Modified spot welder for Bracelets

A Facebook Reel on making bracelets featured this neat little modified spot welder for joining wire into rings. Instead of normal crab-claw tongs, the spot-welder tongs are parallel, have been thinned down, and have grooves cut into them to fit the radius of the rings.

The operator places the wire in the appropriate size grooves on the tongs, and (presumably by foot pedal?) activates the spot welder. It's MUCH faster than I can do it soldering them together, with the caveat that I'm a rank amateur and a pro is likely faster than me.

I wonder if this would be useful for making chainmail?
