An arc welder is ALWAYS a short circuit when there is a plasma arc
struck up, and during its entire duration. There is virtually no
difference between the resistance of the plasma, and a dead short.

Then from where comes the energy to do the welding?


The plasma, and the molten steel are a resistor. The current going
though said resistor gets dissipated as heat at the resistor site,
which is the tip, and the work (weld) location.
