Introduction<\/h2>\n

Si votre MIG 205GDM (230 V)<\/strong> affiche le EU.02.01<\/strong> En cas d'erreur lors du soudage, ne supposez pas que la machine est d\u00e9fectueuse.<\/p>\n

Dans la plupart des cas, cette erreur est qui n'est pas d\u00fb \u00e0 la source d'alimentation elle-m\u00eame<\/strong>, mais par une charge excessive au niveau du syst\u00e8me d'alimentation en fil, notamment lors de l'utilisation de fil de soudage fourr\u00e9<\/strong>.<\/p>\n

Cet article r\u00e9sume notre exp\u00e9rience en mati\u00e8re de d\u00e9pannage sur le terrain et pr\u00e9sente les causes les plus courantes, les proc\u00e9dures de diagnostic et les solutions.<\/p>\n

\n

Que signifie \u00ab EU.02.01 \u00bb ?<\/h1>\n

D'apr\u00e8s notre \u00e9quipe technique,<\/p>\n

\n

EU.02.01 indique la pr\u00e9sence d'une protection contre les surtensions dans le syst\u00e8me d'alimentation auxiliaire.<\/strong><\/p>\n<\/blockquote>\n

Bien que l'alarme indique le circuit d'alimentation auxiliaire, le v\u00e9ritable facteur d\u00e9clencheur est souvent une charge anormale provenant du moteur du d\u00e9vidoir.<\/p>\n

Lorsque le dispositif d'alimentation rencontre une r\u00e9sistance excessive, le courant du moteur augmente, ce qui d\u00e9clenche le mode de protection du syst\u00e8me de commande.<\/p>\n

\n

\u00c9tape 1. V\u00e9rifier si la machine est r\u00e9ellement d\u00e9fectueuse<\/h1>\n

Avant de remplacer une pi\u00e8ce, effectuez ce test simple.<\/p>\n

Proc\u00e9dure d'essai<\/h3>\n

D\u00e9branchez le fil de soudage.<\/p>\n

Laissez la torche MIG branch\u00e9e.<\/p>\n

Appuyez sur la g\u00e2chette du chalumeau.<\/p>\n

R\u00e9sultat<\/h3>\n

Si :<\/p>\n

    \n
  • la machine fonctionne normalement<\/li>\n
  • le moteur du d\u00e9vidoir fonctionne normalement<\/li>\n
  • aucune erreur EU.02.01 n'appara\u00eet<\/li>\n<\/ul>\n

    dans ce cas, la source d'alimentation fonctionne g\u00e9n\u00e9ralement correctement.<\/p>\n

    Le probl\u00e8me provient tr\u00e8s probablement du syst\u00e8me d'alimentation en fil plut\u00f4t que de l'onduleur.<\/p>\n

    \n

    \u00c9tape 2. V\u00e9rification du syst\u00e8me d'alimentation en fil<\/h1>\n

    C'est la cause la plus fr\u00e9quente de ce probl\u00e8me.<\/p>\n

    V\u00e9rifiez les points suivants :<\/p>\n

      \n
    • La bobine de fil est-elle correctement install\u00e9e ?<\/li>\n
    • Le frein de bobine est-il trop serr\u00e9 ?<\/li>\n
    • Le fil est-il emm\u00eal\u00e9 ou enchev\u00eatr\u00e9 ?<\/li>\n
    • Le fil s'alimente-t-il sans \u00e0-coups lorsqu'on le tire \u00e0 la main ?<\/li>\n
    • La pression du rouleau d'entra\u00eenement est-elle trop \u00e9lev\u00e9e ?<\/li>\n
    • Le diam\u00e8tre du fil correspond-il \u00e0 la rainure du rouleau d'entra\u00eenement ?<\/li>\n
    • La gaine m\u00e9tallique est-elle endommag\u00e9e ou excessivement us\u00e9e ?<\/li>\n
    • La pointe de contact est-elle bouch\u00e9e ?<\/li>\n<\/ul>\n

      Toute r\u00e9sistance suppl\u00e9mentaire augmente la charge du moteur et peut d\u00e9clencher le dispositif de protection.<\/p>\n

      \n

      \u00c9tape 3. Le fil fourr\u00e9 \u00e0 flux n\u00e9cessite une pointe de contact plus grande<\/h1>\n

