I need to connect couple LiIon batteries on my project, I am hoping to build some device eg. using a Pb-Acid (car battery) with controlled current and the pulse, or something like, just to do the job.

Has anyone experimented with simple spot-weld, just to weld the Nickel strips in to battery terminals.
 
I saw something similar on e-bay: http://www.ebay.com/itm/Hobby-Mini-Battery-Tab-Spot-Welder-Custom-Built-Machine-for-Small-Projects-110V-/150993408009?pt=BI_Welders&hash=item2327e89009

or http://www.ebay.com/itm/Hand-held-Spot-Welder-Welding-Machine-for-Laptop-Mobile-phone-Battery-220V-A-/261125729341?pt=BI_Welders&hash=item3ccc4e6c3d

How are they control the current and pulse to do the weld?

Any head-start thoughts to buld one.
