Hi guys, trying to learn to weld some aluminum, have a millermatic 251 with 30a spool gun. Have watched a bunch of videos on this and am confused?
i see most telling me to use spray transfer and have a hiss sound instead of crackle sound. I can get that sound but it seams real hard not to burn back tips?
i seem to get a better weld with the other setting but got splatter. I'm not a welder so it is Greek to me. Is it just that I need more practice with it? A guy I know came by and herd the hiss and told me I don't want that. He is a certified welder
if so why do the videos say it??
thanks
