In addition to high-quality stainless steel cuts (See Stainless steel on page 215.), the N
2
and mixed-fuel gas HyDefinition consumables can be used to produce high quality cuts
on aluminum.

mixed-fuel gas
processes
OptiMix-equipped systems let operators use mixed-fuel gas processes for aluminum
cutting.
The OptiMix gas connect console has a 3-gas mixer that mixes H
2
, Ar, N
2
. The cutting
system chooses an optimized combination of 3 gases or 2 gases (H
2
, Ar) based on the
thickness of the metal to be cut.

water injection
processes
VWI processes use a low flow rate of water through the shield line (instead of shield gas).
A process that uses water as a shield fluid is sometimes called a “wet” process.
For aluminum, wet processes generally produce a smoother edge than “dry” processes.
Additionally, VWI lets operators get:
• A sharp top edge of the cut
• A smooth cut edge
• Excellent cut-edge angularity
