Whats an inverter-based welding machine?
An inverter machine uses special power switching semiconductors that boost the frequency of the incoming power from 20,000 to 100,000 cycles per second. Because increasing frequency permits reducing the number of copper windings and mass of the iron core within the transformer, an inverter’s transformer can weigh about as much as a bowling ball. Q: How can I tell if an inverter-based machine is right for me? A: Inverters offer many advantages that can improve your operation, including lightweight portability, space savings and primary power flexibility. Inverters for production weigh 37 to 89 lb., where a conventional TIG/Stick machine weighs 389 lb. Inverters shrink floor space requirements, too; they can even be mounted on a wall. This advantage may let you add more arcs without expanding building size. Inverters also provide input power flexibility. Where conventional TIG machines only accept single-phase input power, Miller inverters feature Auto-Link™ or Auto-Line™ technology that
