Abstract
Entry of molten lead into the space between the electrode plates from the gap between welding jig,and electrode plate lead,is prevented by a construction of pouring nozzle,in which the flow speed and temperature of the molten lead when molten lead is poured into the recess of the welding jig,are lowered. Also, admixture of oxide and/or scum is eliminated by discharging the molten lead from the bottom of reservoir,. Furthermore, reliable joining of strap,, electrode plate leads,and pillar electrode,is achieved by prioritising melting of electrode plate leads,, pillar electrode,and the vicinity thereof by plasma welding.
