A Quick Question on TIG Welding

Sounds like a combo plasma cutter?
This is exactly what it is i mainly bought it as a plasma cutter as my mig is only about 2 years old and is a good brand for australia where as this plasma cutter is chinese and only cost $250 so if it does not work well as a tig or stick welder there is no problem as i also have a brand name stick welder that i have had since about 1983 and has had very little work, thanks for the info, i also need to get some straight argon so might be a while before i set up for tig,as i say i have never tig welded before so thought i might try it once i get this machine set up with all the bits it did not come with
