Wire speed feed is automatic
May 1st 2008 Butters AMT has introduced a
range of MIG Synergic Auto
machines, launching with 'Auto'
versions of its single-phase AMT
271 and three-phase AMT 360
machines. The new machines have
Butters AMT's traditional MIG
machine bases with 'soft arc'
technology (copper-based
transformers and chokes) with
control electronics, a user-friendly
touch-pad and a digital display to
simplify machine operation; for
professional and semi-professional
users.
In Auto mode, the user sets the
type of material to be welded, wire
diameter, type of gas to be used
and desired output voltage (in
accordance with the thickness of
the material to be welded). The
machine automatically sets the
wire feed speed. Once welding
starts, wire feed speed is
automatically regulated to maintain
a constant arc length. "The
automatic regulation of the arc
length means that operators with
little experience can produce
uniform and spatter-free quality
welds on every job – which means
little if any rework may be
required," explains Julian Knowles
Butters AMT's technical director.
"The machines also
require little
setting up, so
productivity
can remain
high."
The Auto
machines 'assume' the
work piece is level, but a trim dial
allows for the adjustment of the
(average) wire feed speed when
the work piece is positioned
differently, such as angled, upright
or overhead. The AMT 271 Auto is
suited to light to medium industrial
applications and the AMT 360 Auto
is suited to medium to heavy
industrial applications. More articles from Butters A.M.T. Ltd: |
