Direction of Cut
The plasma gas stream swirls as it leaves the torch to maintain a smooth column of gas. This swirl effect results in one
side of a cut being more square than the other. Viewed along the direction of travel, the right side of the cut is more square
than the left.

Swirl Effect on Side Characteristics Of Cut
To make a square - edged cut along an inside diameter of a circle, the torch should move counterclockwise around the circle.
To keep the square edge along an outside diameter cut, the torch should travel in a clockwise direction.
Underwater Cutting
Cutting on a water table either underwater or with the water touching the plate or with a water muffler system is not recom-
mended. If a water table is used the water level must be a minimum of 4 inches from the bottom of the plate. Failure to follow
this recommendation could result in poor cut quality and short consumable parts life.
Ohmic Height Sensing
Ohmic height sensing is not recommended with water shield. Water on the plate interferes electrically with the ohmic sens-
ing circuit.
