I have a Astro powermig 110 made in italy I am using flux core wire with no gase do I need to reverse the polarity to use this type of wire. If so how do you do that on this mechine? or is it possible with this mechine?
you need to reverse the polarity yes. how it is done on that machine no idea but if it is designed for it there will be a link inside or two plugs to swap the cables over
