Arc welding equipment - Part 6: Limited duty equipment

IEC 60974-6:2010 specifies safety and performance requirements applicable to limited duty arc welding and cutting power sources, and auxiliaries designed for use by laymen. Electrically powered equipment is intended to be connected to the single phase public low-voltage supply system. Engine driven power sources can not exceed output power of 7,5 kVA. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:
- extension of the scope;
- amendment of the title;
- touch current at fault condition (see 6.3.7);
- new definition of thermal requirements based two independent devices, one for thermal protection and one for thermal control (see 7.1);
- new definition for thermal performances at 20 °C (see 7.2);
- thermal safety requirements are based on operating temperature for normal condition and maximum temperature in overload condition (see 7.4);
- addition of abnormal operation test for thermal control device (see 10.4);
- new requirement for auxiliaries (see Clause 16);
- new rating plate definition (see Clause 17);
- introduction of new mandatory warning symbols (see 12.1.117.3, Box 17b) and 19.2);
- induced changes due to publication of IEC 60974-1:2005.
This publication is to be read in conjunction with IEC 60974-1:2005.

Lichtbogenschweißeinrichtungen - Teil 6: Schweißstromquellen mit begrenzter Einschaltdauer

Matériel de soudage à l'arc - Partie 6: Matériel à service limité

La CEI 60974-6:2010 spécifie les exigences de sécurité et de performance qui s'appliquent aux sources de courant de soudage et de coupage à l'arc à service limité et dispositifs externes conçus pour être utilisées par des non professionnels. Le matériel électrique est prévu pour être connecté à un système d'alimentation public à basse tension et monophasé. Les sources de courant de soudage à moteur thermique ne peuvent pas dépasser une puissance de sortie de 7,5 kVA. Cette deuxième édition annule et remplace la première édition parue en 2003. Elle constitue une révision technique. Les modifications techniques majeures par rapport à l'édition précédente sont les suivantes:
- élargissement du domaine d'application;
- changement du titre;
- courant de contact en cas de défaut (voir 6.3.7);
- nouvelle définition des exigences thermiques basée sur deux dispositifs indépendants, l'un pour la protection thermique et l'autre pour la commande thermique (voir 7.1);
- nouvelle définition pour performances thermiques à 20 °C (voir 7.2);
- les exigences pour la sécurité thermique sont basées sur la température de fonctionnement à l'état normal et la température maximale à l'état de surcharge (voir 7.4);
- ajout de l'essai de fonctionnement anormal des dispositifs de commande thermique (voir 10.4);
- nouvelle exigence pour les dispositifs auxiliaires (voir Article 16);
- nouvelle plaque signalétique (voir Article 17);
- introduction de nouveaux symboles d'avertissement obligatoires (voir 12.1.1, 17.3, case 17b) et 19.2);
- modifications induites en fonction de la pubilcation de la CEI 60974-1:2005.
Cette publication doit être lue conjointement avec la CEI 60974-1:2005.

Oprema za obločno varjenje - 6. del: Oprema za omejeno uporabo (IEC 60974-6:2010)

Ta del IEC 60974 določa varnostne zahteve in izvedbene zahteve, ki veljajo za obločno varjenje z omejeno uporabo in vire rezalne moči ter za dodatno opremo, načrtovano za uporabo laikov. Električno gnana oprema je namenjena povezavi z enofaznim javnim oskrbovalnim sistemom nizke napetosti. Gnani viri električne energije ne smejo preseči izhodne moči 7,5 kVA. Ta del IEC 60974 ne velja za vire obločnega varjenja in rezalno moč, ki jo potrebujejo za delovanje: – naprave za obločno varjenje in stabiliziranje; – sistemi za hlajenje s tekočino; – plinske konzole; – trifazna vhodna oskrba in tisti, namenjene le industrijski in strokovni uporabi. Ta del IEC 60974 ne velja za vire obločnega varjenja in rezalno moč ter pomožno opremo, ki se uporablja pri: – mehansko vodenih uporabah; – postopku obločnega varjenje pod praškom; – plazemskem postopku žlebljenja; – postopku plazemskega varjenja; ti so zajeti v drugih delih IEC 60974.
