Just a question about Tig machines ; I already have oxy-acetylene , a 225 AC/DC stick welder and a 200 Miller Mig machine , and want to add Tig but need another machine like a I need an extra hole in my head . I have a large 48 volt storage battery that's wired into my solar array and am tempted to use it as a DC source . Has anyone tried Tig off a DC source other than a Tig machine ? I'm determined to try this as I'm waiting on 55 parts deliveries , and it's either this or the dreaded home reno projects . I tried on 2 other occasions to get input from the Trifive.com members , but got nothing but smartass jokes and negativity from people that should know better namely 2 of their so-called "leaders" , RickL and NickP . I gave up and deleted the thread in disgust . I already have ONE asshole , and don't really need two more . Has anyone here tried this or am I just inviting more negativity and stupid comments ? I can tap this large battery storage across any combination of voltages from 0 - 48 vdc , and have a new 200 amp water-cooled Tig torch ordered ; I figure I'll pick up the argon gas when the Tig torch arrives . Anybody can throw money at a situation , but where's the satisfaction in that ? Any experimenters out there ? Be safe...Bob.
