I'm hiring one at the moment, but I've had about 2 hours practice, from never holding a welding torch so far. So I'm not really qualified enough to give an informed appraisal yet IMO.
As I've not welded with anything else, I've got nothing to compare it against.
One thing I do know, is that after searching the web for reviews, I found hardly any. So it appears not to be a well known company. Which doesn't help when looking for an unbiased opinion, or critical reviews.
Sorry, that doesn't really help you in relation to your original question. But if you ave any specific questions I'm happy to answer them.
Parweld is a brand of machines manufactured by Nurkay Kilmak Makina, the same company that made the Fantom 165 inverter welder that I recently repaired. Parweld UK is just their distributor arm.
