[AT] Welders

If you run a 7018 and try to stop and re-start before the rod is used up, the core will burn back past the flux.  If you "trim" the flux, it should start up ok.

I agree with others--definately spend the extra money for an AC/DC machine.

>DC will give you a much wider choice of rods to choose from.  Most of my welding is done with 6011 on the Buzz box, and 7018 with the DC Lincoln SA200.  They make 7018 that can be used with an AC machine, but with DC it works better for me.  It is so smooth.  It will be a little harder to "strike" an arc with DC, but no big deal.  If you can find a local welding supply, or know someone who would let you try DC, you will be impressed with how nice and strong the welds turn out.  I should mention the SA 200 is basically a DC generator, so the DC it generates is much nicer than the machines that just rectify the AC.
