Hi I just joined this site after alot of searching . I need advice on what welder to buy . All I have is single phase it for around the farm it will be used alot. Mostly 2.5 and 3.2 rods and 1.6 for excaust pipe. Iv 3 welders I'm thinking of ewm fronius and Kemppi I can't deside. Are these as reliable as people say
