Underwater plasma cutting

Underwater plasma cutting is very much different from normal plasma cutting.Smoke elimination and decrease noise level led to underwater plasma cutting.High power has been used in an attempt to cut underwater.The danger to cutters are very high compared to normal plasma cutting.The high power goes up to 100 Amp for underwater plasma cutting.

The work piece in underwater plasma cutting immersed about 2-3 inches and the torch cut the work piece while immersed in the water.The noise and the arc glare reduce instantly while performing the cutting.Normally the operator cannot fully observed the plasma cutting works and the quality cut are reduced around 20 percent.
