Abstract
A welding apparatus in combination with a submerged arc welding head and a plurality of welding ribbons having an adapter plate attached to the welding head and a vertical brace attached to the adapter plate. A plurality of jaw assemblies are pivotally connected to the vertical brace. The welding ribbons pass through a ribbon guide mounted to the adapter plate and pass through the jaw assemblies. By rotating a plurality of cams, which are in contact with the jaw assemblies, the relative angle between the jaw assemblies and ribbons may be adjusted. By rotating a pivot rod the distance between the jaw assemblies and ribbons may be adjusted.
