How do I choose a gas cut nozzle?

Four Steps to Proper Nozzle Selection

1. Choose One-Piece or Two-Piece Nozzle: Acetylene – one-piece nozzle always.
2. Choose Series: ANM, ANM-E, PNM, PNM-E, AFN nozzles.
3. Choose Preheat Capacity: Choice of nozzle depends on preheat capacity.
4. Choose Size: Select size recommended for thickness of steel to be cut.

What gauge should I set my cutting torch 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 the difference between an acetylene tip and a propane tip on a torch?

However, acetylene is much more expensive on a unit basis than propane. If you are using it for preheating- such as with a tiger torch- propane has some advantages.

What does the welding torch tip opening size determine?

Determine the metal thickness you want to cut. Select the tip size rated to cut that thickness or beyond. The tip size is based on the cutting oxygen gas orifice (using drill index sizes) – not always the pre-heat orifices. Recommended oxygen and fuel gas pressures are at the torch with gas flowing.

What determines the size tip to be used for cutting pipe?

diameter
A pipe’s diameter determines what size cutting tip is needed to cut that pipe. 8.

What is a cutting torch tip?

A torch with a specially designed tip is connected to a fuel tank, typically acetylene or one of three popular fuel alternatives, and mixes the fuel with oxygen in order to produce a high-temperature flame cone to cut through metals. …

What happens to acetylene above 15 psi?

Acetylene will not explode under low pressure at normal temperatures. However, it becomes unstable and spontaneously combustible when compressed to a pressure over 15 psi. Beyond 29.4 psi, it becomes self explosive, and a slight shock may cause it to explode even in the absence of air or oxygen.

Can you use a propane cutting tip with acetylene?

Propane can like acetylene be used for cutting. If you cut with acetylene, you normally put the tip of the inner flame cone on the metal (1mm from the plate surface). If you do the same with propane, you will be waiting for a long time.

Can I use an acetylene torch tip with propane?

If your working pressure is less than 15PSI you can still use the acetylene regulator because it is designed to be used under the same cylinder pressure as propane and propylene and provides maximum outlet pressure of 15PSI. The same nozzle can be used for both propane and propylene.

How do I choose a welding tip?

Select contact tips with a smooth surface to prevent wire snagging. Trim the MIG gun liner to the correct length so that the wire feeds through properly. Lower operating temperatures, if possible, to reduce electrical wear. Use shorter power cables when possible to gain smoother wire feeding.
