Marine grade aluminum 3/8 butt 2,3,&4-G H-plate weld test .035 , interpass temp ? , Also settings , volt & wire speed ? Using Miller saw or , " suicide saw " ,4 1/2" on electric grinder used between passes , do I need to be aware of square cut , should I try to feather a smooth groove like mild steel flux cored? Any more tips ?
