The flame produced is larger and bushier, providing full crucible coverage and reducing the oxidation risk associated with pure oxygen\/gas melts. While a compressed air flame burns at a lower temperature than a pure oxygen flame, it delivers more than sufficient heat for casting applications. This approach is widely used in European jewelry and metalsmithing workshops.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFor best results, use with propane.\u003c\/strong\u003e Natural gas does not burn as hot and will most likely require a natural gas booster to achieve adequate temperatures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant warnings:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDo \u003cstrong\u003enot\u003c\/strong\u003e use with oxygen — doing so will damage the tip.\u003c\/li\u003e\n\u003cli\u003eDo \u003cstrong\u003enot\u003c\/strong\u003e use with Acetylene or Hydrogen gas.\u003c\/li\u003e\n\u003cli\u003eDo \u003cstrong\u003enot\u003c\/strong\u003e use with the Swiss Made G-Torch II — this head is compatible with the Swiss Torch Body 114.109 only.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCompressed air and gas casting head — no oxygen required\u003c\/li\u003e\n\u003cli\u003eProduces a large, bushy flame for full crucible coverage\u003c\/li\u003e\n\u003cli\u003eReduces oxidation risk compared to pure oxygen\/gas melts\u003c\/li\u003e\n\u003cli\u003eStamped D-2bar (Druckluft = compressed air in German)\u003c\/li\u003e\n\u003cli\u003eWidely adopted casting torch configuration in European metalsmithing\u003c\/li\u003e\n\u003cli\u003eHead-only component for use with Swiss Torch Body 114.109\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel Number\u003c\/th\u003e\n\u003ctd\u003e246.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Torch Body\u003c\/th\u003e\n\u003ctd\u003eSwiss Torch Body 114.109\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGas Type\u003c\/th\u003e\n\u003ctd\u003eCompressed air and gas (propane recommended)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Air Pressure\u003c\/th\u003e\n\u003ctd\u003e2 Bar (30 PSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Temperature (Propane)\u003c\/th\u003e\n\u003ctd\u003e1875–1925°C (3400–3490°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOxygen Use\u003c\/th\u003e\n\u003ctd\u003eNot permitted — will damage tip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProhibited Gases\u003c\/th\u003e\n\u003ctd\u003eAcetylene, Hydrogen, Oxygen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncompatible Torch\u003c\/th\u003e\n\u003ctd\u003eSwiss Made G-Torch II\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Swiss Torch","offers":[{"title":"Default Title","offer_id":43581492363478,"sku":"114.114","price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/swiss-torch-compressed-air-casting-head-not-for-use-with-oxy-otto-frei.jpg?v=1719957550","url":"https:\/\/www.ottofrei.com\/products\/swiss-torch-compressed-air-casting-head-246-1","provider":"Otto Frei","version":"1.0","type":"link"}
