Menu Basic Setup; Welding With Coated Electrodes (Mma) - Helvi COMPACT 306C Manual De Uso

MENU BASIC SETUP

Press the button T4 during the generator 's
ignition (while the displays is viewing the sof-
tware version [Uxx]) to enter the menù whe-
re the general functioning and the regulation
mode of the unit can be set and where the
generator can be reset as default.
The display will view "P x", with the knob 2
select the desired P number. By pressing the
T4 button it will be possible to adjust the va-
lue of the P selected before. If value stays
unchanged for more than 5" the display will
get back to the main menu "P x".
With button T2 save the configuration, switch
off and ignite again the generator.
P 1: GENERATOR SETTING MODE
PFr: Professional mode of the welding scre-
en. The operator can adjust all parameters of
the welding cycle.
EsY: Easy mode of the welding screen. The
operator can adjust only some parameters,
the other ones are set automatically by the
generator.
P 3: WORKING MODE OF THE
REMOTE CONTROL
When the remote function is active, the LED
L1 lights.
An: The arcing occurs by pressing the pedal.
The welding current is adjusted through the
analog input of the torch trigger connector [0-
>10V = 5->Iweld]
dI: the welding current is adjusted through
two buttons connected to the torch trigger
connector.
LSt: by pressing the buttons it is possible to
scroll and charge the first 20 saved operator
points (see SAVE AND RECALL THE SET
WELDING PARAMETERS)

WELDING WITH COATED
ELECTRODES (MMA)
• Connect the ground lead to the negative
(-) socket of the generator (pos. 4) and the
ground clamp to the piece which is to be wel-
ded.
• Connect the welding cable to the positive
(+) socket of the generator (pos. 5) and cor-
rectly fix the coated electrode (filler material)
on the electrode holder.
Warning: Respect the positive or nega-
tive polarity (DC+, DC-) marked on the
packaging of the electrodes.
• While holding the electrode holder, sup-
ply the generator with power by pressing the
start/stop (ON/OFF) button on the rear panel
(pos. A) of the generator. Warning: The wel-
ding machine will suggest the configurations
used in the previous welding
• Use the buttonT2 to select the electrode
welding procedure (MMA).
• Use the button T4 to select "set" and set
the Hot Start and Arc Force parameters:
• Hs LED L15 on with fixed light – the di-
splay shows "H": rotate the adjustment
knob 2 to adjust the Hot Start value. The
display will show the set value.
• Af LED L16 on with fixed light – The di-
splay shows "A": rotate the adjustment
knob 2 to adjust the Arc Force value. The
display will show the set value.
• Use button T4 to activate or exclude the
VRD function.
IMPORTANT: For further information on
parameter functions and regulation in
MMA welding, please read the paragraph
on "CONTROL PANEL - BUTTONS &
LEDS".
• Wait 5 seconds. The generator will exit the
automatic parameter regulation menu.
• Adjust the welding current using the knob 2
(LED L2 on) or with the remote control knob
if the remote control has been activated with
button T1 (LED L1 on).
• The set current value depends on the ap-
plication of the welding, the type of electrode,
its diameter and on the instructions provided
by the electrode manufacturer (and present on
the packaging of the electrodes themselves).
• The table below contains basic information
regarding the range of currents used for each
diameter of electrode.
