My machine is only 180A max which means I can only use very thin wire for Al, (0.35-0.45"). It is very fragile. My machine has V groove rollers on the main feed which causes the wire to chip and this clogs the liner and small flakes of Al are nearly impossible to move once deposited. The thin wire also buckles and burns back easily adding an even bigger headache and the liner must be replaced far too regularly to make it worth while. Spool gun = short wire feed = no bending or flaking = happy welder.
