In general for practical shape cutting the quanties required are Natural Gas 10-20 CFH and 18-36 CFH Oxygen, and Propane 5-10 CFH and 23-45CFH Oxygen. By adding oxygen gas, torch outfits can produce flame temperatures of 5,620 degrees. If the gas has out from nozzle you can use lighter and light the torch. Oxy-Fuel, ©2021 ESAB. It is, therefore, necessary that proper safety and operating procedures are understood prior to using such apparatus. Genuine Victor® replacement cutting tips are individually flame-tested to ensure maximum quality and performance. The flame temperature is controlled by adjusting the O/F Ratio. It’s very important how you set these things. >> For a pierce start a very high flowrate (at the correct O/F ratio) is required followed by a significantly lower flowrate (again at the right O/F ratio) for the continuing cutting operation. Victor® offers a complete range of cutting tips for oxy/acetylene and oxy/fuel cutting. /ColorSpace << SOP 15 – Oxy Acetylene – Cutting & Welding DO NOT proceed in this operation unless appropriately instructed in its safe use and operation and permission to operate has been given. endobj An oxy-propylene torch is just quicker. /Author (2) Multiply that number by 7 and that is the minimum size tank you need to use.

MFA HEATING NOZZLES #10 tip size 12-15 PSI Acetylene 30-40 PSI Oxygen 40-100 CFH Acetylene Flow 44-110 CFH Oxygen Flow #12 & #15 are the two largest sizes in MFA (Multi Flame Acetylene) The #15 also uses 12-15 PSI Acetylene, but needs 50-60 PSI Oxygen. Oxy-Acetylene & Oxy-Hydrogen Application Torch Series Nozzle Type Available Sizes Illustration General purpose welding & heating. There are also some mixtures of natural gas or propane with some additive that claims to make them hotter. Stand away from front of regulator; Separately and slowly open the oxygen and acetylene cylinder valves; Adjust regulator p/a screws to tip pressure settings; Open/close torch valves separately and fine tune pressure settings on regulators; Depress cutting lever and adjust pressure if necessary An oxy-acetylene torch can get the metal so malleable that it melts, which is usually the last thing you want, except in the very special circumstances we’ll talk about now. /GSa 3 0 R /XObject << Use a cylinder cart if available but if not, ensure that they are properly fastened or chained to a sturdy object, post, beam, or wall. Acetylene discharged into air (or an oxygen/acetylene torch) at pressures greater than 15 PSIG may cause the gas molecules to disassociate, resulting in free hydrogen gas, which is highly explosive. The actual recommended quantity (CFH) of fuel and Oxygen varies with the tip manufacturer and tip purpose. endobj /URI (http://my.manualslist.ru/list.php?q=Victor Oxy Acetylene Torch Settings) Босна и Херцеговина (Bosnia and Herzegovina), Al-‘Arabiyyah as Sa‘ūdiyyah المملكة العربية السعودية (Saudi Arabia), Al-’Imārat Al-‘Arabiyyah Al-Muttaḥidah الإمارات العربيّة المتّحدة (United Arab Emirates), Israʼiyl إسرائيل, Yisra'el ישראל (Israel), Al-maɣréb المغرب, Amerruk / Elmeɣrib (Morocco), Muritan / Agawec, Mūrītānyā موريتانيا (Mauritania), République Centrafricaine, Ködörösêse tî Bêafrîka (Central African Republic), Mǎláixīyà 马来西亚, Malaysia, மலேசியா (Malaysia).
