Tweco SLICE - Manual (Page 14)

Application Data
The following chart will help determine the best settings for a specific use. The chart
is a result of extensive laboratory testing of the SLICE Equipment to determine the
best cutting rates. Actual cutting results obtained in the field will vary due to
conditions and to the experience of the user. The way you use SLICE Equipment will
also cause your results to vary. For any use, you will need to adjust the settings. The
following chart is presented only as a guide.
How To Use Chart
The data chart is simple to use. First, best cutting was achieved by using an oxygen
pressure of 80 psi. Some uses may require higher or lower oxygen pressures.
Minimum oxygen pressure to use with the SLICE Torch is 40 psi.; maximum
pressure is 100 psi. Amperage over 200 amps does not improve cutting speed.
The chart is divided first by metal type and thickness.
A) 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" diameter flux-coated rods. Cutting
rates with 1/4" bare rods will be slightly less than the values listed in the chart.

Sample Selections
Cutting 3/8" (9.5 mm) aluminum with 1/4" fluxed rod: APPROX. cut/inch rod = 1.25
in. (3.2 cm) Amount of cut per rod = 19 usable inches (48.3 cm) of rod multiplied by
1.25 in. (3.2 cm) of cut/inch rod = 23.8 in. (60.5 cm) cut per rod used. APPROX.
cut/min. arc time = 38 inches (97 cm).
Cutting 1/4" (6.4 mm) carbon steel with 1/4" fluxed rod: APPROX. cut/inch rod = 1.5
in. (3.8 cm) Amount of cut per rod = 19 usable inches (48.3 cm) of rod multiplied by
1.5 in. (3.8 cm) of cut/inch rod = 28.5 in. (72.4 cm) cut per rod used. APPROX.
cut/min. arc time = 52 in. (132 cm).
