An arc welding torch arrangement for performing internal welds by means of a non-consumable electrode that can be inserted into a tube to be welded and that can be rotated therein so that the electrode is forced to move in a circular path about the axis geometry of the tube, in which to allow the evacuation of excessive heat from the electrode, the latter is secured to a block of material of high thermal conductivity and passages are provided inside the body of the torch for circulation to and from the block of a coolant liquid, the block being of limited length so that the coolant arrives near the electrode.
