Welding voltage primarily controls the arc length which is the distance between the molten weld pool and the wire filler metal at the point of melting within the arc. As the voltage is increased, the weld bead will flatten out more and have an increasing width-to-depth ratio.
When welding zinc or zinc-coated metals, conical welding nozzles are the recommended nozzle shape to use. The reason being is because zinc produced very large and explosive spatter when being welded, and the clearance provided by the base of the conical welding nozzle allows for it to be reamed more effectively than other nozzle shapes assuming you use a two-stroke reaming process with air blast.
