Fig. C
- Connect the relative earth clamp to the workpiece or to
the workpiece support in an area free of rust, paint,
grease, etc..
- Connect the TIG torch power cable to the snap-on
connector marked - (negative).
2) Adjust the welding current using the potentiometer (Pos. 3,
Fig. A).
3) Adjust the process switch (Pos. 6, Fig. A) to TIG (switch
lever moved to the left-hand side).
4) Start the welding machine by selecting pos. 1 on the line
switch (Pos. 7, Fig. A).
5) The white LED (Pos. 1, Fig. A) indicates that the welding
machine is powered and ready to work.
6) Adjust the gas flow by manually turning the valve on the
TIG torch.
7) The "Lift" function strikes the arc when the TIG torch
electrode comes into contact with the workpiece and is
then removed (see Fig. D).
8) Carry out TIG welding.

PART TO BE WELDED
The part to be welded must always be connected to earth in
order to reduce electromagnetic emission. Much attention
must be afforded so that the earth connection of the part to be
welded does not increase the risk of accident to the user or the
risk of damage to other electric equipment.
When it is necessary to connect the part to be welded to earth,
you should make a direct connection between the part and the
earth shaft. In those countries in which such a connection is
not allowed, connect the part to be welded to earth using sui-
table capacitors, in compliance with the national regulations.

Maintenance

ATTENTION: before carrying out any inspection of the inside
of the generator, disconnect the system from the supply.
SPARE PARTS
Original spare parts have been specially designed for our equi-
pment. The use of non-original spare parts may cause varia-
tions in performance or reduce the foreseen level of safety.
We decline all responsibility for the use of non-original spare
parts.
GENERATOR
As these systems are completely static, proceed as follow:
• Periodic removal of accumulated dirt and dust from the
inside of the generator, using compressed air. Do not aim the
air jet directly onto the electrical components, in order to
avoid damaging them.
• Make periodical inspections in order to individuate worn
cables or loose connections that are the cause of overhea-
ting.
