Soitaab’s Plasma Grate Cutting System, uses a patented HotWire process to cut interrupted surfaces like grating at high speeds, both efficiently and with high quality. The concept is indirect plasma cutting 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 torch is thus fooled into thinking there is a continuous cutting surface and the grate beneath is cut in the process.
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.
