CONNECTION
- Before making the electrical connections between
the welding machine and the line switch, ensure
that the switch is turned off .
- The distribution panel must comply with the
regulations in force in the country of use.
- The mains system must be of the industrial type.
- For longer connecting cables, increase the lead
section as required.
- When using long extension cables, the cable core
diameter size is relevant to the machine
requirements for achieving optimum performance.
- The power input supply socket from the mains
voltage supply, must have a suitable switch
provided together with a 'slow-burning' type
fuse(s).
- In the event of damage to the power cable,
replacement or repair must be performed by a
qualified person at an approved service centre.
3-PHASE CONNECTION
To connect the machine to a standard 3 phase power
source see the scheme pag.35.
1-PHASE CONNECTION (only TIG 453S AC/DC)
This unit can be connected to input power 230 VAC 1
Phase without removing cover to relink the power
source. To do this see the scheme pag.35:
EARTHING
- To ensure user protection the welding machine
must absolutely be correctly connected to the earth
system
(INTERNATIONAL SAFETY
REGULATIONS).
- It is indispensable to provide good earthing by
means of the yellow-green lead in the power cable,
in order to avoid discharges due to accidental
contacts with earthed objects .
- The chassis (which is conductive) is electrically
connected with the earth lead; if the equipment is
not suitably connected to earth it may cause
electric shocks which are dangerous for the user.
