Introduction
Thank you for buying our product.
In order to get the best performance out of the plant and ensure
the maximum lifespan of its parts, the use and maintenance in-
structions contained in this manual must be read and strictly
complied with, as well as the safety instructions contained in
the relevant folder. If repairs to the plant are required, we rec-
ommend that our clients contact our service centre workshops,
as they have the necessary equipment and personnel that are
specifically trained and constantly updated.
All our machines and equipment are constantly developed and
so changes may be made in terms of their construction and fea-
tures.

Description
ROCK is a welding machine with inverter technology that can
be used, for professional welding, with rutile and basic elec-
trodes. It is extremely easy to use, guarantees excellent weld-
ing results and can be used anywhere thanks to its compact
size and reduced weight (workshops, maintenance, construc-
tion sites, etc.). The main characteristics of the ROCK weld-
ing machine are:
• Reduced weight and size, easy-to-carry.
• The weld machine has a strong handle all in one with the
frame, used for transporting the machine manually only.
• The welding machine is also equipped with an adjustable and
removable shoulder strap that allows for easy and comfort-
able carrying on the shoulder.
• The welding machine is equipped with a 3m ground cable
and electrode holder.
• Digital display as standard that allows precise setting of the
8
welding current.
8
• Switch with two welding processes: electrode and TIG.
• Electrode Antisticking function.
8
• Automatic "Hot Start" function which helps to achieve fast
and reliable arc striking.
9
• Automatic "Arc Force" function to avoid electrode/piece stick-
9
ing during welding. It also promotes a reduction in the spat-
ter generated by the welding process.
9
• TIG welding with "Lift" striking.
9
• It has an IP 23 S protection class so that it can be used un-
der the heaviest working conditions.
9
• The generator also conforms to all European Union stan-
9
dards and directives in force.
