Orbitalum Power Supplies Orbitalum's OM series of compact orbital welding power supplies for automated GTAW offer a unique operating concept with a whole series of special technical features. When paired with an Orbitalum orbital weld head, the user has the most advanced, innovative and economical orbital welding system on the market. In addition to default welding parameters using the tube diameter, wall thickness, material, and welding gas, all ORBIMAT CA models include a FLOW FORCE function to reduce the pre-flow gas time when the weld heads are closed. Optionally the BUP control function with controllable, position-dependent tube internal pressure control is also available. The operating concept for this orbital welding power supply is quite different from the typical operating variants available on the market: The operator control features a color display with a single-knob operation used orginally in the automotive sector, and has become the preferred method used worldwide in the "information entertainment systems" in modern luxury vehicles. The main advantage of this style of control is that the gaze of the operator remains focused onscreen. Other technical refinements of the OM series include softkeys for essential, high-level and quick-action commands such as "Start/Stop". The integrated RTOS (Real Time Operating System) has the advantage that not even a direct, abrupt shutdown of the system will lead to any problems. This is particularly important in areas where power consistency is problematic. The RTOS always focuses on the steering and control of the welding process, which is ultimately crucial for the quality of the weld.
