ABSTRACT:
An adaptor for use with a submerged arc welder is described which includes a wire feed tube and a flux feed tube. The wire feed tube is at least one foot in length and has a first end and a second end. Exterior threads are provided for attaching the first end of the wire feed tube to a wire feeding mechanism of a submerged arc welder. Interior threads are provided for attaching a tip to the second end of the wire feed tube. The flux feed tube is at least one foot in length and has a first end and a second end. The flux feed tube is disposed immediately adjacent and substantially parallel to the wire feed tube with the second end of the flux feed tube adjacent the second end of the wire feed tube. An insulating sheathing covers both the wire feed tube and the flux feed tube, thereby maintaining the wire feed tube and the flux feed tube in parallel relation.
