So braid-brake hose act like battery-cable and conducts power from one end to other?
If you were to measure resistance end-to-end, would you find connectivity between 2 ends?
Now, let's take closer look at this torche:
From video I posted earlier:

Little more than 1/2 way through, you'll see same rubber-coated end of torche hose:
And he pulls it out and shows you end... METAL!!!
What do you think chances are that if you were to measure resistance between connector end of that cable and collet holder, that there would be continuity?
Here's close-up of that Vevor welder you linked to:
What material is connector that "TIG Torch" connects to? Why would that be? What's that hole in centre for?
You never answered this question:
Did you ever connected TIG torche to your welder and used it for regular steel welding???
