Differences between them spec wise...
TecArc offers a pulsed TIG to 300Hz which is more useful than the Rtechs max of 25Hz. As i said a high frequency pulse constricts the arc improving focus and stability. Pulsed DC TIG is most useful on thin stuff, especially heat sensitive materials like stainless. The Rtech offers adjustable AC frequency, TecArc doesn't appear to. Higher AC frequencies again constrict the arc improving focus. Most useful for say, fillet welds on thin ally so swings and roundabouts in that regard between 'em
TecArc is a little cheaper, both are based on/reworked cheapnese kit. Can't put one ahead of the other as while i've used similar (various different badges) kit i've never owned one. Mates ones that i've welded with were OK to use. Customer service for either should be good. A search of the forum will find several fairly recent posts that suggest faulty machines straight out of the box are not a thing of the past...
