Another 140 user here. H. Coe (and you acknowledge) makes great points. Btw
– I read ALL THE TIME how the 140 can’t mig 1/8 or larger. I have zero
issues using the mig process to 1/4″ (largest I’ve tried) as long as I
clean back to bright steel and bevel. I’ve etched, so I know for sure I’m
getting good pen. For gaps, I make sure my first pass burns into the base
metal, then subsequent passes burn into the weld. Haven’t had one fail
(yet).

No grinding? Cleaning the surface where you are welding? Brushing off the
welds to remove the flux before your next pass? I use a 140 also. I’d like
to have a bigger machine, but working with what I have and the get the best
possible welds, I clean every surface before a weld so I get the best
penetration and strongest welds that I can. I suppose filling a gap like
that is not a big deal if it is for art work, but if structural integrity
matters, maybe bolt in some plate before weld & fill.
Absolutely and great points. I wanted to demonstrate some backyard
techniques you could apply in a pinch. If this were going to get any kind
of non destructive test done to it or if it were to see any kind of
mechanical stresses where weld integrity and strength were crucial than
this would require a whole new approach. Many many things would be
different. I should have clarified a little better. Thanks for the
comments=)
