OPERATING DATA, CLEANING DATA, AND PART NUMBERS
GENERAL NOTES:
1. Pressures given are measured at the torch; there-
fore, pressure drop through hose should be consid-
ered when setting pressure at the regulator. Gener-
ally, 1/4-in. hoses up to 25-ft. long are adequate for
cutting steel up to 4-in. thick. If longer hoses are
required and if cutting thicker steel, 3/8-in. hoses
should be used. If using low-pressure fuel gas,
3/8-in. fuel gas hose should be used for all cutting
operations.
NOTE: Primarily designed for use with FG-2 or MAPP. May be used with acetylene if heavy preheat is
desired.

If using LPNG injector (19417) in torch, it will operate with natural pressure less than 1/2 psig.
Use soft-bristled brush (750F99) to clean preheat slots of internal nozzles.

2. The table shows average values based on typical
conditions. The type and quality of steel, its surface
condition, the purity of the oxygen, etc. will always
have a bearing on the end results.
