The red fuel gas hose connects to the hose barb that leads to the torch's red gas valve.
What size cutting torch hose do I need?
Hose Size: The I.D. (internal diameter) of hose used for most welding and cutting purposes ranges from 3/16-in. to 3/8-in (4.8 to 9.6 mm). When the length of hose required between regulator and torch is not more than 25 ft., 3/16- in. hose is adequate for all welding, and for most cutting and heating.
What type of hose is used for acetylene?
There are two grades of welding hose for acetylene. Grade R hose is the most popular and cheapest. Grade R is only for acetylene. The tube and cover are not flame or oil resistance.
What is the color coded of oxygen and acetylene hoses?
A blue color indicates the hose as suitable for use with oxygen, and a red hose is used for acetylene and other fuel gases.
What pressure should I set my cutting torch?
Recommended oxy/acetylene cutting tip pressures vary with size. If you have no manufacturer setting- information, and are cutting less than 1 ½” thick steel, set the acetylene regulator for 10 psig, and the oxygen regulator for 40 psig.
What does an acetylene hose nut have?
The fuel gas (acetylene) hose nut has an identifying groove cut into it. It also has a left-hand thread to prevent the accidental interchanging of oxygen and acetylene hoses.
Can you use propane in acetylene hose?
You WILL need to change your Acetylene Hose to a Propane Hose (including for Propylene). You will need to check the label on your Flash Arrestor, if it says “Fuel”, it's OK to use with Propane & Propylene. If it says “Acetylene” you will need to change it for a “Fuel” type.
What is the max pressure for acetylene?
Maximum pressure. Under no condition shall acetylene be generated, piped (except in approved cylinder manifolds) or utilized at a pressure in excess of 15 psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute).
Can I use acetylene hose for Argon?
Gas Welding Hose is used in the welding industry for transferring Acetylene, Argon, Oxygen, Propane gases under pressure.
What is green hose used for?
Green hose is used for carrying oxygen, and red hose is used for carrying acetylene. Bulk welding hoses are used to create custom hoses for welding applications. Cut these hoses to the desired length and add compatible hose fittings on the ends of the hoses to connect them to equipment.
What are red hoses used for?
In this case, the oxygen hose is invariably green, and the fuel hose is always red. The types of fuel used vary but the most commonly used are propane and acetylene. Natural gas, methylacetylene-propadiene (MAPP), and propylene are also used.
Can an oxygen hose be black?
(2) The generally recognized colors are red for acetylene and other fuel-gas hose, green for oxygen hose, and black for inert-gas and air hose.
What size are B fittings?

Fuel is left hand thread, and the nuts have hash marks across the corners to identify them. Oxygen fittings are right-hand thread and have no marks on the nuts.
What is the hottest cutting torch?
The hottest most-versatile gas, acetylene, is very easy to use for all purposes. Pre-heat time for cutting and gouging is relatively short because the flame temperature is between 5,600 and 5,800 F. However, this gas is the most expensive gas available and is not the most efficient for heating large areas.
What is the purpose of a cutting torch?
The purpose of a cutting torch is to cut through various sizes of metals. Most torch problems and complaints come from the torch tip and from the O-rings that seal the nuts. Over time, the ports inside the tip will develop blockage from metal particles and other debris and the O-rings will wear out. The torch can also malfunction ...
How to disconnect the top half of a torch from the bottom half?
