Installation and connection
4.3 Electrical
connection
DANGER! Electrical voltage!
Connection to the mains and maintenance must be carried out in accordance with VDE
regulations! Defective or damaged parts on the torch or hose assembly must be replaced
immediately!
Check that the voltage indicated on the type plate corresponds to the nominal voltage of your voltage network.
The device may only be used with sockets and extension cords with earthing contact plugs that have been
installed by an authorised specialist.
The fuse protection of the supply lines to the mains sockets must comply with the regulations. According to
these regulations, only fuses or circuit breakers corresponding to the cable cross-section may be used.
Overprotection may result in a line fire or damage to the building.
Before plugging in the mains plug, the mains voltage selector switch must be set to zero.
Use of extension cables
If possible, avoid use of extensions! For some applications, extension cable must be used to reach the workplace.
To ensure full performance, the following table must be observed, in which the cross-sections of the conductors
are given as a function of length.
Length of extension cable
Minimum cross section of the cable
10 Meter

NOTE:
If the length deviates from this, the cross-section must be adjusted proportionally.
4.4 Compressed
air
connection
Connect the compressed air source to the filter pressure regulator located at the rear of the unit. Make sure that
there is no water, condensation or oil in the compressed air. If this is the case, additional filtration, such as a
dehumidification filter, is necessary. The recommended operating pressure is 5.0 bar with an air requirement of
250 l/min. For the plasma cutter BARRACUDA 45i, 4.0 bar with an air requirement of 100 l/min and for the plasma
cutter BARRACUDA 65i, 105i and 125i 5.0 bar with an air requirement of 250 l/min.
To flush the system, please press the compressed air test button (Fig. 5-3).

Connection of the plasma torch
BARRACUDA 45i
Insert the plug of the torch into the corresponding plug-in coupling. Make sure that the spring of the plug matches
the groove of the plug-in coupling. Use the mandrel provided to press the safety catch (arrow, Fig. 4-2) on the
right-hand side of the coupling. Now turn the union nut of the plug clockwise until it is tightened.
To release the torch, press the safety catch on the right-hand side of the coupling with the mandrel provided and
turn the union nut of the plug counterclockwise until the plug can be pulled out.
