gas flow during the cutting and the post-flow
stages.
The design concept at the basis of these power sources
is to have available a current which remains constant at
the set value, independently from the length of the
plasma arc.
When preparing to operate, make sure you have all
materials needed to complete the job and have taken all
safety precautions. Install the machine as instructed in
this manual and remember to attach the work clamp to
the work piece.
With the machine switched OFF, prepare the torch
with the consumables adequate to the desired
process (CUT / GRID / GOUGE). Refer to the
Torches Instruction Manual to select the correct
combination of consumables.
Connect the Torch and the worck cable to the
machine.
Turn ON the Power Switch placed on the back of the
machine; the Power ON/OFF LED on the front panel
will turn ON. The unit is now ready to operate.
Check that the primary gas is available through the
Gas Purge function.
Select the desired Operating Mode process.
Set the desired current value with the Output Current
knob.
To start the selected process just press the torch button,
making sure you are not aiming the torch gas blow
towards people or foreign objects. During the process it
is possible to hold the torch away from the work piece for
an extended period of time.
Once the process is terminated releasing off the torch
button will cause the plasma arc to be turned off; the gas
flow will continue to allow the cooling down of the torch.
The Post Flow time is proportional to the selected cutting
current and it is divided into 4 time ranges:
Selected Cutting Current Post Flow Time
Less than 30A 15seconds
Between 30A and 40A 20seconds
Between 40A and 50A 25seconds
Greater than 50A 30seconds
