Noise and smoke are greatly reduced with the water being close enough to the cutting face however the ohmic contact is never interrupted and cut quality is maintained.

Questions we received throughout the show were: Why do you have a water table Why are you not cutting under the water And why do some plasma systems have open-air tables with a fume extractor The question of whether to use open air vs.

Are you concerned about smoke and noise in your factory when cutting Do you require True Hole Cutting or fine cuts What is your target price point In addition, one would need to consider the different tradeoffs in cut depth and target quality.

True Hole processes are fast becoming the industry standard and shops need the capability of producing perfect cuts without secondary processing.

Cutting under water does not produce as clean a cut as open-air cutting.

When water touches the cut face or if the cut face is submerged in water, the electrical process creates small amounts of hydrogen through electrolysis.

This small amount of hydrogen immediately pops and nudges the arc, creating a rougher edge.

It is an electrical connection between the torch height control on a CNC cutting machine and the shield (front most part on a shielded plasma torch).

All HyPerformance plasma units, required for cutting mild steel thicker than, require ohmic sensing.

Ensure that your water level is at least 12 below the piece or use a down draft table to guarantee the ohmic contact isnt broken.

If this gas is not allowed to escape and safely evacuated, a buildup can cause an explosion.

Open air plasma cutting can each noise levels of up to 120 decibels, requiring ear protection for the operator and anyone near the machine.

By submerging the plate, you can effectively reduce the sound levels by 40 decibels, allowing continuous exposure without ear protection.

This arc can be so bright that looking directly at it can cause serious eye damage.

Operators and spectators require dark shades or a welding helmet, in conjunction with an arc shield.

However, submerging the torch head essentially eliminates the arc glare; one is only left with a glow under the water.

Cutting below water can capture almost 100 of the smoke and dust.

For example, when cutting with the water level about 12 below the bottom of the material to be cut, 98 of the smoke and dust are contained.

Reducing the heat helps prevent warping of the plate and allows safe handling of the part almost immediately after its been cut.

Depending on what you are cutting, the contents of your table may be classified as toxic and will require special drainage services.

Depending on your location, environmental procedures will vary and you should consult your local environmental authorities when considering plasma water disposal.

For our demonstrations, cutting materials 12 above water provides the optimal combination of benefits.
