[Lab] nickel strips for battery packs

[siggen]

Hi

I've made a micro spot welder from a rewired microwave-oven transformer, 
with an Arduino to phase-control its primary. The results look good on 
an oscilloscope. My welder melts metal more or less controllably.

However, to do something remotely useful I need materials.

Is there a Canadian source of soft nickel strip for building battery 
packs? There is this .25" x .005" x 25' roll at 
http://www.sunstonespotwelders.com/spot-welding-accessories-nickel-strips.php. 
The same source has RWMA II welding electrodes. But shipping this from 
the U.S. doubles its price, then involves customs.
