Title
(EN) WELDING SYSTEM FOR TIG WELDING
(FR) SYSTEME DE SOUDAGE POUR SOUDAGE TIG
Abstract
(EN)
Tig welding with electronic operating scrape ignition circuit, which by lifting the welding electrode (6) is activated by an idle voltage control (7) in a way so the welding current shortly is lifted over the basic current. Hereby you obtain an establishing of a welding voltaic arc without using high tension. Because of the low welding current in the starting moment - under 10 A, the system is very fitted for welding thin plates.
(FR)
Soudage TIG avec circuit électronique d'allumage de décapage lequel, en relevant l'électrode de soudage (6), est activé par une commande de tension à courant déwatté (7) de telle manière que le courant de soudage dépasse brièvement le courant de base. De cette manière on obtient un arc voltaïque de soudage sans utiliser une tension élevée. Grâce à la faible intensité du courant de soudage au moment du départ, intensité inférieure à 10 A, le système est particulièrement adapté au soudage de plaques minces.
