something portable. Ok I no its a Miller forum and I am a Miller owner but I'm curious about the HTP invertig 221 verses a machine like a dynasty 200.ive done a little research and found nothing bad at all about the htp.Just wanting some honest opinions from people with some experience on them or someone with knowledge about them. You guys enlighten me I'm about to buy one I've only ever tiged AC on Lincoln precision tig welders. I'm wanting something portable.
