Soitaab’s Plasma Grate Cutting System, cuts interrupted surfaces like steel or aluminum

August 25, 2017 -Soitaab’s Plasma Grate Cutting System, cuts interrupted surfaces like steel or aluminum grating at high speeds, both efficiently and with high quality results.

When trying to cut an interrupted surface like a steel grate with a plasma torch the arc jumps from surface to surface as it passes over the bars of the grate. The cuts are haphazard and there is no predicting where the arc will land on the next available surface.

This innovative process uses the patented Kjellberg Hotwire indirect plasma cutting system where a welding wire is automatically fed underneath the torch. This wire acts as the anode, completing the electrical circuit without a direct connection to the work piece. The wire simulates a continuous surface under the torch and the grate beneath is cut as if it were a flat plate. There is no slow-down of the plasma torch, no-pre-heating of the surface, and no loss of the plasma arc as the torch moves across the interrupted grate surface.

The results are a very clean, high quality, accurate cut with little to no re-work on the surface. The speeds approach typical plasma cutting speeds and are 5-10 times faster than other methods currently in use.

When not in use, the grate cutting attachment can be easily removed for standard flat plate cutting.
