Smaller Coaxial-View Welding Torch

Abstract

Coaxial-view torch for gas/tungsten arc welding has only two-thirds length and width of its predecessor. Shape and size similar to that of commercial arc-welding torch (Linde HW-27 or equivalent), even though it contains lens system. Collet that holds electrode has unique design allowing greater passage of light. Used in small spaces previously inaccessible, also introduced into production welding operations with minimum of disturbance.
