HOW TO SELECT CUTTING TIPS AND OPERATING PARAMETERS FOR CHEM-O-LENE
TIP SELECTIONS: STEP 1
- Determine the manufacturer and model number of the cutting torches and/or cutting attachments being used.
- Determine the thicknesses of steel to be cut.
- It is also desirable to obtain the tip style, size and tip seating that is currently being used to serve as a cross reference during tip selection.
- Noting the manufacturer and model number of the cutting torch, select a tip manufacturer and tip designation for the torch. The National Torch Tip Catalog is an excellent reference for this selection step. We can provide this information to you.
- On Chart B below, select the tip size from the proper column for the thickness of steel to be cut.
OPERATING PARAMETERS: STEP 2
- Chart A below shows pressure regulator settings, fuel and oxygen flow ranges, and cutting speeds for the thickness of material being cut.
GENERAL
- For special applications, such as heating, gouging, weld washing, flame hardening, brazing, etc., obtain information in step 1 above and then call your Chem-O-Lene Gas representative for further instructions.
- Flowmeter panels are available to conduct in-depth test programs for comparing fuel gases.
