Connecting the intermediate drive for welding
1. Connect the 17-pin plug [1] to the power source
2. Connect the Euro plug [2] to the power source
3. Connect the two connectors [3] (blue/red) to the water
quick releases on the power source
4. Connect the Euro plug of the welding torch [4] to the IWF
5. Connect the two connectors [5] (blue/red) to the
corresponding quick releases on the IWF.

Important!
In order to avoid destruction
of plugs and cables, good
electric contact is required
when connecting earth cable
and welding hose to the
machine/IWF.
Please note
Nut and screw in the central
connector of the welding torch may
loosen, even if the central connector
is stored in a heat protection cover.
It is therefore necessary to retighten
in order to maintain good electrical
contact.
