3. WELDING METHODS
This chapter contains a brief description
of the various welding methods available
and the relevant settings. This chapter
alone does not provide all the information
required for safe and appropriate use of
the unit. Later paragraphs must also be
read carefully (particularly as far as the
torch and cable connections are
concerned).
3.1 MIG/MAG WELDING
(LED 4, Fig.1 ‘on’)
During MIG/MAG welding, a metallic
electrode is melted into a welding pool.
The electrode is continuously fed at
constant speed controlled by the welding
torch. When the wire starts feeding
through and rests on the work-piece an
electric arc is generated. The arc melts
the wire on to the work-piece.
Continuous wire welding enables the use
of higher density currents than when
welding with coated electrodes, therefore
deeper deposits can be left and the joint
can be filled making fewer runs.
Three types of wire can be used:
1. solid wire: always used with shielding
gas – connection row 2, fig 5.
2. flux-core wire for gas welding: the
core of which contains a mineral which is
able to improve the welding
characteristics (always used with gas)
- connection: row 2, fig 5.
3.1.1 MANUAL MIG WELDING
(Fig.1: LED 4 ’on’)
To select this mode, turn knob 5
(Fig.1) to the MIG MAN setting.
While welding, use the welding current
regulator (Fig.1 –8) and the wire-speed
regulator (Fig.1 – 7) as appropriate.
The welding current and the wire speed
must be regulated according to the
thickness of the workpiece. Thicker
workpieces require higher welding
currents and faster wire speeds. For best
results, fine-tune the wire speed while
welding.
The wire speed (m/s) will be displayed for
app. 2 seconds when the knob (fig1 – 7)
is turned.
The quality of the weld can be improved
even further by regulating the electronic
inductance (Fig.1 – 6) in accordance with
the guidelines provided in the paragraph
8.1.
Each time the electronic inductance knob
is turned (Fig.1 - 6), the selected
inductance is displayed on panel 1 for
app. 2 seconds.
3.1.2 SYNERGIC SHORT ARC MIG
WELDING
SHORT ARC MIG WELDING (Fig.1: LED 4 ‘on’)
To select this mode, turn knob 5 (Fig.1)
to the SYNERGIC setting (Al-Mg5 0.8, Al-
Mg5 1, Al-Si12 1, SS 0.8, SG2 0.8 and
Cu-SI3 0.8)
The parameters used for the various
kinds of materials to be welded can be
selected easily when in Synergic Short
Arc MIG Welding mode. When using the
synergic welding function, the thickness
