Hi all, I'm thinking of getting one or two welding helmets for X-mas.
I've got a Dayton welder in the barn that I've used a little,
with an old flip style helmet. My son (age 14) has gotten into metal working
and would like to try welding. There are a huge number of options.
Here's one review.
http://www.mrwelderreviews.com/review-best-rated-auto-darkening-welding-helmets/
From which I'm thinking of the Antra for ~$50, or perhaps the
classic Miller for a bit more.
Your thoughts?
TIA

everything..and very very well.
Rather large difference in pricing though.....

Ive recently used the Miller and its a nice helmet. But
frankly..doesnt work better than the Harbor Freight.

I may be the least qualified to respond on this. My welding helmet is about 5 years old, and cost $35. I had just read a review of both high and low end helmets ands the bottom line was the reaction time/eye protection was the same, but the ergonomics was the difference.
Within a year of very occasional use, the headgear inside the helmet fell apart. The fix is to buy a quality replacement for $30 or so. That puts the price range back in the total for a name-brand with the good parts.
So I think if I were buying today I'd be shopping in the $100 range just to get decent hardware that will hold up.

I've had two HF automatic hoods. The cheaper one did not easily have a way
to change the batteries and I destroyed it trying to cut the compartment
open. The more expensive one ($10 or 15 difference) was easy to change
batteries, but I managed to break it after a couple years it was quick
enough to go dark, but was slow to go light when you shut off the arc. I
liked the cheaper one better for that because there are some thin metal
welding methods that really benefit from being able to see the weld
bead/spot very quickly ater the arc shuts off. I bought a Miller automatic
and I like it fairly well, but I bumped something with it welding under a
trailer, and broke the adjustment knob off. I still use it all the time,
but I can't lighten the shade easily anymore. LOL. Your mileage may vary.
Regardless of what you decide to use I truly believe an automatic wedling
helmet improved my welding more than anything else except maybe learning
what duty cycle means and that I just need to stop welding and let my
machine cool down when it starts throwing a bad bead whether it has shut
down or not.

with it. (HF unit worked just fine, right up until I drove over it !!!)
Decided I wanted something a bit nicer. The Kobalt is a 4 sensor unit,
solar/Batt. with adjustable sensing, time to clear and shade tint. Also
has a grinding function that I don't use. MUCH lighter than the HF unit
with better headgear.

I'm pretty much a welding idiot.
My house came with a Dayton buzz box, (with a mis-wired plug.)
I made a few bad welds, and then two that are ugly,
but still holding, and haven't used it since.
(I guess I better make sure it's still working and
mice haven't made nests everywhere inside.)
Any other essential piece of kit I need?

just as good as the more expensive ones I've used)
Long sleeve treated cotton or leather shirt/jacket to keep you from
getting a burn from the UV and sparks. (I actually use wildland
firefighting shirts, they are either a treated cotton or Nomex type
material, and they are usually much cheaper than the same thing sold at
a welding supply.
Scrap steel and a solid table with a vice for practicing and testing
your welds.
Grinder w/flap wheels (the great equalizer for the beginning welder)

For completeness, a chipping hammer and wire brush are essential for
stick and flux core welding. A cotton cap and leather shoes help
protect you from hot sparks. When I sit down to weld small delicate
stuff I wear a long leather apron and shoe spats.
Since I can't dedicate a space only for welding I use firebricks to
set up a temporary one shaped like a small barbecue pit. The sides
deflect the wind, conceal the arc flash from neighbors and help hold
pieces in place.
Magnetic angles and C-shaped Vise Grips are often very useful. Clamps
made for welding have copper-plated screws to keep molten spatter from
sticking.
I got by with one 4-1/2" angle grinder until taking on larger
projects. Then I added a 7" one with dish wheels to remove metal fast
and a couple of cheapo 4" grinders permanently set up with a cup brush
for rust and a cutoff wheel to erase small mistakes. The original
4-1/2" grinder has a fairly fine disk for smoothing anything that
could snag skin or clothing. I don't use flap wheels much only because
the edge of a solid disk smoothes inside corners better.
Unless you are only repairing cracks the steel has to be cut to size
first. Either a chop saw or a 4" x 6" bandsaw will serve for that. I
prefer the bandsaw because it's more versatile and accurate. I use
mine a lot for woodworking, with a 6 TPI blade it will smoothly and
accurately cut 6x6 posts and landscaping timbers.

