Semiautomatic welding spool extension

Many roll empty bobbins for wire welding semiautomatic device. I wrapped both ropes and wire on these bobbins, and then I got the idea to attach a wire with a plug on both sides of the outlet (even the inside ones fit) and now I get a conveniently portable and stored “carry”. Of course, we make a knot inside, so as not to pull out the wire.
