I can't quite figure out the use of that forward arm...seems it's only to align the link vertically for the welding clamps??

PJs there are 2 arms one in front and one in back yes for true centering each alternative link must be rotated opposite of the previous. Other wise the chain would become a twisted ball of a mess for both the welded and yet to be welded links the rapid moving arm to the left shears off the excess due to the forced induction welding.

Never try to tell me it can't be done

PJs, and other interested parties;
Twisted chain...
Here's one making a lighter weight chain than the sample video. Good, but brief, views of pay-out reel and straightening rolls too.
And these are just hardware, don't venture into jewelry chain. Endless!

The thing about chain welding, in this manner, is why doesn’t the whole link heat up? Having a bit of electronics back ground and a bit of welding experience you would think that the power would take the low resistance path.
This also has me wondering how really large chain is done. Could you imagine the power required to weld chain for a super tankers chain.
I have given some thought to the issue of chain welding. I have concluded that it is a matter of least resistance, or in this case shorter distance. Less steel between the "electrodes" or clamps. Surely some current travels the long way but most must take the short path. Seems that this means that there must be extra capacity of current to get a good weld. Just my own musings.
