What are the oxygen and acetylene pressures when cutting?
The gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length …
What is the percentage of oxygen and acetylene in gas welding?
1 : 1
Due to the presence of unburnt carbon, its temperature is lower than the oxidizing or neutral flame. It does not produce any sound. Since nothing specific is stated in the question, by assuming neutral flame in case of gas welding, we can say that the proportion of acetylene and oxygen used in gas welding is 1 : 1.

How does oxygen and acetylene work?
Oxy-acetylene welding uses a high-heat, high-temperature flame that is produced by burning a fuel gas (most commonly acetylene) mixed with pure oxygen. The base material is melted with the filler rod using a flame from the combination of oxy fuel gas through the tip of the welding torch.
In which of these flames oxygen and acetylene are in same proportion?
neutral flame
3. In which of the following type of flame, oxygen is of same proportion with acetylene? Explanation: In neutral flame oxygen is in the same proportion with acetylene. Neutral welding flames are commonly used to weld: mild steel, stainless steel, cast iron, copper, aluminium, etc.
What is the temperature of an oxy acetylene flame?
about 3,200 deg.C.
Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg. C.
