18 MAN. PS 254 EN – Ind. 2
2.3.6. Connection of a manual torch with
double command
! Connection of the electrode current
cable
Connect the current cable on the "-" terminal
with the quick connector, locking it by a short
rotation to the right.
! Connection of the ground cable
Connect the ground cable to the "+" terminal
surrounded by a red ring. Connection is made

2.3.7. Connection of a liquid cooled
closed chamber welding head with
tachometry (optional)
Adapters are mounted between every circuit
from welding head and connections on power
source :
• Gas circuit.
• Torch rotation.
• Electrode connection and water return.
• Workpiece connection and water outlet.
Connections of these adapters on the power
source are identical with those of a liquid
cooled closed chamber welding head.
