Opening the valves
by: Shahidan

I was told to open the acetylene valve no more than half a turn.This I followed.
But I was told to open the oxygen valve fully to avoid damaging the valve sitting. And you said not to.Which is right?

Thank you.

If you blew up your torch handle, your torch was screwed up. Arrestors would not have prevented this from happening, but I still use them so I don't burn the hoses and have the flame get to the tanks.

safety first

My rule of thumb is to never turn the acetylene bottle valve open more than 1/4 turn! I also use flashback arrestors on both ends of the hoses.

When using Oxy acetlene equipment the proper way to open the bottles oxygen fully open for unbrestricted flow acetylene 1/4 turn open. In the case of a flashback shutb the oxygen of first other wise when shutting down the acerylene is shut of first. You can have flash arrestors on the end of the torch and on the gauges,double esttors never hurt.

Bubble testing
by: Rod Hancock (aka Welding Rod)

Good safety comment!

Another often overlooked safety tip is to always bubble test connections when changing tanks.

Many welding gases are inert and relatively harmless unless you are in a confines space; then they can kill you. Not trying to scare anyone off, just be aware of the hazards.

At the very least it is a waste of gas; in the case of gases like propane, acetylene or MAPP gas you may be looking at a potential fire or explosion.

Back in the stoneage when I was fresh out of welding school I ended up working at a Ministry of Highways position way up in northern BC as my first professional welding job. Kept notes for the nine months I was there, possible book someday.

To make a long story short the old timers up there had a few good laughs at my expense- the rookie bubble testing tanks!

It was all very funny for them until the day an acetylene tank valve caught on fire..they were believers after that!
