Claims (7)

1. Laite langanmuotoisen hitsauselektrodin syöttämiseksi kahdella syöttösuuntaan nähden peräkkäisellä syöttöru1lapari1 la, jonka yhtä rullaa jokaisessa parissa käyttää oma tasavirtamoottori, joka kytken-täelimellä on kytkettävissä syöttöverkkoon, tunnettu siitä, että molempien moottorien (5,6) ahkkurikäämit ovat sarjaan kytketyt.
2. Laite patenttivaatimuksen 1 mukaan, tunnettu siitä, että tasavirtamoottorien (5,6) kierrosluvut pienenevät tyhjäkäyn-nistä täyskuormitukseen enintään 20 %.
3. Laite patenttivaatimuksen 2 mukaan, tunnettu siitä, että tasavirtamoottorien (5,6)·kierrosluvut pienenevät tyhjäkäyn-nistä täyskuormitukseen enintään 5 %.
4. Laite patenttivaatimusten 1-3 mukaisesti, tunnettu elimestä (17) molempien moottoreiden (5,6) kunkin ankkurijännitteen vertailemiseksi annettuun jännitteeseen, joka vertailuelin on järjestetty lähettämään signaalin, kun jonkun moottorin ankkurijännit-teen jännite-ero määrätystä keskiarvosta on annettua arvoa suurempi, joka signaali vaikuttaa kytkentäelimeen (13,14) siten, että moottorit irtikytkeytyvät syöttöverkosta.
5. Laite patenttivaatimuksen 4 mukaan, tunnettu siitä, että kytkinelin on varustettu vaihtokytkimellä (13) ja järjestetty ensimmäisessä asennossa (13a) kytkemään moottorit syöttöverkkoon ja toisessa asennossa (13b) virtapiiriin, joka sisältää jarruvastuk-sen (15,16) moottorien (5*6) vastusjarrutukseen.
6. Laite patenttivaatimuksen 5 mukaan, tunnettu siitä, että kytkentäelimeen (13,14) voidaan vaikuttaa aikavahdilla Μβ), joka on järjestetty ohjaamaan vaihtokytkimen (13) kytkentää molempien asentojen (13a,13b) välillä määrätyn aikavahtiin säädettävän ohjelman mukaisesti.
