I weld for a living. Very well, in fact. I've seen your welds, Evan.
You're not in a good position to talk like this.
Constructive criticism for abba:
Too much wire speed!
Here's the wire/amperage adjustment theory:
Always set up on scrap first.
Turn down the wirespeed until the crackling dies down, but not far
enough that the wire balls up before reaching the weld.
The amperage can be thought of as "heat", there needs to be enough to
melt the parent material appropriately, and the wire as well. That's
why amperage will vary far more than wirespeed for varying metal
thicknesses, the thicker metal acts as a heat sink. Joints affect the
adjustments, as well. Welding into a corner, the arc is available to a
much greater surface of the parent metal, and the wirespeed (and
possibly the amperage, slightly) needs to be higher to carry the weld
down into that corner. On an outside corner, the arc is concentrated on
a smaller area, and the amperage needs to be turned down to prevent
burnthrough due to the limited metal area exposed to the arc.
It takes practice, be patient, and you'll get a sense for it.
-Keep the weld joint flat during welding, if you can.
-When welding steel, the welding gun should be aimed back, 10-30
degrees, across the weld, whether you're using gas shield, flux core,
or even tig. The weld needs to be shielded while it cools.
-While you're using the flux welder, use a particulate mask, that flux
isn't any good for you.
-Never weld galvanized metal. Zinc becomes airborne, and it's
poisonous; causing symptoms ranging from minor flulike complaints on up
to bad food poisioning plus gallstone-passing symptoms. Cadmium does
this, and also causes permanent neurological damage. Power grinding
gets the stuff airborne, as well. Toilet bowl cleaner will do a
relatively safe job of de-galvanizing, if you're really stuck having to
A good place to start looking up more info would be:
In the long run, a gas shielded wire welder is a lot nicer to use, and
is definitely a worthy upgrade! But I can't recommend a tig setup for
occasional hobby use. Tig needs to be done using a foot control, to do
it well, and quality external control welding setups run over $1000.
That's before the learning begins, then it takes about a year at a full
time welding job to really get the basics down. And mig can do just as
well as tig for mild steel, it's all in the setup and practice!
