Good news- We have unprecedented access to information.Bad news- There is too much information.
Frustration with large tip cutting torch operations is common. Tips burn up and results just aren’t what are expected.
Enter easy-to-use gas flow guides like those published by Victor. It only took two of us who knew what we were looking for about 30 minutes to find them today online. They are probably easier to find if you are one person with less presupposed knowledge…….. or not. You can also just drop by your local welding supply and pick them up.
Anyhow- check out the flow requirement for a #8 tip and you’ll see the oxygen flow needed for a type 303M, GPM, GPN, GPP is 450 to 500 scfh. Go to a Type 1-101, 3-101 (Oxy-Acetylene) and the oxygen flow requirement is 900-1050 scfh. Back in the day when your #4 tips system was fed by oxygen gas 16- packs everything was fine. The only problems were the weight, size and cost so you go to a liquid cylinder and all is fine. That is until a #8 tip is needed and no one ever mentioned that the maximum 8-hour flow rate from a 180 liter liquid cylinder is 350 scfh +/- depending on the manufacturer.
Result- A big powerful torch that is now starving for air which is kind of like a Ferarri with a wet air filter….. all show and no go.
Solution: Additional vaporization.
New Result: More air; More cut. Maybe even a speeding ticket….
