Abstract
PURPOSE:To replenish a wire for exchanging before molten metal solidifies and to prevent weld defects by interupting the conduction of electricity just prior to the using up of the electrode wire under use, removing the remaining wire, replenishing the wire for exhanging and resuming the welding. CONSTITUTION:When the terminal end of an electrode wire 3 which is let off from a wire reel 9 and is under use disengages from a wire reel 9, immediately the conduction of electricity to the wire 3 is stopped; at the same time,a feed roll 11 is run reverse to pull the wire 3 off. On the other hand, an another electrode wire 3' supported near the reel 9 by an auxiliary stand 17 is drawn out and is promptly inserted into the longitudinal through-hole 4A of a consumbale nozzle 4 with leveling rolls 13, feed rolls 11, pressure rolls 12, etc., and when the leading end arrives at the molten metal, the conduction of electricity is resumed. Hence, the fresh wire 3' is continuously replenished before the molten metal in the groove solidifies, and the wasteful leaving-over of the electrode wire is eliminated.
