Oxy Acetylene Welding Basics

Oxy Acetylene Welding Basics

 

In order to produce welds that are pleasing to look at, like the first image, a great deal of practice mixed with patience is what it takes. Also, a complete understanding of how to setup and use the proper adjustments is essential.

To start with, you need to understand the difference between the oxygen tanks and the acetylene tanks. The oxygen tanks are designed to hold pressures in the 4,000 psi range and the acetylene tanks are designed to hold pressures of around 400 psi. They never come filled up completely from the welding supply store so don’t worry if you get a filled oxygen bottle with only 2,200 psi in it or an acetylene bottle with only 300 psi. That is just how it is but most importantly, do you see the vast difference between them? The oxygen holds way more pressure than the acetylene.

The way we control or work with the pressures in the tanks are through regulators (shown above). You will notice there are two gauges per regulator. The one on the left indicates working pressure and the one on the right tells us the tank pressure or how much we have left in the tank.

If you are about to weld some 1/8″ steel with a #2 torch tip, what are some working pressures that I would set my regulator with?

oxygen tanks has to be open all the way, and the acetylene tanks put it about 15 on the regulator.

Jermaine. That is not a working pressure. You are talking about just opening up the tanks and I’m asking what you would set your working pressure gauges to…For example, 40 psi, 5psi,,etc.

hello jim, are the welds in the first pic, on the motorcycle frame, done with Oxy-Acetylene ? either way, they are very pretty welds…

and what filler was used ? thanks

Yes they were done with Oxyfuel. Braze welding is what was done and brazing rod was the filler, which gives it that copper color.

wow, thanks jim…. i have tig welded with silicon bronze before, but never gotten any of my oxy fuel welds to look like those beads. i guess i would need to practice more..
thanks and take care….

Depends on the thickness of the material being cut
