Sassafraspete,
That is exactly what dual shield means. You have a flux cored wire that you also use with a shielding gas. Not all flux cored wires use shielding gas (they splatter a lot). Set right, it gives a very nice deep penetrating splatter free weld.
Since I needed some time on projects in the welding class I was taking, it was a perfect opportunity to try out the machines in class. So I was able to use a .052 diameter wire (bigger than my machine at home could do). It gives a really nice profile welding bead.
I saw a grapple similar to this one when I first bought my tractor, the price was close to $2200! With a little bit of planning and rationalization I got a welder and materials to make my grapple for about the same price /forums/images/graemlins/smile.gif so, after it is all done, I still have the welder. /forums/images/graemlins/grin.gif
There are lots of things to build with the welder, tell your wife that she can take welding classes to learn how to use it. /forums/images/graemlins/smile.gif I have sure enjoyed learning to weld.
