3. Alternating welding current frequency. 20 Hz to 100 Hz. Use
low frequency to achieve wider beads, and in reconstruction
operations. Use high frequency to penetrate into narrower beads.
In turn, the alternating mode (AC) mode may be pulsed to provide
special features, such as facilitating drop-per-drop filling, caloric
control or improved surface finishing. This mode produces pure
square wave without any passing time and excellent cleanliness.

WELDING FUNCTIONS BY POINTS, REPETITIONS
AND ROBOTICS
Selecting the SPOT function on button E gives access to
the configuration of spot welding parameters defined by
the duration of each cycle (from 0.1sg to 99.9s), the peak
current (5 to 190A), the base current (5 to 190A) the pulse
width in relation to the peak (from 1% to 99%) and the
pulse frequency (from 0.2 to 500Hz).
In 4T repeat functions after passing the T1 and T2 times
in the initial cycle, a repetition of the T3 (down ramp) and
T4 (up and weld ramp) times is established each time the
trigger is pressed. In 2T repeat functions, it starts directly
in phase T3 / T4. To exit the repetition cycles, raise the
torch to suppress the arc.
For automation / robotics functions, keep in mind that
the trigger input can be operated from any system that
considers it a normally open switch. Use of relay or
optoisolator is recommended. For questions, contact your
dealer.
Functions with coated electrode
With the VRD (voltage reduction device) function, the
electrode welding vacuum voltage is reduced to improve
the safety that may be needed in special environments
or situations. The price to pay is a slight worsening of
the initial priming of the bow, so if it is not required it is
recommended not to have it activated.
To optimize welding quality you can play with others two
parameters that allow changing the character of the arc and the
heat input They are the frequency, nº17, of the pulse in cycles
per every second (Hz) and the percentage distribution between
the current peak and base,
Finally, two response parameters can be adjusted arc dynamics
in electrode coated mode. They are the strength of arc, arc
force, nº26 so that it will be increased for electrodes cellulosic
or aluminum type and will decrease for electrodes softer
response such as rutile. With the family of basic electrodes
it is recommended to start testing in fit intermediate. The
last parameter, start pulse, or Hot Start, No. 27 ARC START,
establishes a brief increment of power just by priming the
electrode and allows the electrode to start without getting stuck
before entering the normal regime foundry.

SERVICING AND MAINTENANCE INSTRUCTIONS
5.
5.1.- Cleaning, maintenance, lubrication, sharpening.
For cleaning, always disconnect the equipment and wait at
least 10 minutes for the sake of safety regarding the discharge
of the power capacitors. Clean the housing using a slightly wet
cloth. Depending on the pollution of the work environment or at
least each 1000 hours, clean the inside with dry pressurized air,
removing the upper housing and removing dust, metal pollutants
and fluff, paying special attention to the dissipators and the fan.
The equipment does not need special maintenance by the user,
whereby careful use within the environmental limits is the best
guarantee for long years of safe service. It is recommended to
send the equipment to the technical services after each 3000
work hours or every 3 years for verification and recalibration.
5.2.- Repair services with directions.

List of user-replaceable parts
Due to the complexity and potential hazard, qualified intervention
is required, except for minor repairs as inspection of connections
and replacement of the standard power supply plug and revision
of the welding cables, which thus are not considered user-
replaceable parts.
