2.3 Welding method
Submerged--arc welding
For submerged--arc welding, an A2 Multitrac of type A2 TFE1 UP light duty is used,
with a Ø 20 mm connector which permits a load of up to 800 A (100%) or 1000 A
(60%).
The welding head can be equipped with feed rollers for single or twin wire welding
(twin--arc). A special knurled feed roller is available for flux--cored wire, which
guarantees even wire feed without the risk of deformation due to high feed pressure.
MIG/MAG welding
For MIG/MAG welding, an A2 Multitrac A2 T GE1 is used, which has a maximum
rated load of 600 A. The welding head is water cooled, with the cooling water
supplied by hoses from connections intended for the purpose.
Connection instructions for submerged--arc and MIG/MAG welding are shown in the
connection diagram, see pages 22 and 23.
