The invention originates in the field of resistance welding technology,
among other means by means of welding robots 1, for use in roll seam
welding, projection welding or spot welding, and has to do with
accommodating components for operation inside the housing 2 of the
welding tongs. Taking the demands in terms of weight into account, the
object of the invention is to achieve the most effective possible
utilization of space for the housing 2 of the welding tongs carried by
the welding robot. The housing 2 of the welding tongs is given a module 3
for this purpose. This module 3 includes modular components that are
relevant to performing the welding process that is monitored by the
welding controller.
