COMMISSIONING - GENERAL DETAILS
WARNING:
EXTERNAL INTERFERENCE CAUSED BY TIG WELDING
USING HIGH FREQUENCY (HF)
The high frequency used for contact-free ignition with DC TIG
welding, can interfere with the operation of insufficiently shielded
computer equipment, EDP centres, industrial robots, computer-
controlled processing equipment and measuring stations, even
causing complete system breakdown. Also, TIG welding in resi-
dential areas may interfere with electronic telephone notworks
and with radio and TV reception.
ELECTRICAL WORK, CHANGING THE FUSES ON THE AUXI-
LIARY TRANSFORMER, OR FITTING/CHANGING THE PO-
WER PLUG, MAY ONLY BE CARRIED OUT BY A QUALIFIED
ELECTRICIAN!
The Transtig 330/450 may be operated as standard on a
mains voltage of 3x380V / 400V or 415V, provided that the
auxiliary transformer has been connected correctly for the
operating voltage in question (Fig. 5). Yellow-green lead =
protective earth conductor (PE). The other conductors, L
1
, L
2
and
L
3
, are connected to three phases of the mains plug. The phase
sequence is not important. Since the introduction of EuroNorm
IEC 38 in May 1987, mains voltage has been defined as 400V
throughout Europe.
The machine is connected in our works for 400V! This means
that it may also be run on the 3x380V mains (Fig. 6), thanks to its
tolerance range of +/- 10. Machines connected for voltages other
than 3x400V are labelled with a sticker reading: "WARNING!
MACHINE IS CONNECTED AT ...........V!"
Where the mains voltage is 3x220V, 3x440V or 3x500V, it must
first be fed through a FRONIUS ancillary autotransformer. This
may be retrofitted at any time, and can be fitted between the
trolley and the power source.
SETTING-UP INSTRUCTIONS
Open-air operation
As indicated by its protection category, the machine may be set
up and operated in the open air. However, the built-in electrical
parts must be protected from direct wetting caused by e. g.
external wet cleaning etc.
Cooling air
The machine must be set up in such a way that the cooling air
can enter and leave the machine freely through the louver-type
slots at the front and rear of the machine respectively.
Dust
Make sure that any metal dust caused by e. g. grinding work is
not sucked into the machine by the cooling fan.
Ambient temperature
The power source must be positioned well away from such
sources of heat as radiators, heating or annealing furnaces,
direct hot sunshine etc., which would raise its temperature still
further. The technical data given here in are for a max. ambient
temperature of +40°C.
WHEN HOISTING THE CRANE, MAKE SURE:
- that the chains and cables are attached to all the hoisting
points and are as near vertical as possible.
to prevent accidents, take the gas cylinder off the machine
before hoisting it.
