Hello all new to site,have a question regarding wire feed speed to burn off ratio on aluminum . Is ratio same for steel/aluminum ? I've had a miller matic 200 with a spool matic 30a for years and have never gotten it dialed in right
With aluminum? I set machine to parameters inside cover using 4043 wire .047 diameter . When I set machine for these
Parameters on say 1/4 " I burn right thru on arc strike or travel rate rediculous ? If I turn voltage way down arc gets better?
And yes I have polarity right. I know I need to spend more time with the machine wondering if anyone has any suggestions?
Thanks Rob
