Really, really good piece of kit this, after using Cebora transformer Tigs for the last 15 years, I finally bit the bullet and entered the inverter age. Why oh why did I not do it before, this is a really good set, everything you need was supplied along with an instruction book that tells you what you need to know rather than a million things you don't. Very impressed with the quality of the product and the customer service is 2nd to none. Many thanks
