Abstract

A welding head assembly comprises several heads each having an electrode and an adjustable support for supporting the assembly in relationship to a workpiece. The support has a device for advancing and withdrawing the assembly as a unit so that this is vertical to the workpiece welding zone. The assembly also has a device for advancing or withdrawing each welding head vertically in relationship to the welding zone.
