Hi Frank,
I've been considering a MIG welder too, and have been gathering info for a
while. What I've learned is similar to the other response you got already: flux
core is generally not as neat as gas shielded welding. Flux core is primarily
intended for outdoor use, when a breeze will blow away the gas. But, it will
tend to spatter more. Most of the time I plan to use gas rather than flux core.
It is nice to have a choice, though.
Yes, the high voltage models are more capable in some respects, but how often
will you really need to weld over 1/4" thick materials? Many 230V models only
allow 5/16 material, anyway. 220/230V models often do have a higher duty
cycle rating. You are lucky to have a 220/230V outlet available. But, how often
is
that the case? If you ever take the welder somewhere else to do a small job,
will 220/230V be likely to be available? Also, it's possible to "split" a
110/115V line off a 220/230V receptacle. I've got a short, homemade splitter I
used many years ago on construction sites, but I don't recall how I put it
together.
I'm looking at the Hobart line of 115V units, probably the Handler 140. (The
Handler 180 is 22/230V) These are made by Miller Electric, I believe, which is
a well respected line, but generally more expensive. Asking around, I've
heard a lot of good reports on Hobart models. More info at
www.hobartwelders.com ,
especially check out "Welding 101". There is also a lot of info at
www.millerwelds.com
Have you done other types of welding? I use an oxy/acetylene outfit a lot.
And, I've used a stick welder occasionally. I understand MIG is easier to use
than gas. The auto feed has got to be a big convenience, compared to stick
welding. And, it's a lot faster than TIG, although the latter can handle a
wider
variety of materials and makes super neat welds.
One key consideration is "duty cycle". This varies depending upon the power
setting, may be only 20 or 30% at top power setting with some units. That means
that you can weld for 2 or 3 minutes out of every ten, for all practical
purposes.
Hope Santa brings you what you want!

Hi guys
well as Christmas approaches IM looking for my present. And the one thing
that IM thinking of asking Santa for is a MIG welder.
