welding anodized aluminum

How important is having a high frequency tig welder? The lincoln precision tig 225 welder was recommended to me. But this welder has 60 HZ output plus some other features. The main use for this welder is to repair anodized aluminum entrance doors. Would this welder do the job? Or should I be looking at a different machine?

--------------------------------------------

High freq is necessary.

The lincoln 225 might do the job fine, but I dont think it is the absolute best tig welder for the job.

I like the newer inverters with adjustable ac freq and ac balance.

But depending on the skill of the welder and willingness to learn and adapt to the newer controls, it might not make any difference.
