Product Description

Hobart Brothers Company (Troy, Ohio — founded 1917; today part of ITW Welding, later merged into ESAB and Miller-related welding groups) was through the 20th century a leading U.S. manufacturer of arc-welding power sources, welding electrodes, and welding accessories — including gas tungsten arc welding (GTAW / TIG) torches used across aerospace, nuclear, chemical, petrochemical, and precision-fabrication industries through the asbestos era.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Hobart Brothers TIG welding torches contained asbestos in the torch’s high-temperature insulating components — including the ceramic cup (gas nozzle) at the torch tip, the insulating gasket seal between the collet body and torch head, and the torch-body internal insulating sleeve — and that TIG welders and welding-equipment service technicians who reassembled Hobart TIG torches, replaced ceramic cups, or ground and dressed damaged cups were exposed to airborne asbestos fibers.

TIG torch ceramic cups run directly in the arc zone at extreme temperatures; the cup must be replaced whenever it cracks, spalls, or accumulates weld spatter. Cup replacement requires unscrewing the used cup from the torch head, discarding the fractured ceramic material, and screwing on a fresh cup — each of which disturbs the cup’s asbestos-composite content. Welders who dressed the tip of a chipped cup on a grinder released respirable fibers directly into their breathing zone.

Hobart Brothers Company has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.