      L'un des probl\u00e8mes que nous rencontrons fr\u00e9quemment concerne Fil fourr\u00e9 de 1,0 mm<\/strong>.<\/p>\n

      De nombreux utilisateurs installent naturellement un Pointe de contact de 1,0 mm<\/strong>.<\/p>\n

      Cependant, c'est souvent la cause premi\u00e8re.<\/p>\n

      Pourquoi ?<\/h3>\n

      Le fil fourr\u00e9 contient de la poudre de flux.<\/p>\n

      Pendant le soudage :<\/p>\n

        \n
      • le fil chauffe rapidement<\/li>\n
      • le fil tubulaire se dilate l\u00e9g\u00e8rement<\/li>\n
      • le frottement \u00e0 l'int\u00e9rieur de la pointe de contact augmente<\/li>\n<\/ul>\n

        Une pointe de 1,0 mm peut s'av\u00e9rer trop serr\u00e9e, ce qui risque de bloquer le fil.<\/p>\n

        Le moteur d'alimentation tente alors d'exercer une pression plus forte jusqu'\u00e0 ce que le dispositif de protection se d\u00e9clenche.<\/p>\n

        Solution recommand\u00e9e<\/h3>\n

        Pour Fil fourr\u00e9 de 1,0 mm<\/strong>, nous vous recommandons d'utiliser un Pointe de contact de 1,2 mm<\/strong>.<\/p>\n

        Le jeu suppl\u00e9mentaire permet au fil de s'alimenter sans \u00e0-coups, m\u00eame apr\u00e8s la dilatation thermique.<\/p>\n

        Le fil de soudure massif ne se dilate g\u00e9n\u00e9ralement pas de la m\u00eame mani\u00e8re ; il faut donc choisir un Pointe de contact de 1,0 mm<\/strong> Cela fonctionne g\u00e9n\u00e9ralement \u00e0 merveille.<\/p>\n

        \n

        Pourquoi de nombreux fabricants recommandent-ils d'utiliser une pointe de contact surdimensionn\u00e9e ?<\/h1>\n

        Cette recommandation ne s'applique pas uniquement \u00e0 nos machines.<\/p>\n

        De nombreux fabricants de fils fourr\u00e9s recommandent d'utiliser une buse de contact une taille au-dessus<\/strong> chaque fois qu'un enchev\u00eatrement de c\u00e2bles se produit.<\/p>\n

        Parmi les raisons, on peut citer :<\/p>\n

          \n
        • tol\u00e9rance de fabrication du fil fourr\u00e9<\/li>\n
        • dilatation thermique pendant le soudage<\/li>\n
        • r\u00e9duction des frottements \u00e0 l'int\u00e9rieur de l'embout<\/li>\n
        • une meilleure stabilit\u00e9 de l'alimentation<\/li>\n<\/ul>\n

          Cela est consid\u00e9r\u00e9 comme une pratique courante dans le secteur.<\/p>\n

          \n

          \u00c9tape 4. En cas d'utilisation de fil d'aluminium<\/h1>\n

          Si vous soudez de l'aluminium,<\/p>\n

          Assurez-vous que la lampe utilise une rev\u00eatement en T\u00e9flon<\/strong>.<\/p>\n

          Une gaine en acier standard g\u00e9n\u00e8re une r\u00e9sistance excessive et peut facilement entra\u00eener des probl\u00e8mes d'alimentation.<\/p>\n

          V\u00e9rifiez toujours :<\/p>\n

            \n
          • Rev\u00eatement en T\u00e9flon install\u00e9<\/li>\n
          • Rouleau d'entra\u00eenement \u00e0 rainure en U adapt\u00e9<\/li>\n
          • embout de contact adapt\u00e9<\/li>\n
          • pistolet \u00e0 bobine (recommand\u00e9 pour les fils d'aluminium tendres)<\/li>\n<\/ul>\n
            \n

            Autres \u00e9l\u00e9ments \u00e0 v\u00e9rifier<\/h1>\n

            Outre l'alimentation en fil, v\u00e9rifiez \u00e9galement :<\/p>\n

            Connexion \u00e0 la terre<\/h2>\n

            Une mise \u00e0 la terre insuffisante peut entra\u00eener un fonctionnement instable de l'arc.<\/p>\n

