It is recommended to check / adjust the pressure in case:
- of change of connection point or of pneumatic installation
- of change the torch length
- of change the type of consumables
- of doubt
Press the button , the air comes out continuously from the torch, the LEDs of the Bar-graph illuminate and indicate the pressure read at the
entry of the torch.
Unlock the pressure adjustment knob by pulling it towards you then turn it to adjust the proper pressure to the work to be done. Once the pressure
is set correctly, lock the wheel by pressing it.
The pressure depends on:
- torch length (a longer torch requires a higher pressure to compensate for the loss of load due to the length)
- type of work i.e. cutting or gouging (gouging consumables require lower pressure).
- consult the torch instructions or markings on the machine in order to set optimal air pressure.
Recommended pressure:
CUTTING CURRENT SETTINGS
In order to achieve the expected performance and maximise the lifte cycle of the consumable life, ensure that the power set matches
the consumables.
- Cutting nozzle 20-50 A : respect the current between 20 et 50 A.
The adjustment is made simply by using the current potentiometer (FIG 2 - 8).
CUTTING MODE CHOICE
Choose the cutting mode by using the selection button
Cutting of solid sheets
This is the most commonly used mode. Pull the trigger to create the arc, and release it to stop or ""unblock"" (the arc stops by
itself). To restart the work, release the trigger and pull it again.
Cutting of perforated sheets
This mode follows the same principles as the previous one except when ""unblocking"": the arc will start again if the trigger
while the trigger is pulled. This mode is more comfortable to use, as it avoids constant pull and release of the trigger.
Cutting long pieces of metal
This mode allows the operator to release the trigger during the cut, which will continue until the trigger is pressed again or
""unblocking"". This mode prevents fatigue and keeps your hand a little further away from the cutting area.
CUTTING SEQUENCE
1- When the trigger is pressed, the pilot-arc starts. It is a low power arc generated between the electrode and the nozzle and it allows the arc to
start on the piece of metal to be cut.
2- When the pilot-arc touches the plate, the plasma cutter detects the start. The arc then flows between the electrode and the plate, and the
machine increases the current up to the value set by the operator.
3- At the end of cutting (trigger release or unblocking), the arc stops, the air continues to come out for several dozens of seconds to cool the torch
and consumables down.
