Typical systems feature a minimum\u00a0150A power supply and the higher the current employed, the faster the cutting speed which can be achieved.<\/p>\n<p>Our hardfaced plates may be cut from either side, but to accommodate the natural bevel created by this process it is recommended that cutting takes place from the hardface side. Cutting speed should be adjusted to minimise the build-up of slag on the underside of the hardfaced plate.<\/p>\n<p>High definition plasma arc cutting is recommended where close tolerances are required.<\/p>\n<h2><strong>Water jet cutting<\/strong><\/h2>\n<p>In this process a very high pressured water jet is used, usually mixed with a fine abrasive which enables materials to be cut cleanly and to close tolerances. Plate thickness up to 40mm can be cut.<\/p>\n<h2><strong>Air arc gouging<\/strong><\/h2>\n<p>A compressed air supply and a conventional constant current DC welding power supply, with a minimum OCV of 60V (80V recommended) is required for air arc gouging.
