Sometimes when I weld alluminum my welds have a frosty look to them . Mosty on an inside corner . The welds look fine just not shiney?

Some times it welds perfectly nice shiny beads . It is an older Miller ac dc machine with a high frequency adaptor . It has an adjustment for high frequency and I am not sure where this should be set . I do not do a lot of Tig welding so it could just be me . Thanks Bill

yea those old guy shakes are rough I hear. 

Ok seriuosly the older machines can not match the quality of weld you get from newer one at least not with me welding with  them.  I regret using a freiend new pulse welder a cpl years ago.Laid down perfect weld first shot with it.Now dying to get one.
