4.4.5 recommended gas and Current
The following provide the recommended gas and current selection for common metals to obtain the best cutting results.
4.4.5.1 Carbon steel
1/8” (3.2mm) and Thinner
• 50 / 65 Amps, Air Plasma/Air Shield.
3/16 – 1/2 (4.8-12.7mm)
• 100 Amps, O2 Plasma/Air Shield.
• 100 Amps, Air Plasma/Air Shield is also good but there will be bottom dross on 1/2” (12.7mm) material.
NOTE: If using a 50 foot torch system, about 2-1/2 seconds will be required before the O2 reaches the cut.
5/8” (15.8mm) and Thicker
• 200 Amps, N2 Plasma/ Air Shield is best. Dross free cuts cannot be made on material thicker than 3/4” but dross is
removable.
• 200 Amp Air Plasma/Air shield is an economical second choice - a little more dross and a little rougher surface will
result.
4.4.5.2 Stainless Steel
1/8” (3.2mm) and Thinner
• 50 - 65 Amps, N2 Plasma/N2 Shield produces best surface but light dross on 1/8” material.
• 50 - 65 Amps, Air Plasma/Air Shield can produce dross free cuts but the surface is rough.
1/4 - 3/8” (3.2-9.6mm)
• 100 Amps, N2 Plasma/N2 Shield can produce little or no dross and good surface quality through 1/2” (12.7mm)
material.
1/2” (12.7mm) and Thicker
• 200 Amps, H-35 Plasma/Air Shield can produce nearly dross free cuts with excellent surface through 3/4” (19mm)
and more drossy but good surface through 1-1/2” (38mm).
• 200 Amps, N2 Plasma/Air Shield can produce dross free cuts up to 3/4” (19mm) with fair surface quality through 1”
(25.4mm) plate.
• 200 Amps, Air Plasma/Air Shield produces a slightly rougher cut surface but less dross on 1” (25.4mm) plate.
