  • Patent number: 4757180
    Abstract: The invention relates to a transport device for welding wire feed for welding equipment, in particular arc sheild-gas welding tools on manipulators. The welding wire is transported from a magazine or reel with the aid of two separate drives. The main drive determines the feed and it is mounted near the application welding die, while the auxiliary is arranged spaced therebehind. The motor of the main drive is controlled to a constant speed corresponding to the selected feed, while the auxiliary drive acts on the welding wire with slip. The motor of the auxiliary drive is also controlled to a constant speed, the speed adjustment of the drives being, however, control-technologically connected for maintenance of a certain difference of the transport speeds.
