Welding packages
September 1st 2007 Three ESAB A2 Multitrac
submerged arc welding
packages have been
supplied to William Hare for
the fabrication of substantial
structures destined for the
Paddington section of
London's Crossrail project.
The A2 Multitrac is a fourwheel
drive tractor that can
be used for submerged arc
welding (SAW) or gas metal
arc welding (GMAW) in a
single- or twin-wire
configuration. The single-
wire SAW models bought
by William Hare have
ESAB's A2/A6 process
controllers type PEH and
are connected to ESAB LAF
1000 power sources. The
tractor units have flux
recovery systems.
Although robust, the A2
Multitrac is easily moved
from one welding station to
the next. Once in place, it
can be rapidly set up and, if
required, welding parameters
can be recalled from the
PEH controller's memory
(up to 10 sets can be
stored). The controller's
digital display and push-
button interface are said to
be easy to use. The LAF
1000 power source is rated
at 1000A at a 60% duty cycle
and is also user-friendly. More articles from ESAB Group UK Limited: |