My tool collection grew as projects demanded. The ones I listed were
enough to fabricate a sawmill, a log splitter, and a bucket loader for
my tractor.
The chop saw's advantage is that it will cut thinner or harder steel
better, though both of those are tricky to weld. Its disadvantage is
the shower of glowing sparks that may force you to use it outdoors.
Fortunately my biker neighbors don't mind its loud noise.

model rocket launches. Same idea.
Welding will be done out in the barn, (concrete floor) away from the house.
(neighbors are at least 1/4 mile away.) Is fire that much of a concern?
Maybe a fire extinguisher for the barn is in order... probably not a bad idea
even without the welding.

It's impossible for me to tell from here what your specific risks are.
I have an assortment of water-filled extinguishers around the property
and bring one nearby whenever I'm running an engine out beyond hose
range. So far I've only needed them once, when I saw the old man
across the road lying motionless beside his driveway with the grass
fire his acetylene torch had started creeping toward him.
You probably won't see, smell or hear a fire while you are welding.

Little cement mixer, planar and industrial size router table with many bits,
to the guy who put on a new roof.
1/2 a dozen other buckets/ box scrapers and rakes that I still
drag around with my tractor.

Not sure what you're referring to as the "side arm"; one of the bucket
lift cylinders or the rest-steadies or the boom swivel???
Which ever, there should be no _major_ issue in installing a seal kit;
they're threaded but you may need some serious torque to break an oldie
loose...
I did give replacing seals on the JLG 40H 40-ft manlift main extend and
lift cylinders to the Deere shop in town simply 'cuz don't have a crane
arrangement to pull the 174" stroke 2" bore main cylinder out the end of
the boom. They ended up having to take it to the local hydraulics shop
as they weren't able to break the seal nut loose, either. Took the
other shop three days but they finally did get it.
I've done the lift cylinders on the Deere 4440 w/ 148 bucket; they were
a piece o' cake even after almost 30 yr although it's in pretty near
pristine condition for a late '70s tractor...

I have a 12"(?) chop saw that I hardly ever use because it is so messy.
So messy that I take it outside when I do use it.
The recip saw is not so bad with the right blade. For hard steel, a
cut-off wheel in your angle grinder would do.

I think I'd consider some concrete board as a backup. Maybe some
sheet steel behind if it is to be there for a long time.
I don't have one, should consider it. Hard material would grind through
while a saw requires M42 or magic to cut.
Some just work hardens as you saw.

up for a song to get the feel of pricing, so if you buy one early,
it's 20% of the end price. My backup controller was $13 delivered,
but doesn't have an LCD.

the concept of being entirely self-sufficient during the coming grid
crises. 1) The increasing age/fragility of our electrical grid and 2)
terrorism loom just off the bow of our future. The grid has suffered
362 attacks between 2011 and 2015. Granted, some of those are from
kids wanting to see a transformer explode, but look at this article:
http://tinyurl.com/pc9pfyv (Crom, I hate listening to broadcast news,
but it can carry tiny tidbits of actual information.) Metcalf wasn't
a simple attack and cost over $15 million to repair.

I took it to the local JD industrial repair shop,
and it was a bit of a nightmare. It took them three tries
(and a good part of the summer.)
to get it installed and not leaking.

"Stuff happens" when things are old, particularly...
I'd have taken the lift straight to the hydraulics folks excepting I
don't have a lowboy that'll take it nor do they while the Deere folk do
and pickup/deliver repair work gratis (well, it ain't exactly free but
at least it's in the shop bill :) ). We deal with them all the time
anyway as well as are working farm....

What extra panels are you using? My HF set is only for emer lighting,
and I have 4 lamps set up in the house for it, with 2 backups. I can
also use the little CFLs which came with it, but they suck power. I
picked up three 18w 12v E27 LED lamps for $2 each the other month and
they're extremely bright. They're in the fixtures now, but when an
outage comes, I'll swap them out for the little 3.5w SMD LED bulbs. At
least until I need a whole lot of light for something, like a medical
issue caused by the storm.
HF had a sale on inverters last month and I picked up a 2kW unit which
should be able to drive my electric chain saw, circular saw, recip
saw, or other small tools. All the reviews were positive and said
that they were running table saws, etc. on these units. I have 2 deep
cycle Group 24 batteries for that, and used 2/0 cable between them and
the inverter. I have yet to hook it up and try it.

quickly testing them. Although the frames have some corrosion and the
screws are rusty they still put out the current shown on the labels,
but the reverse leakage when shaded is rather high so I added series
Schottky diodes.
The HF kit I bought in 2011 has degraded to about 1.7A, as predicted.

