SLICE EXOTHERMIC CUTTING EQUIPMENT

SECTION 5: CUTTING DATA
The following chart helps determine the best settings for a specific use as a result of extensive
laboratory testing of the SLICE Equipment to determine the best cutting rates. Actual cutting results
obtained in the field vary due to conditions and experience of the user. Various usages of SLICE
Equipment return various results. Adjust the settings for any use. Use the following chart as a guide.
Oxygen pressure of 80 psi (551.6 kPa) achieves the best cutting. Some operations may require higher
or lower oxygen pressures - minimum 40 psi (275.8 kPa); maximum 100 psi (689.5 kPa). Amperage
over 200 amps does not improve cutting speed.
Find the right metal and thickness. For composites or unlisted metals, locate the listed type that most
resembles the material to be cut.
NOTE!
All these cutting values are based on 1/4" (6.4 mm) diameter flux-
coated rods. Cutting rates with 1/4" (6.4 mm) bare rods are slightly
less than the values listed in the chart.

SAMPLE SELECTIONS:
The approximate cut/inch rod x amount of cut per rod = cut per rod used
Data:
Cutting 3/8" (9.5 mm) aluminum with 1/4" (6.4 mm) fluxed rod
1.25" (3.2 cm) x 19" (48.3 cm) = 23.8" (60.5 cm). Approximate cut/min arc time = 38" (97 cm)
Data:
Cutting 1/4" (6.4 mm) carbon steel with 1/4" fluxed rod
1.5" (3.8 cm) x 19" (48.3 cm) = 28.5" (72.4 cm). Approximate cut/min arc time = 52" (132 cm)
