Latest Patents

Bergsrud holds a patent for his invention titled "Plasma Arc Collimator Design and Construction." This improved collimator features an annular holder member and an insert member. The insert member includes a tubular stem portion that ends in an integrally formed, radially extending face plate. When the stem portion is fitted into the central bore of the holder member with a predetermined clearance fit, a cooling water passage is created. This design is characterized by the absence of any welds between the holder member and the insert member, which would be exposed to conductive gases during the use of the plasma arc torch. Additionally, it offers a lesser resistance to cooling water flow compared to prior art collimator designs. Bergsrud's patent is a testament to his innovative approach to solving technical challenges in plasma arc technology.
