Description

Die bekannten Blendschutzvorrichtungen tür Elektroschweißer sind in Form eines Handspiegels mit Dunkeischeibe oder als Maske mit Dunkelscheibe und Handabbiendung ausgeführt. The known anti-glare devices for door electric welders are in the form of a hand mirror with a dark disc or as a mask with a dark disc and Hand abduction carried out.

Die Blendschutzvorrichtung nach der Erfindung besteht aus dem Maskenkörper I, in dem zwischen zwei Führungsschienen2 ein Sehschlitz mit Klarscheibe 3 fest angeordnet ist. In den Führungsschienen 2 ist eine Dunkeischeibe 4, die genau über den Sehschlitz paßt, so geführt, daß sie über den Gelenkhebel 5 mit dem Anker 70 eines Relais 7 in Wirkungsverbindung steht. Ein zweiadriges Kabel des Relais 7 endet je durch einen Steckkontakt an der Schweißpistole und durch Haftmagnet oder Federklemme am Arbeitsstick. The anti-glare device according to the invention consists of the mask body I, in which a viewing slit with clear lens 3 is fixed between two guide rails 2 is arranged. In the guide rails 2 is a dark disc 4, which is exactly over the viewing slit fits, guided so that it via the articulated lever 5 with the armature 70 a relay 7 is in operative connection. A two-wire cable from relay 7 ends each with a plug contact on the welding gun and with a holding magnet or spring clip on the work stick.

Bei Nichtschweißen und höherer Spannung ist der Relaisanker 7a angezogen und dreht den Gelenkhebel arm 5, an dessen anderem Ende die Dunkelscheibe 4 befestigt ist, um den Drehpunkt 50 in eine Stellung, welche dem Schweißer den Sehschlitz in der Maske freigibt (im Fall der Zeichnung nach unten). If there is no welding and if the voltage is higher, the relay armature 7a is attracted and rotates the articulated lever arm 5, at the other end of which the dark disk 4 is attached is to the pivot point 50 in a position which the welder can see the slit in the mask releases (in the case of the drawing, downwards).

Beim Schweißen und niedriger Spannung zieht die Zugfeder 6 den Hebelarm vom Anker ab und schiebt damit die Dunloelscheibe nach oben vor den Sehschlitz der Maske. When welding and low voltage, the tension spring 6 pulls the lever arm off the anchor and pushes the Dunlop disc upwards in front of the viewing slit of the Mask.

Elektrische Spannungsänderungen, bedingt durch die verschiedenen Schweißstufen, werden durch Anpassen der Zugfederspannung ausgeglichen. Electrical voltage changes due to the various Welding stages are compensated for by adjusting the tension spring.

Die automatische Abblendung wird eingebaut in eine Gesichtsmaske. The automatic dimming is built into a face mask.

Die Vorteile des Erfindungsgegenstandes bestehen darin, daß ein ununterbrochenes Beobachten der Schweißnaht vor, während und nach dem Schweißen möglich ist, ohne dabei in jeder Arbeitsperiode die Augen zu blenden. The advantages of the subject invention are that an uninterrupted Observing the weld before, during and after welding is possible without dazzling the eyes in every working period.
