4. RESET - BUTTON (Ref. 4 - Picture 1 Page 3.) This button
puts the power source back into service after completing the
torch servicing operation. When the shield cup is screwed on
the torch head, the L.E.D. (Ref. 5 - Picture 1 Page 3.) is off.
It's necessary to switch the button (Ref. 4 - Picture 1 Page 3.)
if you want to cut again.

6. SWITCH REGULATION OF THE CUTTING CURRENT:
(Ref. 6 - Picture 1 Page 3.) In different positions the power
source supplies the specified cutting current.

3.0 INSTALLATION
IMPORTANT: BEFORE CONNECTING, PREPARING OR US-
ING EQUIPMENT, READ SAFETY REGULATIONS.
3.1 ELECTRIC CONNECTION.
This power source is supplied factory set for operation at 400V.
Before hooking it up to the power supply check that the mains volt-
age is compatible with the preset voltage, otherwise it is essential
to change the power source setting in accordance with the avail-
able supply voltage by means of the internal terminal board, which
is shown in the following diagram:
Make sure the mains socket outlet is equipped with a fuse rated
as shown in the following table:
Power supply
220V - 50Hz - 3ph
230V - 50Hz - 3ph
380V - 50Hz - 3ph
400V - 50Hz - 3ph
Make sure equipment air ventilation gates are not obstructed at all times.
3.2 AIR PRESSURE CONNECTION.
Connect the power source to the factory compressed air line by
means of the pressure reducer on the rear of the unit.
