Oxy Welding Tips

Single Flame

• When the oxygen and acetylene mix to produce a flame, the properties of the flame differ depending on the percentage of oxygen in the mixture, creating neutral, carbonizing or oxidizing flames. Neutral and carbonizing flames are used to weld metals and oxidizing flames are used to cut metal. A single flame tip is typically only able to produce a single type of flame, meaning they are used as either welding tips or cutting tips but not usually both. The tips come in a variety of sizes and cost about $10 each. They can be purchased from on-line retailers and welding supply or home supply stores.

Multiple Flame

• Unlike single flame tips that can corrode in the wrong type of flame, multiple flame tips can handle all three types of flame without degradation. This gives the tips and welder a wide range of abilities from a single tip. However, depending on the tip, there is sometimes a trade-off in precision as multiple flame tips don't always produce as precise a flame as a single flame tip. Multiple flame tips cost slightly more than a single flame tip, about $15 each, and can be purchased from on-line retailers and welding supply or home supply stores.

Specialty Tips

• Oxygen-acetylene welders aren't limited to cutting and welding steel. There are a number of specialty tips available that enable the equipment to heat large areas of metal or use specialized gases for brazing non-ferrous metals. C-flame tips spread the flame over a large area, creating an excellent heating tool. Twin flame heads produce two flames for a wider cutting or welding area. Finally, other specialized tips enable the welder to use other gases such as propane or even gasoline. These tips vary widely in cost from about $10 to $50 depending on the specific head. They can be purchased from on-line retailers and welding supply or home supply stores
