I understand dr clyde, I am on the other end of the fence, I think tig is highly over rated on the hobby type forum. Lets take the engineer here for example. He got no use for a mig but his living is made away with a highly specialized job and his cars while they are transport the nature of his work is closer to a hobby than a profession.
He is capable way beyond the avg guy asking the generic what machine question and has some training and some experience which I can see tend to taint for a better word the view of what most of this work is really like.
True with a lot of specialists, while a pipeliner might not think much of an AC/DC buzzer its probably a better pick for a guys first machine and is practical.
Same for every recent welding graduate, wants a Dialarc 250 like the one in school that was super, while this is technically correct and ok for some its really not needed, the 50A buzzer is really just as good unless a guy has some excavating equipment and really needs to run 5/32 lo hi.
Yes, that machine is a little better,,, or really bigger but it causes a lot of probems for the unleary also. Special; cords, heavy wire and service etc, not a problem for some but causes beginners all kinds of grief, hard to sell or move etc.
