ENCLOSED WELD HEADS OSK 13 S Enclosed weld heads provide complete inert gas protection of the full weld bead circumference (an industry requirement for producing welded joints in electro-polished and hygienic applications). Collets are required for each tube diameter to be welded. Cold wire feed is not possible. Welding will be made after preparation of the tube ends to provide a flat, square face. During welding the weld head remains static, only the rotor carrying the electrode rotates in an ‘orbital’ motion around the tube (90° saw cut, if necessary square off). Advantage: Compact size for use in restricted space environments. Welding equipment MICROFIT WELD HEAD OSK 13 S Gas-cooled weld head for applications with extreme narrow space requirements as e.g. in the semiconductor industry. Specially designed to weld micro-fittings. Unique construction, including specifically directed gas routing to improve gas coverage and material selection resulting in a high duty cycle even without water cooling.
