3.2 DESCRIPTION OF THE EQUIPMENT.

C – Procedure and mode selector switch
This push-button selects the welding procedure (MMA or
TIG) and mode (2-step, 4-step and 4-step with dual
current level).
The selection changes each time the button is pressed.
The LEDs light next to the various symbols to display
your choice.
A LED – MMA (Manual Metal Arc)
welding.
This machine can melt all types of coated electrodes,
except for cellulose.
In this position, only the R knob is enabled to adjust the
welding current.
(manual)
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time (L LED
on), until it reaches the value set by means of the R knob.
When the trigger is released, the current begins to drop
over the previously set "slope down" time (A5 LED on),
until it goes back to zero.
(automatic)
This program differs from the previous one in that the arc
is both started and extinguished by pressing and
releasing the TIG torch trigger.
with dual current level (automatic dual level)
Set the two current levels before starting the arc.
First level: press the G key until the M LED lights, and
adjust the main current using the R knob.
Second level: press the G key until the A6 LED lights,
and adjust the current using the R knob.
After arc ignition, the current begins to increase over the
previously set "slope up" time (L LED on), until it reaches
the value set by means of the R knob. The M LED lights
and the display T shows the current.
Should it be necessary to reduce the current during
welding, without extinguishing the arc (for example when
changing the weld material or the working position,
moving from horizontal to standing position, etc.) press
and immediately release the torch trigger, the current will
switch to the second value selected, the A6 LED will light
and the M LED will go off.
To return to the previous main current, press and release
the torch trigger once again, the M LED will light and the
A6 LED will go off. To stop welding at any time, simply
hold down the torch trigger for more than 0.7 seconds,
then release. The current begins to fall to zero within the
previously set "slope down" time interval (A5 LED on).
If you press and immediately release the torch trigger
during the "slope down" phase, you will revert to "slope
up" if this is set to any value greater than zero, or to the
lesser current value of those set.
N.B. the wording
RELEASE" refers to a maximum time of 0.5 seconds.