I can't stand wood heat, but may when the SHTF. Need to buy one of
those little guys for $60, JIC. http://tinyurl.com/qdvp8lt
Does anyone _like_ the smell of wood smoke in the house? Then again,
having heat would be A Good Thing(tm), if the natural gas goes out. I
wonder if they keep generators for the nat gas pumps, and how long
they'd last once the pumps quit, if not. Delivery pressure is 1.5psi,
so it may last a long while.

Does anyone _like_ the smell of wood smoke in the house? Then again,
having heat would be A Good Thing(tm), if the natural gas goes out. I
wonder if they keep generators for the nat gas pumps, and how long
they'd last once the pumps quit, if not. Delivery pressure is 1.5psi,
so it may last a long while.

actually resolves to 0.2A and fakes higher sensitivity by dithering
the raw value. The wires are too small for its full-scale Amp
capacity. Otherwise it's a very handy gadget for checking and
reconditioning older batteries.
http://www.artecing.com.uy/pdf/guias_megger/New%20-%20BatteryTestingGuide_en_LR.pdf
I've found a DC resistance check while periodically topping off a
battery to be a good, quick indication of when it needs attention. I
haven't found a good Net reference to this yet, all descriptions of
battery impedance testing I've seen are from companies trying to sell
fancy equipment for it, just like desulfation.
The Bayite meter is more suited to a fixed installation, with the
shunt in the battery cable and the readout at the control panel. I
added a DPDT switch to reverse the (fused) shunt sense leads so it can
read either charge or discharge current. My inverter is an APC1400 UPS
which can draw over 50A continuously, probably too much for the Aode's
wires.

the house, all leaks draw air in. I've learned how to set the draft
for complete combustion with little or no visible smoke from the
chimney.
That wasn't easy. I have thermocouples on the basement stove with
readouts in the kitchen and bedroom and an outdoor mirror plus a night
vision camera to observe the chimney top. It's very convenient to know
when to tend the stove or the food cooking on it from upstairs.
These are cheap and good enough if you can't find (and fix) surplus
lab instruments as I did.

"A small portion of natural gas from the pipeline is burned to power
the turbine."
"Commonly known as "recips," these engines are fueled by natural gas
from the pipeline."
I never investigated how reliable or susceptible to sabotage the gas
lines may be. Electricity on poles is demonstrably vulnerable but easy
to repair. Our ice storms and distracted drivers keep the crews in
practice.
My automatic backup is the house's original baseboard electric heat,
set to come on at 50F. I have these on the wall thermostat wires to
warn me if they turn on or I forget to set the bathroom back after
showering.
http://www.amazon.com/CR-Magnetics-Remote-Current-Indicator/dp/B006K3O1MY
In an unlit hallway the LED is visible at a much lower current than
they list. There's no sharp 'turn-on point", they just get brighter as
the current increases.

I had to cut that posting short to go and listen to Lindsay Graham and

big-money media circus of larger states. It becomes a good test of
mental endurance that weeds many out.
Bush, Graham and Kasich are experienced leaders with solid plans and

I ripped all those out in 2002, less than 2 weeks after I moved in
this house. CROM, those suck. 40F floor, 65F in the middle, and 90F
at your head when you stand up, all while sucking 4kWh per unit. The
96% efficient HVAC cost me $6k, but it blows the air around and keeps
everything mixed so the temp at the floor is the same at the ceiling,
more or less. I like to stand under the vent when I come in from
outside in the winter. How can you stand baseboard heat, especially
when it's not on PV to pay for it?

I guess with -those- heaters, you can save money and buy the 1AAC
setpoint units for the least cost. And each probably shines bright
enough to light your whole house. <g>

rare. Lighting it may be smoky until the cold draft down the chimney
reverses. Burning one sheet of crumpled newspaper in the upper chamber
is usually enough to get the air flowing up long enough to light the
kindling.
When the stove is up to temperature the draft vacuum runs between 0.08
and 0.15 inches of water, enough to make the air inlet whistle.

The X indicates extension wire which matches real thermocouple wire
only near room temperature.
The dollar a pound price for regular wire was better than a dollar a

the linearization is incorrect. The PC datalogging program corrects
the linearization and shows a difference from the meter's display. The
error is only a few degrees C. When I log the house's heating or
cooling rates I record a few temperature points and times from the lab
instruments for calibration correction. They read within 1 degree C at
freezing and boiling regardless of room temperature.

leakage is only a few milliAmps at 17V, less than 1/10 that of the old
monocrystalline panels. Nevertheless I replaced the shorted blocking
diode in my HF controller so battery voltage and possibly high fault
current couldn't feed back onto the wires running out to the panels.

