It is the wire that creates the arc isn't it?
Yes it is the wire that creates the arc, the shroud doesn't matter if it touches the metal as it's insulated from the end of the torch.
Pull the shroud off, slight clockwise twist and you will see it has a smaller diameter sleeve inside that is insulated from the outer shroud by a ring of asbestos type insulation.

What model welder is it ?
