LAC welders

[millertyme]

Eric,
If you think that flux cored wire is good, then you will say that solid
core for is grrrrrreat.
Like you mentioned, no chipping if running gas.  Another buddy of mine
is a professional welder, and he recommends that CO2 or argo-mix (mix of
argon, co2, and sometimes helium) is best for mild steel.  I rum pure
CO2, and my buddy runs mig-mix (75% argon, 25% co2).  The only
difference I see is that his welds are smoother.  The CO2 seems to run
hotter, so my welds are deeper, but require more grinding to make them
presentable to the critics.  Either way, IMO, gas is the way to go.
Just to be able to weld and not need a chipping hammer, is worth the $$.
The solid core we both use is .023 dia.  He is also using .030 stainless
316.

All I have is gas welders so sadly I would not know.  I actually usually

use the TIG for stainless, but I recently got wire for the MIG because 
it is faster.  Having to sort out gas blends can be annoying.  I 
generally have pure argon, but I think we mild steel it is not as idea 
(and more expensive)  than some of the blends.

I had not thought of that.  I would be concerned anyway with MIG due to 
the lack of high frequency start to clear the oxides.

Have you used the solid core for mild steel?  How does it work?  I guess

you have flux you have to chip off like with a stick?
