per danni conseguenti a installazione non corretta, incuria o impiego in modo anormale.
AVVERTENZA: Questo simbolo indica che occorre seguire le istruzioni per evitare seri infortuni,
anche mortali, alle persone o danni a questa macchina. Proteggete voi stessi e gli altri dalla
possibilità di seri infortuni anche mortali.
LEGGERE E COMPRENDERE LE ISTRUZIONI: Leggere e comprendere questo manuale prima di
far funzionare la macchina. La saldatura ad arco può presentare dei rischi. La mancata osservanza
delle istruzioni di questo manuale può provocare seri infortuni, anche mortali, alle persone o danni alla
macchina.
LA FOLGORAZIONE ELETTRICA E’ MORTALE: Le macchine per saldatura generano tensioni
elevate. Non toccate l’elettrodo, il morsetto di massa o pezzi da saldare collegati alla macchina
quando la macchina è accesa. Mantenetevi isolati elettricamente da elettrodo, morsetto e pezzi
collegati a questo.
MACCHINA CON ALIMENTAZIONE ELETTRICA: Togliere l’alimentazione con l’interruttore ai fusibili
prima di svolgere operazioni su questa macchina. Mettere la macchina a terra secondo le normative
vigenti.
MACCHINA CON ALIMENTAZIONE ELETTRICA: Ispezionare periodicamente i cavi di
alimentazione, all’elettrodo e al pezzo. Se si riscontrano danni all’isolamento sostituire
immediatamente il cavo. Non posare la pinza portaelettrodo direttamente sul banco di saldatura o
qualsiasi altra superficie in contatto con il morsetto di massa per evitare un innesco involontario
dell’arco.
I CAMPI ELETTRICI E MAGNETICI POSSONO ESSERE PERICOLOSI: Il passaggio di corrente
elettrica in un conduttore produce campi elettromagnetici. Questi campi possono interferire con alcuni
cardiostimolatori ("pacemaker") e i saldatori con un cardiostimolatore devono consultare il loro medico
su possibili rischi prima di impiegare questa macchina.
CONFORMITÀ CE: Questa macchina è conforme alle Direttive Europee.
FUMI E GAS POSSONO ESSERE PERICOLOSI: La saldatura può produrre fumi e gas dannosi alla
salute. Evitate di respirare questi fumi e gas. Per evitare il pericolo l’operatore deve disporre di una
ventilazione o di un'estrazione di fumi e gas che li allontanino dalla zona in cui respira.
I RAGGI EMESSI DALL’ARCO BRUCIANO: Usate una maschera con schermatura adatta a
proteggervi gli occhi da spruzzi e raggi emessi dall’arco mentre saldate o osservate la saldatura.
Indossare indumenti adatti in materiale resistente alla fiamma per proteggere il corpo, sia vostro che
dei vostri aiutanti. Le persone che si trovano nelle vicinanze devono essere protette da schermature
adatte, non infiammabili, e devono essere avvertite di non guardare l’arco e di non esporvisi.
GLI SPRUZZI DI SALDATURA POSSONO PROVOCARE INCENDI O ESPLOSIONI: Allontanare
dall'area di saldatura quanto può prendere fuoco e tenere a portata di mano un estintore. Gli spruzzi
o altri materiali ad alta temperatura prodotti dalla saldatura attraversano con facilità eventuali piccole
aperture raggiungendo le zone vicine. Non saldare su serbatoi, bidoni, contenitori o altri materiali fino
a che non si sia fatto tutto il necessario per assicurarsi dell'assenza di vapori infiammabili o nocivi.
Non impiegare mai questa macchina se vi è presenza di gas e/o vapori infiammabili o combustibili
liquidi.
I MATERIALI SALDATI BRUCIANO: Il processo di saldatura produce moltissimo calore. Ci si può
bruciare in modo grave con le superfici e materiali caldi della zona di saldatura. Impiegare guanti e
pinze per toccare o muovere materiali nella zona di saldatura.
