I am looking into getting the Spectrum 375 Xtreme and had a few questions for all of you. I have owned a couple miller welders in the past and have been very satisfied with the performance. I know they are top of the line welders and I want to stay with Miller for my plasma cutter as well. Would you guys recommend this welder? (Most of my stuff is 1/4" and below, however occasionally i do some 3/8 and 1/2 work.) Will this plasma cutter be enough? Also i noticed that in the specs it says rated at... quality.... and severe.... Each phrase is followed by a thickness in inches. I know they are referring to metal thickness but which one do i go by? Please let me know what all of you think. Thanks.

Btw I am just a home hobbiest.
