Sorry I typed wrong name. It was Rudy that met up with me helped me out with the part.

Yes. The pinhole is caused by the erosion of the line material by the
fuel as it makes the turn in the bend. High pressure fluids that are
moved by a piston type of pump seem to cause this more than fluids ran
by rotary pumps. Unfortunately unless you own an ultrasound or x ray
machine you cannot measure the amount of wear in the corners.

For welding body panels, my preferred welder is a Lincoln SP-135
with MIG. Hobart has a similar rig with the only real difference
being one has plastic wire motor parts and the other has similar
parts made of pot metal. (I forget which is which.)
I also own a 225 amp Lincoln "Buzz Box" (AC Welder) and I can
attest that while I can stick things together (more or less) with
this, I truly became a weldor (note the correct terminology) when
I purchased the SP-135. You just can't see the puddle with an AC
welder since the AC rods have so much shielding flash.
I preferred the Lincoln brand since my local welding store
handles Lincoln and parts and supplies were readily available.
If you persist and buy flux cored wire for your welder, you will
get better welding results using gas even with the flux core
wire. There is something about the flow of gas which flattens
and cools the weld and add materially to your welding skill. .
You'll know you're doing your best welding when you get that "fat
frying in the frypan" sort of sound with a MIG. And for welding
the real thin stuff with the finger trigger you can go
spot/spot/spot/spot and guarantee you won't have a burn thru.
And if you inadvertently do, you can go spot/spot/spot/spot and
simply close it in.
I worked at a local farm and they have the Lincoln SP-125 which
is an older version of the SP-135. Functionally (and probably
internally) it is the same machine and these machines are readily
available used on Craigslist or the WantAdvertiser at
considerable savings.
I would tend to steer clear of Cambell-Hausfield, Century,
Chicago Electric or any other of those aluminum wound transformer
machines.
Happy welding,
Joe

So is the hole on the inside of the bend ... fatigue?
Or is it on the outside... erosion?
Mark
Even steam erodes pipes on bends!

Only catch with oxy/acetlyene is heat/warping the panels.
You can surround the area with a wet rag and quickly wipe.
MIG will let you spot, spot, spot and not build up heat. I
never tried flux core MIG. Since the standard is with gas then
there's usually a reason. ;-) Most MIG is with CO2 AFIK. TIG
tends to use argon. Seems I've heard of some difference in
why you'd use argon with a mig. Maybe it had to do with
aluminum or such. I just don't remember the reasoning. :-P

I felt like you that oxy/acetlyene introduced too much heat and just maybe this was an older method, while still
used, not as good as current tech.
I have used mig with fllux core and it was messy and weak.
I have seen many use mig with co2 gas with good results on metal fencing and wondered about the gas
type as some used argon over co2 and preferred it
they both produce a sheilded weld so is argon hotter

MIG on steel can use CO2 shielding gas (runs hotter and not quite as clean, but
inexpensive), or Argon (runs coolest and is most expensive) or a mix of 75% CO2 and 25%
Argon for a good compromise. For sheet metal, the trick is not burning through, so you
need the smallest gauge wire (like 0.020) and some sort of shielding gas, either the mix
or pure Argon would work the best as they are cooler than pure CO2. Flux core tends to be
even hotter than solid wire MIG, I think that is why they use flux core on the lower amp
units, helps them weld thicker material (plus is is a less complex setup = lower cost
welder).
