Well I am reading as much as I can, watching videos etc, but I still will never find an answer. I have a Static Arc MMA, so I have no prejudices against cheap welders, the MMA it's good, but only for 1mm and thicker. Does a cheap fluxcore good enough to tackle 0.7mm thin steel really exist? Some say you need a well known brand, some say you can try the Uptime or the Static Arc welder, some say you need gas otherwise you'll blow holes, some say you can try the Rohr or the Lidl (Parkside), some say you can do it with any machine as long as you go slowly using the stitch technique. Basically It would be helpful if there is some of you having a good experience about a cheap fluxcore for thin metal, something like 0.8 thin.
