Hi As the R-tech has gone tits up I'm after a new welder. What would you like: new Parweld XTT 353P AC/DC or used Kemppi mastertig 3500W AC/DC? I have #20 water-cooled torch and homemade cooler already, so forget the Kemppi cooler for a moment. Also forget all the fancy features Parweld might have over Kemppi as the latter comes with minilog (without pulse) panel. What I am after is the hands-on knowledge of both.
