Fig. 4.15 - Connection of a closed chamber welding head equipped with tacheometry
Connection of a closed chamber welding head equipped with tacheometry (option)4. 4. 8.
Adapters are mounted in the lines from the welding head to the power source/cooling system assembly:
Welding gas.•
Torch rotation.•
Electrode current and water return.•
Earth current and water feed.•
The connection of these adapters to the power source and cooling circuit is identical to those of a liquid cooled
closed chamber welding head.
To avoid damage or poor weld quality it is recommended to readjust the
tachometer of the welding head while putting into operation the equip-
ment.
See as well section “Adjustment of the tachometer” in chapter “Maintenance” of the present paper.
