The machine must be used by as few people as
possible. The equipment must never be used by
untrained operators.
The sequence to carry out the equipment start-up
is described below:
⇒
Connect the torch to CN3. Check it is
connected properly.
⇒
Secure the safety cap of the torch.
⇒
Connect the earth cable to CN2 and place it in
the cutting piece. The electrical connection must
be perfect.
⇒ Pl
ace ON/OFF switch l1 in position 1. Light l1
comes on.
⇒ C
heck that the red and amber lights are not
on.
⇒ D
etermine suitable cutting power through l2.
⇒ H
ightly press the torch pushbutton. Air will start
to flow.
⇒ C
heck that the pressure gauge M mark 5.5-6
bar. There must be airflow.
⇒
Press the torch pushbutton. Formation of arc.
Light L5 comes on.
⇒
The pilot arc which has formed is timed at 2
sec. In the event that the cutting operation is not
started the arc will automatically go out.
⇒
Begin to cut. Do not touch the part with the
nozzle. Use a guide shoe or separator. Light l4
comes on.
3.3 CUTTING PROCESS. GENERAL
RECOMMENDATIONS.
Before proceeding to carry out the cut, the
correct cutting intensity must be determined
depending on the work to be carried out.
When the thicknesses are under 8 - 10 mm
we recommend working with switch l2 in
position 1 using a 1.1 mm diameter nozzle.
When inserting a new electrode in the cutting
torch proceed to brush it to eliminate possible
surface insulating layers.
GAR CUT (V. INDUSTRIAL). Instructions Manual.
When using nozzle and long electrodes, for
security reasons, shield cup Ref. 51957/G
should be incorporated.
"Polish the electrode"
Carry out this operation whenever there are
problems in igniting the arc.
Form the pilot arc outside the part. Before
forming the arc we recommend pressing the
pushbutton slightly in order to have a prior
airflow. The pilot arc goes out automatically
after two seconds if no cutting is done.
If, after quite a long cutting process, we see
that the cutting torch is heating up, we advise
letting the post-flow of air cool down the
torch.
Determine the correct cutting speed. The
penetration as well as the cutting flash
depend directly on the speed used in the
process. The correct speed is considered to
be that which causes a maximum inclination
of the arc projected of 7 to 15º with respect
to the perpendicular of the part.
Do not touch the cutting part with the nozzle.
Keep (especially in point 2) a minimum
distance of 5 mm. Use an cutting guide shoe.
When you are going to finish the cutting
operation (keeping the pushbutton pressed
down) separate the torch from the part, the
arc will automatically go out. With this action
we increase the life of the main contactor of
the equipment.
Do not activate the control switches during
the cutting process.
Any elements, accessory or instrument which
is added to the equipment must maintain the
basic safety conditions of the equipment. All
added equipment will comply with the
Standards and Regulations in force.
WARNING !
IF THE SAFETY CAP OF THE TORCH HAS
NOT BEEN INSERTED, THE MACHINE WILL
NOT BE OPERATIVE.
