how can you control the molten puddle in plain stringer bead horizontal welding ?​

Answer:

Your hand can perform a zig-zag, crescent or curlycue technique. Besides allowing a wider bead, weaving is used to control heat in the weld puddle. Besides that, you'll usually want to pause on each side of the weld to achieve good tie in and prevent undercutting of the edges.
