Inventia se refera la un dispozitiv port-electrod care împreuna cu un ansamblu electronic de comanda, legate la orice tip de sursa de sudura, realizeaza mentinerea constanta a lungimii arcului în cazul sudarii electrice manuale cu electrozi înveliti. Dispozitivul, conform inventiei mareste productivitatea prin eliminarea pericolului de întrerupere a aercului si poate fi folosit atît la sudarea în curent continuu cît si la sudarea în curent alternativ.The invention relates to a port-electrode device which, together with an electronic control unit, connected to any type of welding source, achieves constant maintenance of the arc length in the case of electrically welded manual welding. The device according to the invention increases the productivity by eliminating the danger of interruption of the circle and can be used both for direct current welding and for alternating current welding.
