Diamond group will send a free sample if you call them.

I felt pretty adventurous one day and asked for the 4% thoriated one.... Still dips in the puddle when my hand moves the wrong way, not good enough then, gotta be puddle dippin' free.

wrong amperage for the tunsten size being used,affects weld quaility,grinding long and thin is a crutch to get by.
I understand having to use what is available. But choosing the wrong size seems so unprofessional.

I just got off the phone with DGP, Cryo T is meant for steel, not aluminum. They also take into consideration if you have an inverter or transformer type machine.

Apparently the Chinese is the ones making E3 so the QC is probably non existant and is a copy of the Tri Mix.

I keep getting variying results with my E3's sometimes they are great, sometimes not, last night I was trying to weld aluminum outside and they just kept sucking.

Now I am getting a sample of their Tri-Mix since that's what's recommended for my inverter machine when doing aluminum, I guess I can use it for steel and aluminum but I am really wanting a better aluminum electrode.

Yeah if you could find some tungsten that doesn't dip you make sure we are all the first to know. or maybe some combination of elements that resist certain metals or a magnet for steel that repels the torch if you get too close...

I think Im on to something here

or maybe not...

That would be awesome. I used to sling the hose up through my drop ceiling in the shop to try and help the dipping phenomena, still dipping it like fries in ketchup.....

My machine is only a DC welder so the cryo T would bealright for me to try. thanks for the tip on a free try. Thanks :D

Did they give you any info on advantages of the 4% thoriated over 2%. I wonder does the oxides just deteriorate slower than 2%. Might be useful with the smaller diameter tungstens. Typical dip before I wear it out.
why use standard nozzles after gas lens where invented. Kinda of like starting fires by rubbing sticks together.

No, I didn't ask. I stay away from that cancer causing stuff..... Like thorium is my biggest concern in welding :lol:

I got away from these thoriated ones but figured I would give it a shot. You can call them and ask them, they are pretty helpful. I am getting some samples now so I will see :D

Might want to read up on Thorium before you lump it into cancer cause from hearsay info.

I'm not concerned with all the scares I use 2% thoriated on steel. I like the way it performs and will continue to use it. I use 2% lanthanated on aluminium holds a taper better. However I'm curious as to what advantages the 4% has, might be useful. Ever used a piece of tungsten and after awile you notice that it just doesn't seem to put out same amperage and you have to push further on pedal or starts seem to not be as crisp even though tungsten looks pretty good and hasn't been dipped. As you weld with it the tungsten changes. My limited understanding of it is that the grain structure changes and the stuff added to it gets vaporized so that the chemical make up starts to change. I notice it more on smaller tungstens that's why of wonder if the 4% holds up better. Curious as to what advantages and disadvantages it has over the 2%. Take the lanthanated tungsten as an example. I like the way it holds up under an AC arc using the 2%. However I find the 1% and 1.5% total garbage which is what the local places carry.

Thanks for bringing that up. It explains a lot. Diamond Ground Products confirm your thoughts.

" Migration and Evaporation Rates: The migration rate, or diffusion rate as it is often
called, is the rate at which each of the different oxides naturally travels from inside the
tungsten to the heat at the tip of the electrode. The evaporation rate is the rate at which
the oxides separate from their metal component and are emitted at the tip of the
electrode. The optimum-performing electrode is one that has a balance of good
migration and evaporation rates. If the migration rate is slower than the evaporation
rate, then there will be an inadequate amount of oxides arriving at the tip to maintain a
consistent arc and the tungsten may be reduced to the performance level of pure
tungsten. If the evaporation rate is slower than the migration rate, the oxides will be
crowded at the point. If both of the rates are very high, welding properties at the
beginning of welding will be great, but all of the oxides may be used up quickly. "

kiwi2wheels, yep that's what I was talking about. Their description is a lot better than mine on what's going on. Explains the crappy performance from cheap import tungstens that are prolly caused by poor quality control of the mixture and maybe even the purity of their base components.

Another good description from link provided by Kiwi2wheels. Copied from the pdf

Manufacturing Variables
Grain Size and Structure- The picture below shows the molecular structure of the inside of a point of tungsten and how it is
divided into smaller groups called grains. These are very important because it is primarily along the boundaries, or borders, of
these grains that the oxides migrate to the tip. It is much easier for the oxides to
migrate from inside the tungsten to the tip on the grain boundaries than
it is for them to migrate within the crystallized grains. In manufacturing
the tungsten, the smaller the size of the grains, the better the oxides will
migrate to the tip because this produces more paths for oxides to use.
Therefore, the smaller the grains, the better the migration of the oxides
to the tip. It is a very difficult process in manufacturing to minimize the
size of the grains while maximizing the consistency of the oxide
distribution and maintaining the proper quantity of oxides. This is one of
the reasons why there are differences in the performance of tungsten
produced by different manufacturers.

