Spot welding 1.5V battery tabs Answered

I'm trying to spot weld battery tabs for rebuilding a Nicad battery.  I'm using a 12 volt SLA battery for power.  When I touch the leads they get so hot they burn the tabs, but the weld doesn't penetrate the battery.  What am I doing wrong?

.  You need to put pressure on the weld while welding. See second sentence.
