Oxygen = High pressure tank (~2500psi)
Acetylene = "Low" pressure tank (~250psi)

Oxygen Tank Safety Feature = Burst Disk
Acetylene Tank Safety Feature = Fusible Plug

Fitting with notches are left handed thread

Gas fittings are tightened until snug, then given another ~1/4 turn

Acetylene is unstable above (~15psi-30psi) pressures and can explosively decompose

Your (cutting or welding) tip sizes will determine your WORKING (cutting or welding) pressures to set the regulators at

Always light with a flint lighter (not a compressed gas or BIC lighter)

Using a number 5 (UV) welding shade will get you by for most things oxy-fuel (darker shades are required for working on thicker materials)

Aim for a neutral flame before you begin any (cutting or welding), the pre-heat flames should be crisp and short

Flame types:
Carburizing - too much fuel gas in mixture
Neutral - balanced stoichiometrically
Oxidizing - too much oxygen gas in mixture

When lighting try to avoid backfire/back flash (it looks like you already have back flash arrestors installed after the regulators)

When regulator T-screws are LOOSE the regulator is closed

Open acetylene slowly at start, then only 1/4-1/2 of a turn to use

Open oxygen slowly at start, then open fully

Acetylene tanks contain a filler material (Acetone) that the (acetylene) gas dissolves into to stabilize it. If the tank has been laid on its side, allow time for the acetone to settle back down into the bottom of the tank before use otherwise acetone will come out of your tank and damage your regulator and hoses

A general rule of thumb is to avoid using more than 1/7 of an acetylene tank at a rip (or acetone may start to come out and damage regulator/hoses)


The above tells you nothing on welding/cutting techniques, or the differences between types of metals (etc.)


I will check this thread again later if you have additional questions

In my experience, the "best" bench will be simple at the start and grow organically as you use it.

Don't add too many drawers of extra shit you don't (or won't) need. As needs arise, add to the set-up in a logical fashion for your own work-flow.
