General Notes - ESAB SCT-1500 Serie Instructions

GENERAL NOTES:

1. Pressures given are measured at the torch; therefore,
pressure drop through hose should be considered
when setting pressure at the regulator. Generally,
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.

 Use where high preheat intensity is desired.
 Consumption of MAPP or propane is approximately the same as FG-2.
*
Use soft-bristled brush (750F99) to clean preheat slots of internal nozzles.
 Heavy-duty sleeve (14Z96) available for use in place of 14Z77 sleeve.

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