3.1 START-UP. PREVIOUS OPERATIONS.
In principle, the connection of the system should be done as indicated in the previous chapter and before
performing a final start-up of the system, perform the following operations
:
1º)
Make sure the mains voltage coincides with that established in the machine
.
2º)
Connect supply cable to the relative electrical power outlet
.
3ª)
Check that the gas bottle is well protected by the bottle-holder system, and above all, check that the safety
chain is properly placed
.
4º)
Install the pressure reducing valve and connect gas hose checking that there are no leakages, throughout
the whole circuit
.
5º)
Fit the relative adapter onto the wire reel and fit this assembly into the wire reel support axle
.
6º)
Depending on the wire diameter, fit the groove of the correct driving wheel
.
7º)
Fit the wire into the driving system
. Do not abuse the thread pressure lever, because if it is too tight,
loops may occur, and if the lever is too loose, the thread may slip. Once the wire has been
inserted, you can connect the torch, as the machine is ready to start welding.
