Universal Arc Frequency Rectifier UAFR 250 AC/DC

Compact inverter rectifier for arc welding with microprocessor control indented for argon arc welding of heavily-alloyed steel, aluminum and other nonferrous metal with non consumable electrode (TIG/VIG) on the direct or alternate current and provides:noncontact arc firing at build-in oscillator; qualitative seam formation; smooth time regulation of arc current raising; crater welding; smooth regulation of alternant current pulse ratio (cleaning and penetration phase of welding cycle);the safe lowered voltage of idling; control of welding current with the help of digital indicator; developed protection from overheating, emissions of circuit voltage, short circuit of welding circuit.
