Welding Tractors
AWT Series
Automatic welding with tractors
Welding tractors are effectively used above all for the MIG/
MAG welding of fillet welds in numerous variations. Especially long welding seams can be processed with a welding
tractor in a neat and comfortable way − completely
without manual efforts thanks to the strong magnet and
the precise guide wheels!
AWT series is used above all in the ship and bridge building, crane, machine, plant and steel construction.
