Precision Aluminum and Stainless Steel

		Thermal Dynamics systems use the Water Mist Secondary process to achieve high precision cut quality on aluminum and stainless steel.   This unique cutting process uses nitrogen plasma and water as a shield. The result is the best cut quality possible on stainless and aluminum, at much lower cost per foot than other cutting processes. Stainless Steel and Aluminum cut with the WMS® process are dross free and ready to weld.

The WMS® process uses nitrogen as a plasma gas and water as the shield. The water in the shield stream is divided into its principal components during the cutting process (hydrogen and oxygen). The hydrogen creates a reduced atmosphere in the cut zone, isolating it from contaminants. The result is a clean, dross-free and oxide- free cut surface that is ready to weld. Most of the water used in the cut process is evaporated.

In the WMS^® process, tap water is used instead of a shield gas.  The water is vaporized as it passes through the torch head and a portion of the molecules separate onto hydrogen and oxygen.  This vapor protects the cut surface from ambient air contamination and eliminates contamination in the cut surface.

Cutting with the N2/WMS process is economically efficient and produces genuine precision cut quality over a broad range of non-ferrous applications. 

Considerations:

• Water supply should be at least 55 psi.
• Hard water will leave mineral deposits, just as it does in sinks and faucets.  A standard water softening filter will prevent mineral deposits that can interfere with water flow in the torch passages.
• Ohmic sensing to establish initial torch height is ineffective when water is present.  The ohmic clip should be removed from the torch for N2/WMS cutting.  The ohmic sensing system will sense the level of any water on the plate rather than the true position of the plate.
