What pressure should oxygen and acetylene be set at for welding?

What pressure should oxygen and acetylene be set at for welding?

In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size.

What are the oxygen pressures for cutting and welding?

The oxygen pressure ranges between 0.7 to 2.8 bar (10 to 40 psi), depending on the size of the torch tip. A jet of relatively high-pressure oxygen produces the suction necessary to draw the fuel gas into the mixing head. The welding tips may or may not have separate injectors in the tip.

What are the parameters in flame cutting?

Proper cutting oxygen pressure selection. Proper preheat (a function of the cutting tip and the operator) this includes quantity of preheat as well as ratio of Oxygen to the fuel gas. Proper cutting speed. Proper tip to work.

What pressure should oxygen and fuel be set at for 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 ratio of oxygen to acetylene?

Natural Gas

Table : Fuel Gas Characteristics
Fuel Gas Maximum Flame Temperature °C Oxygen to fuel gas Ratio (vol)
Acetylene 3,160 1.2:1
Propane 2,828 4.3:1
MAPP 2,976 3.3:1

What is the pressure of oxygen cylinder?

2000 psi
Oxygen cylinders are prescribed as regular general practice items with further prescriptions needed for replacement cylinders. The oxygen is stored in the cylinders at 2000 psi with a pressure regulator that allows 50 psi to the patient.

Which flame is used for oxy acetylene cutting?

Neutral Oxy Acetylene Flame
A Neutral Oxy Acetylene Flame is used for Welding, Brazing and Silver Soldering most metals and is therefore the most common type of flame to use. A Neutral Flame is also used for Oxy Acetylene Cutting.

What are the parameters in flame cutting on metals?

The ideal parameter level for Surface Roughness are 6.0 Bar (Gas Pressure), 150 A (Current), 400 mm/min (Cutting Speed) and 2 mm (Arc Gap).

What should I set my oxy acetylene gauges to?

The recommended setting is for the fuel gas regulator to be set at 10 psig and the oxygen regulator at 45 psig. This recommendation applies when cutting less than 1.5 inch steel with the use of propane, propylene or natural gas.

What is oxy acetylene welding?

Oxy Acetylene weldingis a welding process manually, in which the surfaces to be joined, which is warming to melt by a gas flame Oxyacetylene with or without filler metal, where the connection process without emphasis. In addition to the purposes of welding (connecting), gas welding can also be used as preheating, brazing, cutting, and hard facing.

What is oxy-fuel welding?

Surfacing by oxy-fuel welding is a procedure by which weld metal is deposited on a metal surface to produce certain de- sired properties or to restore dimensions. It may be per- formed on new parts to restore them to usable condition.

How do you set up an oxy-acetylene welder?

Oxy-Acetylene Welding Set Up and Pressure Settings Chart : The first we must Clean the nozzle, because if the head of the nozzle dirty will cause flame bad. Open Regulator Oxygen and Acetylene, set until the pressure matching with what do you want or for acetylene 5 to 7 psi and Oxygen 7 to 10 psi.

How do you measure excess fuel in welding?

For ordinary carbon steel welding, excess fuel is measured by the feather of unburned fuel and the end of the inner cone; this should be 1½ times the length of the inner cone.
