Thanks Lawrence, Already have the Phoenix. thinking about buying the Hi/Freq unit. Was hoping the Hi/Freq unit would convert DC to AC so I
could Tig weld some alum. Do you know of any such Hi/Freq unit that
does? If not, What would be the best bet, in your oppinion, the best
machine to GTAW alum. Already have a cobramatic hooked to a 450 power source to Mig alum. Just don't have an AC power source to Tig.
