lower end of your
burning lead strip close to and over the center of the hole, and melt
in the lead, being sure to keep the top of the post and the inner
surface of the hole in the connector melted so that the lead you are
melting in will flow together and unite. Melt in lead until it comes
up flush with the upper surface of the connector. Then remove the
flame. This completes the first stage of the welding process. Now
repeat the above operation for each post and terminal.

It is essential that the top of the post and the inner surface of the
hole in the connector be kept melted as long as you are running in
lead from the strip of burning lead. This is necessary to have all
parts fuse together thoroughly. If you allow the top of the post, or
the inner surface of the hole in the connector to chill slightly while
you are feeding in the lead, the parts will not fuse, and the result
will be a poor Joint, which will heat up and possibly reduce the
current obtained from the battery when the starting switch is closed.
This reduction may prevent the starting motor from developing
sufficient torque to crank the engine.

When the joint cools, the lead will shrink slightly over the center of
the posts. To finish the welding, this lead is to be built up flush or
slightly higher than the connector. Brush the tops of the post and
connector thoroughly with a wire brush to remove any dirt which may
have been floating in the lead. (Dirt always floats on top of the
lead.) Soften the burning flame so that it is just barely beginning to
hiss. Bring the flame down over the center of the post. When this
begins to melt, move the flame outward with a circular motion until
the whole top of post and connector begins to melt and fuse. If
necessary run in some lead from the burning lead strip. When the post
and connector are fused, clear to the outer edge of the connector,
raise the flame straight up from the work.

You will save time by doing the first stage of the burning on all
posts first, and then finish all of them. This is quicker than trying
to complete both stages of burning on each post before going to the
next post. The object in the finishing stage is to melt a thin layer
of the top of post and connector, not melting deep enough to have the
outer edge of the connect
