PERSONAL PROTECTION
As a basic safeguard, insulating gloves should be worn on both
hands when welding. These protect against electric shocks
(from the opencircuit voltage of the welding current circuit),
harmful rays (heat and ultra-violet rays), and against splashes
of red-hot metal or slag.
Solid, insulating footwear should be worn, which should also
insulate the wearer in wet conditions. Ordinary shoes are not
suitable as falling globules of molten metal can cause burns.
Suitable clothing must be worn - NO synthetics!
Do not look at the arc with unprotected eyes. Use only
protective welding shields with the prescribed type of safety
glass. As well as heat and light rays, which may cause dazzling
or burns, the arc also gives off ultra-violet rays. These are
invisible, and if the welder is insufficiently protected against
them they can cause conjunctivitis, which only makes itself felt
several hours later and is extremely painful. Quite apart from
this, ultra-violet rays have the same effect as sun-burn on
unprotected parts of the body.
Welder´s mates or persons in the immediate vicinity of the arc
must also be made aware of the danger and provided with the
necessary protective apparatus; if necessary, protective
screens must be erected.
Care must always be taken to provide sufficient fresh air,
especially when welding in enclosed spaces, since smoke and
harmful gases are produced during the welding process.
Containers which have been used to store gas, fuel, mineral
oils or other such substances must not be welded, even if they
have been standing empty for a long time, since there is a high
risk of explosion from any residue.
Special regulations apply to enclosed spaces where there is a
danger of explosion.
Welds which are exposed to heavy stresses and which have to
fulfil strict safety requirements must only be performed by
particularly well-trained and experienced welders. Examples
include things such as pressurised containers, track rails,
trailer couplings, and so on.
CARE AND MAINTENANCE
Under normal operating conditions the TRANSTIG 330/450
requires a minimum of care and maintenance. However, to
ensure continued trouble-fee operation of your machine for year
to come, a certain amount of basic maintenance must be carried
out.
Check the mains plug and mains cable, and the welding torch
and earth connection, for signs of damage from time to time.
Once or twice a year, unscrew the welding machine casing.
CAUTION:
SWITCH OFF THE MACHINE AND PULL OUT THE PLUG
FIRST!
Clean out the inside of the unit using dry compressed air (be
careful - blowing compressed air directly ontol electronic
components from too close a distance may damage them!)
IMPORTANT on water-cooled machines:
Check that the torch connections are watertight
Check the level and quality of the cooling water regularly.
(Top up or change if necessary!)
ONLY TOP UP WITH CLEAN TAP WATER!
Keep an eye on the water return-flow in the coolant reservoir.
If there is no cooling water and the torch is used, this normally
results in serious damage to the torch body or the hose pack
(i.e. no claims possible under warranty!) For details on the
alcohol admixture ratio necessary to protect the machine
against sub-zero ambient temperatures, see p. 36 and the
instruction manual for the torch in question.
EXCHANGING THE TC 3 ELECTRONIC MODULE Fig. 45 - 47
This should only be carried out by a FRONIUS customer
service technician or by trained specialist personnel.
Caution: Switch off the machine and pull out the plug first!
Deserrer et retirer le bouton de commande de sélecteur d'am-
orçage HF
Dévisser les 4 vis de fixation et retirer le tiroir éctronique.
Undo plug-in connection X2 (at rear of TC3 control unit)
Before fitting the new control unit, adjust the ampere range to
suit the power source; depending on the type of machine, it is
necessary here to set the coding switch to the correct value, as
shown in Fig. 47.
CAUTION: When fitting the new control unit, be sure to plug in
the connection the right way round (look out for the plug tab).
The machine may only be started up when the TC 3 electronic
module is properly mounted on the machine with all 4 fixing
screws. No warranty claims will be accepted for any damage
done to electronic componentry as a result of the HF being
insufficient shielded!