            V\u00e9rifier :<\/p>\n

              \n
            • pince de serrage<\/li>\n
            • raccordement par c\u00e2ble<\/li>\n
            • oxydation<\/li>\n
            • bornes mal fix\u00e9es<\/li>\n<\/ul>\n
              \n

              Gun Connection<\/h2>\n

              Veillez \u00e0 :<\/p>\n

                \n
              • Le raccord de la torche MIG est bien serr\u00e9<\/li>\n
              • La connexion au d\u00e9clencheur est s\u00e9curis\u00e9e<\/li>\n
              • aucune broche endommag\u00e9e<\/li>\n<\/ul>\n
                \n

                Conseil de contact<\/h2>\n

                Remplacez la pointe de contact dans les cas suivants :<\/p>\n

                  \n
                • bouch\u00e9<\/li>\n
                • us\u00e9<\/li>\n
                • trop grand en raison de l'usure<\/li>\n
                • endommag\u00e9 par un retour de flamme<\/li>\n<\/ul>\n
                  \n

                  Gaine m\u00e9tallique<\/h2>\n

                  Remplacez la doublure si :<\/p>\n

                    \n
                  • us\u00e9<\/li>\n
                  • contamin\u00e9<\/li>\n
                  • tordu<\/li>\n
                  • trop long<\/li>\n<\/ul>\n

                    Une garniture endommag\u00e9e augmente consid\u00e9rablement la r\u00e9sistance \u00e0 l'alimentation.<\/p>\n

                    \n

                    Pression du rouleau d'entra\u00eenement<\/h2>\n

                    Une pression excessive n'am\u00e9liore pas l'alimentation.<\/p>\n

                    En revanche, il peut :<\/p>\n

                      \n
                    • d\u00e9former le fil<\/li>\n
                    • produire des copeaux m\u00e9talliques<\/li>\n
                    • acc\u00e9l\u00e9rer l'usure de la gaine<\/li>\n
                    • augmenter la charge du moteur<\/li>\n<\/ul>\n

                      R\u00e9glez la pression juste ce qu\u2019il faut pour faire avancer le fil sans qu\u2019il ne glisse.<\/p>\n

                      \n

                        \n
                      • Veillez \u00e0 ce que le fil de soudage reste propre et sec.<\/li>\n
                      • Remplacez r\u00e9guli\u00e8rement les embouts de contact us\u00e9s.<\/li>\n
                      • Remplacez r\u00e9guli\u00e8rement les gaines.<\/li>\n
                      • Utilisez le rouleau d'entra\u00eenement adapt\u00e9.<\/li>\n
                      • \u00c9vitez de trop serrer le frein de bobine.<\/li>\n
                      • Choisissez une pointe de contact adapt\u00e9e au diam\u00e8tre du fil.<\/li>\n
                      • Nettoyez r\u00e9guli\u00e8rement la buse.<\/li>\n
                      • V\u00e9rifiez les connexions \u00e0 la terre avant de souder.<\/li>\n<\/ul>\n
                        \n

                        Conclusion<\/h1>\n

                        D'apr\u00e8s notre exp\u00e9rience en mati\u00e8re de service, EU.02.01 sur le MIG 205GDM (230 V)<\/strong> est g\u00e9n\u00e9ralement il ne s'agit pas d'une panne de l'onduleur<\/strong>.<\/p>\n

                        Au contraire, ce probl\u00e8me est le plus souvent li\u00e9 \u00e0 une r\u00e9sistance excessive au niveau du syst\u00e8me d'alimentation en fil.<\/p>\n

                        Parmi les causes les plus fr\u00e9quentes, on peut citer :<\/p>\n

                          \n
                        1. Taille de la pointe de contact incorrecte<\/li>\n
                        2. Gamme de fils fourr\u00e9s<\/li>\n
                        3. R\u00e9sistance de la gaine m\u00e9tallique<\/li>\n
                        4. Nidification des oiseaux<\/li>\n
                        5. Tension excessive du rouleau d'entra\u00eenement<\/li>\n
                        6. Frein de bobine trop serr\u00e9<\/li>\n
                        7. Installation incorrecte du c\u00e2blage<\/li>\n<\/ol>\n

                          Une v\u00e9rification syst\u00e9matique de ces \u00e9l\u00e9ments permet de r\u00e9soudre la plupart des probl\u00e8mes sans avoir \u00e0 remplacer les composants \u00e9lectroniques.<\/p>","protected":false},"excerpt":{"rendered":"
