of the workpiece can be selected turning
knob 8 (Fig.1). (Each time the knob is
turned, the selected thickness is
displayed on panel 1 for app. 2 seconds
then the welding current is displayed
again.)
The wire speed is set automatically in
accordance with the programme selected
using the appropriate mode selection
knob (Fig1 – 5). Basically, knob 8 sets
the welding power according to the
thickness
of
the
workpece.
Thicker workpieces require more power.
The automatically-selected wire speed
can be fine-tuned using the knob 7
(Fig1).
The quality of the weld can be improved
even further using the “electronic
inductance” knob (Fig1 -6 ).
3.2 MMA WELDING
(Fig1: Led 4 ‘OFF’)
Turn knob 5 (Fig.fig1) to the MMA
position.
(Line 1, Fig.5)
Electric MMA (Metal Manual Arc) and
SMAW (Shielded Metal Arc Welding) are
both manual procedures exploiting the
heat generated by an electric arc that is
produced when covered welding
electrodes make contact with the
workpiece. It is commonly used due to
its versatility. In fact, welding jobs can be
performed anywhere: in a workshop, in
the open, in confined spaces or hard to
reach areas. A wide range of electrodes
are available, suiting all requirements.
The arc is generated touching the
electrode
to
the
workpiece.
The potentiometer knob (Fig. 1 – 8)
regulates the welding current (thicker
workpieces require higher current
settings).
The display panel (Fig.1 – 1) shows the
current value selected.
While welding the following features
come into effect:
Arc Force:
A temporary increase in the initial
welding current to ensure the generation
of an arc quickly and reliably.
Antisticking:
Stops the welding current
if the operator makes a mistake causing
the electrode to stick to the workpiece.
The electrode can be removed from its
clamp without causing damaging sparks.
The correct electrode and earth clamp
connections are shown in Line 1 of
Figure 5. The electrode clamp is
connected to the positive pole and the
earth clamp is connected to the negative
pole. Check these connections with the
instructions on the electrode packaging,
inverting them if necessary.
4. CONNECTION TO POWER SUPPLY
Before plugging the unit in, check the
power supply voltage, phase and voltage
frequency.
The permissible voltage is shown in the
“Technical Specification” chapter of this
manual and on the unit nameplate.
Ensure the welder is earthed
appropriately. Also check that the plug
provided with the unit is compatible with
the local power grid socket. Make sure
that the power supply is sufficient to
operate
the
welder.
The types of power supply protection
devices to be used are listed in the
“Technical Specification” section of this
manual. The power cable supplied with
the welder (Fig. 2 –18) should not be
extended but, if that becomes necessary,
either an identical or greater cross-
section cable should be used according
to the final cable length. All the models
require a three-wire cable (positive,
negative and earth) with a minimum
cross section area equal to 1,5 mm².
