    The Powermax45 is a highly portable, 45-amp, handheld and mechanized plasma cutting system appropriate for a wide range of applications. The Powermax45 uses air or nitrogen to cut electrically conductive metals, such as mild or stainless steel or aluminum. With it, you can cut thicknesses up to 25.4 mm (1 inch) and pierce thicknesses up to 9.5 mm (3/8 inch).

  • Page 28: Generator Recommendations

    Prepare the gas supply The gas supply for the Powermax45 can be shop-compressed or cylinder-compressed. A high-pressure regulator must be used on either type of supply and must be capable of delivering gas to the filter on the power supply at 170 l/min at 6.2 bar (360 scfh at 90 psi).

  • Page 29: Connect The Gas Supply

    When site conditions introduce moisture, oil, or other contaminants into the gas line, use a three-stage coalescing filtration system, such as the Eliminizer filter kit (128647) available from Hypertherm distributors. A three-stage filtering system works as shown below to clean contaminants from the gas supply.
