Tig µP 273H DC

Brand Name: STEL

Model: Tig µp 273H DC

Origin: Italy


New generation of TIG.

The INVERTER technology of the Welding Power Source TIG μP 273H DC gives this welding machine professional calibre and welding quality. The advanced technology of its powerful microprocessor results in a perfect arc ignition every time. The availability of 60 programmable memories allows for the construction and recall of all parameters selected.

V.R.D. means: VOLTAGE REDUCTION DEVICE which is the reduction of the OCV(open circuit voltage) at a safety level below 25 V, in order to avoid Electrical Shocks. When the V.R.D. is activated the led showing the mode of welding will pulse.