During the extreme temperatures of welding, the grains have a tendency to combine with larger neighboring grains to form one
large grain. This is called grain growth. If a continuous flow of oxides at the grain boundaries is maintained, this serves to
surround the grains and pin down the size of the grains and keep them from combining. Thus, oxides are grain growth inhibitors
(they also promote electron emission, which will be discussed later in the section on work functions). When tungsten runs out of
oxides in any area, the grains combine readily and the tungsten is reduced to poor performance because of the lack of avenues
for oxides to move to the surface. In the example in the picture above, notice how this 2% Lanthanated electrode still has a very
small grain structure even after one hour of welding time at 180 amps on a 1/16” electrode. As will be explained in this guidebook,
this is due to quality manufacturing by this tungsten manufacturer and the oxide properties of
2% Lanthanated tungsten.
Oxide Distribution and Size – Perhaps one of the most important variables in the performance of the tungsten is the oxide
distribution. This is also the most obvious factor in determining whether or not a tungsten manufacturer is a high quality producer.
It is extremely important for the oxides to be dispersed within the tungsten in a homogeneous manner. As discussed above, if
there are any areas with little or no oxides, the grains will easily combine under heat and restrict the flow of oxides to the point.
Even though there may be plenty of oxides within the tungsten, if they cannot travel to the point and emit the oxide, the
performance of the tungsten will be restricted. On the other hand, if too many are clumped together in one area, bottlenecks will
occur to prevent the oxides from getting to the point. Finally, the selection of the raw material oxides to use in manufacturing is
also important. Higher quality oxides are smaller in size, which allows them to migrate to the tip easier.

I have read up on Thorium, it starts radiating its radioactive stuff when its being grinded or hot. At least thats what I remember.

You probably get way more radiation from welding than you ever would from thorium. Newsflash...lot's of things about welding and metal craft is bad for you. I use thorium dust to flavor my margaritas. 8-)

I can think of anything that could cause other health problems breather than that radiation...

Oh wait-welding galvanized, welding stainless, eye problems, aluminum dust and oxides, breathing any fumes (especially flux core and stick in a closed space), in sure acetylene let go before you light has its problems and I'm sure the exhaust isn't good for you, and then all the burns aren't good for your skin and could cause infections. Not to sway people off, there is protection against almost all of these. Just take them.

One of my best friends is 91 years old...worked for my dad doing asbestos in the 70's, poked a hole in his dust mask so he could smoke his stogie while he worked, still smokes cigarettes and cigars and drinks a 12 pack every night and just retired 9 months ago..Thorium is a health threat? Really? I think the actual participants in life live longer than the spectators. I'm a participant and have the scars to prove it.

You get more radiation from getting 1 X-ray at the dentist than you will from tungsten. Unless you start snorting the dust under the grinder.

I am starting to get the idea someone didn't catch my sarcasm. But let me hammer the nail to the point here.

There are so many warnings about all and every thing that will kill you, everything is dangerous and that's how it is. I am not worried about Thorium's slight alpha radiation or whatever its called nor so much from the fumes of welding.

I wear a mask and protect myself as much as I can stand cause when its hot outside, I will gladly carry a burn on my arm than having to sweat my way through a job, Florida summer is like a 24/7 sauna, it's so wet outside its retarded.

Spent the last few days, on my spare time, reading about thorium.
Apperantly Thorium is naturaly occuring and everyone on the planet is injesting it. The percentages are small, or should I say microscopic, or even smaller then that. It usually passes through the body. Yes the worst way for it to enter into your body is though and into your lungs.
That being said, I wonder how much asbestos I have breathed in in my life as a Plumber. Pipe coverd with it, Vermiculite in ayyics as insulation. Floor tiles with asbestose in them, Bricks with asbestos in them. The list goes on. Apperantly my risk of a heart attack are greater. Thats because Ive had one. :o :D All good now.But thats getting of topic.
Wear a mask while grinding ANYTHING. just common sence.
If you dont like thoriated tungsten thats fine by me dont use it.
Now getting back to what tungstens are good, I have had the chance to try Ceriated tungsten Not sure what percentage.
Ive tried it on Stainless with a DC tig or GTAW, If you prefure, and it worked perfectly. best tight arch ive seen so far.
So I am from now on using ceriated tungsten for stainless.
I will how ever, as money permits, keep trying other tungstens as well. :D :D
