The left U/D command:
· in synergic programs, adjusts the welding parameters
along the synergic curve.
· in conventional MIG, adjusts the wire speed.
· within saved programs, selects them numerically.
If you intend to save with the U/D torch inserted (LED AT
lit), you may choose the program number via the U/D but-
ton.
The right U/D command:
· in synergic programs, adjusts the arc length.
· in conventional MIG, adjusts the voltage
· not active within saved programs
When the U/D torch connector is inserted, the LED AS
lights to indicate that the torch has been recognized.

7 MAINTENANCE
Any maintenance operation must be carried out by qua-
lified personnel in compliance with standard CEI 26-29
(IEC 60974-4).

7.1 GENERATOR MAINTENANCE

In the case of maintenance inside the machine, make
sure that the switch BU is in position "O" and that the
power cord is disconnected from the mains.
It is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
7.2 PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
