This specialized dual-scale gauge was produced by the Simpson Electric Company (or its predecessor, Jewell) for use with arc welding equipment, likely made for Lincoln Electric \"Stable Arc\" welders.\u003c\/p\u003e\u003cp\u003eDetails\u003c\/p\u003e\u003cp\u003eManufacturer: Simpson Electric Company, which acquired the original manufacturer, Jewell Electrical Instrument Company, in the early 1930s.\u003c\/p\u003e\u003cp\u003ePurpose: The meter is specifically branded \"Shield-Arc\", a trademark of the Lincoln Electric Company for their arc welding equipment. This gauge would have been installed on the control panel of a vintage arc welder.\u003c\/p\u003e\u003cp\u003eMeasurements: It measures both Volts (on the upper scale, 0-50 V with a \"50 M.V.\" indicator) and Amperes (on the lower scale, 0-400 A).\u003c\/p\u003e\u003cp\u003eOperation: A button labeled \"PRESS BUTTON FOR AMPERES\" allows the operator to switch between the voltage and amperage readings using the single needle.\u003c\/p\u003e\u003cp\u003eEra: Given the acquisition of Jewell by Simpson in 1931 and the general style, these meters are typically from the 1920s to 1940s. \u003c\/p\u003e\u003cp\u003eThis is a very specific, industrial vintage instrument used for monitoring high-power welding operations.\u003c\/p\u003e\u003cp\u003eSelling as pictured.\u003c\/p\u003e\u003cp\u003eMore than welcome to pick up at shop in Butler PA \u0026amp; save shipping.\u003c\/p\u003e\u003cp\u003e020226-JM6\u003c\/p\u003e","brand":"cyclewarehouse.online","offers":[{"title":"Default Title","offer_id":46560388317346,"sku":"020226-Shield Arc-Panel Meters","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0335\/9824\/2861\/files\/img2026-02-02-12-36-43-930.jpg?v=1770057813","url":"https:\/\/cyclewarehouse.online\/products\/simpson-shield-arc-0-100-volts-amperes-panel-meter-lincoln-stable-arc-welders","provider":"cyclewarehouse.online","version":"1.0","type":"link"}
