MagTrac
never gets tired
− even on long longitudinal welds
Kemppi’s new MagTrac F 61 welding carriage makes the welder’s work
faster and easier. It is a cost-effective and efficient way of increasing
welding productivity in large and small metal fabrication workshops.
When welding large
work pieces the
seams are often
long and straight –
leading to boredom
- or have to be welded in stages. They
require a lot of arc time and do not
really challenge the welder’s skills. It is
precisely this type of welding that offers
the best potential for mechanisation.
Light welding carriages can
significantly improve working conditions
and productivity, as they offer almost
double the speed of manual welding.
In addition, the travel speed and torch
position remain constant for a consistent
quality weld.
Kemppi’s new MagTrac F 61 welding
carriage combines ease of use, accessibility,

quality and efficiency in a
completely new way. It has
been designed as a basic
tool for workshops,
especially for horizontal
fillet welding.
Features designed
for ease of use
Ease of use was the core
idea behind the development
of the MagTrac F 61 carriage. Welding
parameters are transmitted between the
carriage and welding equipment via the
control cable, which is integrated into the
welding gun cable. The carriage gets its
operating power through the same cable,
so only one cable is needed between the
wire feeder and carriage. The fact that
separate transformer and control cables
are not needed makes for a safe working
area and promotes efficiency.
Fixing and adjusting the torch have
also been made as easy as possible: the
stick-out length and torch angle are
adjusted by means of a single fixing
handle.
Settings for the wire feed speed,
welding voltage and other welding
parameters are selected on the carriage
control panel. This makes it easier to
change the settings while welding is in
progress and speeds up work, because
the welder does not need to move from
the carriage to the power source to make
small changes.
The graphical user interface is
another feature that promotes ease of
use. The functions are arranged in a clear
menu structure and can be selected using
a multi-function adjustment knob. Wire
inch and gas test functions are available
for the preparation phase, and an advance

test run can be undertaken
without arc ignition to check
the carriage is operating
correctly. This ensures
successful results.
Valuable data for
quality control
The welding parameters
and heat input can be read
off the display after welding is
finished. The length of the last weld or
distance welded during the day can be
checked from the carriage display. The
carriage display also shows the average
heat input during the last weld. This is
valuable data for the purposes of quality
control and ensuring compliance with the
welding procedure specification.
The MagTrac F 61 carriage can
be used with an MXF type wire feed
unit, which can be placed on a wheeled
undercarriage to provide reach.
Additional reach can be achieved by
using a 15-meter SuperSnake subfeeder,
allowing access even to very tight places
such as ship block structures and main
girders for harbour cranes.
The highest productivity is achieved
by maximising the carriage operating
time and ensuring that preparation and
finishing work is done with purposedesigned
equipment such as the
Kemppi FitWeld, a MIG/MAG machine
developed for tack welding.
