GYS CUTTER 70 CT Mode D'emploi page 18

CHOICE OF CONSUMABLES
Refer to the charts on the side of the machine to choose the appropriate consumable.
For cutting:
Two caliber of consumables are available:
- small work with the nozzle 20-50 A marked «45 A»
- intensive work with the 70 A nozzle marked «70 A»»
For gouging:
One caliber is available : 70A
Gouging is used to remove metal in order to :
- perform chamfers
- perform bleeds
- remove weld beads
AIR PRESSURE ADJUSTMENT
In order to improve cutting performance, make sure air pressure is set to an appropriate level.
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
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 (ref. 037571) : respect the current between 20 et 50 A.
- Cutting nozzle 70 A (ref. 037568) : set the potentiometer to the maximum.
- Gouging nozzle 70 A (ref. 037595) : set the potentiometer to the maximum.
The adjustment is made simply by using the current potentiometer (FIG 2 - 8).
