Most spot welders use two points near each other or on each side of the workpiece. The current from the capacitor is probably just absorbed by the relatively large piece of metal. The second video below from [American Tech] shows a 500F capacitor doing spot welding with little more than two wires and it seems to work.
The problem is in how the discharge energy is being directed. Just using the capacitor would cause the charge to flow out as a spark when you got near the point to discharge. To combat this, [Julian] put a microswitch between the capacitor and the copper point he expected to use as the welding tip.
Download the latest version of Windows Media Player. This fully automated Capacitor Lead Attachment Machine welds wire leads (in radial direction) onto the non-inductive type capacitor element. High production rate with high-precision welding can be achieved. It also suits high-variety-low-volume manufacturing.
Is this capacitor bad.
In my experience, capacitors are good, or very bad. Splitting hairs over microfarads is only rarely important. I love primitive industrial capacitor banks made up of hundreds of tin can capacitors with control switch gear. 99% of failed oil filled capacitors puff up like a frozen tin can. Makes diagnosis quick.

Examination of Electrolytic Capacitors for Welding Applications
Capacitors were arranged in a series/parallel array, in which six electrolytic units were placed to allow potential charge voltages of up to 3600 V. The array was also designed to provide a similar capacitance to commercially available film-type units (~1200 μF). The resulting E-cap system was roughly 20% the mass of the film cap counterpart. Welding tests were done using both the film …