He should know since his campaign went broke before he recovered and
won the nomination.

My wood stove has an opening such that I can use a small propane torch to preheat the air in the chimney. So I do that and then close that opening and use the torch to light the kindling. I refill the 16 oz propane tanks from a 20 lb cylinder.

McCain's out: too religious/hawkish (strange companions) + other
things. He's not the man I thought he was when he first ran, so I
dumped him back then.
Carson's out: too religious and not nearly tough enough on illegals.
Rand wants illegals here? I like the man, but: Out!

for most of the above to drop, too. I'm waiting until they nominate

I have bought a number of small propane torches at garage sales. So when I refill a tank, I put a torch on the tank. So no problem with leaks.

And I do not mess with the relief valve. To refill a cylinder, I put the cylinder in the freezer and refill after the cylinder is cold. If the tank is completely empty, I may have to cool it and refill it more than once. Best to do this when the cylinder is about 1/4 full. The steel tank does not have much thermal mass.
But to answer your question, yes I have had refilled cylinders leak.

Amorphous silicon is not nanocrystalline, or any other crystalline.
It's a non-crystalline allotrope of silicon.
An old friend of mine was working on amorphous silicon solar cells at
Harvard back in the '80s. They never achieved the efficiency that was
hoped for, but there are some thin-film amorphous silicon cells
around, or there were.

The silicon used in thin-film cells typically is doped, or nucleated
with hydrogen. These typically wind up being nanocrystalline materials
as they're applied to a specific task.
But as-deposited amorphous silicon has no detectable cystal structure,
at any scale. The standard diffraction method for detecting amorphous
materials may be ambiguous at nanoscales, but there is no *positive*
indicator for crystal structure in pure amorpous silicon.

"By high resolution transmission electron microscopy (HRTEM) it was

were generally broad and varied for different samples."
The crystalline structure may simply have been undetectable with your
friend's equipment back in the 1980's.
In the 60's the analysis of crystals by X-Ray diffraction needed a
dedicated round room with film or detectors at precisely positionable
locations on the walls. Constructive interference from the regularly
spaced atoms in crystal structures focuses the X-rays into spots on
the wall like a prism. Amorphous material just creates diffuse fog.

I think there are still amorphous solar cells around. The solar cells in calculators were pretty much all amorphous cells. Cheap, not too efficient, but adequate for calculators.

There also are a variety of experimental multi-layer thin-film cells
that contain a layer of amorphous silicon, and which have much higher
efficiency. Sony has made some, and there is a large installation of
them at an agriculture station somewhere in NJ.
The problem Sony had with theirs, initially, was relatively short
life. I don't know if that's still the case.

amorphous/nanocrystalline silicon. It's been known for decades that
doping with hydrogen causes amorphous silicon to adopt a
nanocrystalline structure.
If that's the evidence, then I think the jury is still out on pure
amorphous silicon.

measure well enough at the atomic level, especislly below the surface.
That's why I objected to your blanket statement that amorphous silicon
has no nanocrystals, in practical mass production versus by
theoretical definition. I suspect the solar panel makers don't waste
the time and money to check for them, and I once built semiconductor
automatic test equipment for Teradyne and was a lab tech at Unitrode.
https://en.wikipedia.org/wiki/Staebler%E2%80%93Wronski_effect
My amorphous Harbor Freight panels will barely reach 0.6A instead of
the 0.86A they are rated for. When I bought them I didn't have the
test equipment to measure their maximum power point so I don't know if
they met spec even then. No one offered a better kit at a local store.
The surplus monocrystalline panels have degraded in reverse leakage
current but not output. At noon they were pushing 85W into the battery
according to the power meter.

Under $100 welding helmets are considered cheap welding helmets, yet they can give outstanding clarity and protection. It should also be noted that the grinding mode and shade sensors may differ. Even the most affordable welding helmets can be equipped with auto-darkening functions, which are regarded a big advantage.

$100, but both are reasonably priced and work fairly well. I personally
prefer the Vulcan, but my son prefers the Viking.
If I were to buy a new helmet today I would seriously consider the YES
Welder hood with the forward facing high intensity LED lights. I prefer
to weld inside the shop where practical so that welding gases (or flux
smokes) are not blown away by the slightest breeze, but lighting up the
work piece is an issue.
