So is this the first of it's kinda, aka welded joint?
A bit worried here, that joint gets hot, gets drenched with e-juice and beign a steam machine gets inhaled directly to lugns a lot, not so eager to give it a go.
as to the welded joints you can also get coils that are( nr-r-nr) which are made of three bits of wire welded/fused joints coil is resistance wire and the legs are non resistance wire
