Tig dp 221Hpa AC-DC

Brand Name: STEL

Model: Tig dp 221Hpa AC-DC

Origin: Italy


New Generation of TIG

The Inverter Welding Power Source Tig dp 221H-221Hpa AC/DC is managed by a new and innovative microprocessor, that presents to the operator all the features and benefits required to perform very high quality welding of aluminums, stainless steels and many other materials.

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.
