With t is arrangementthe forge end velocity could be varied independentlyby the separate adjustnent of the drop and nass of themoving part. Other welding tools were also designedin which springs were used to shoot the wire gripstogether horiiontally; howe\er, these have not beenas satisfactory as the gravitational t^pe. The welding circuit as indic^tec! in figure 37consists of a direct current line or generator G,which charges an elecyrolytio condenser C through ahigh resistance R, Adjustment of the voltage of thecharged condenser is obtained by field control of thegenerator
