RECOMMENDED GAS AND CURRENT

The following provide the recommended gas and cur-
rent selection for common metals to obtain the best
cutting results.
CARBON STEEL
1/8" (3.2mm)
and Thinner
3/16 - 1/2
(4.8-12.7mm)
1/2" - 2"
(12.7mm - 50mm) 150 Amps, Plasma/Air
STAINLESS STEEL
1/4 - 3/8"
(3.2-9.6mm)
50 / 65 Amps, Air
Plasma/Air Shield.
100 Amps, Plasma/Air
Shield. 100 Amps, Air
Plasma/Air Shield is also
good but there will be
bottom dross on
1/2" (12.7mm) material.
100 Amps, N Plasma/N

can produce little or no dross and
good surface quality through 1/
2" (12.7mm) material.
100 Amps, Air Plasma/Air Shield
is as good on bottom dross but
produces a rougher cut surface.
STAINLESS STEEL
1/8" (3.2mm)
and Thinner
ALUMINUM
1/4" (6.4mm)
Shield and Thinner

OPERATION
50 - 65 Amps, N Plasma/N

Shield produces best surface
but light dross on 1/8" mate-
rial.
50 - 65 Amps, Air Plasma/Air
Shield can produce dross free
cuts but the surface is rough.
50/65 Amps, N Plasma/N
2
Shield usually produces fairly
smooth,dross free cuts.
50/65 Amps, Air Plasma/Air
Shield produces much
rougher cut surfaces.
