The required amperage for an aluminum spool gun depends on the thickness of the aluminum being welded. Generally, welding aluminum with a spool gun requires about 1 amp per 0.001 inch of material thickness, so welding 1/8 inch (0.125") aluminum would require around 125 amps. Always check your welder and spool gun specifications for recommended amperage ranges.
