Anybody tried K&G's welding flux, I got a can of it on a whim and am very impressed with it compared to 20 mule team borax. Is it just anhydroise borax, or something else? Seems kinda high, but I used only a couple table spoon fulls where I'd use a cup or more of 20 mule team so it may actualy come out about the same and not eat up my forge as bad.

If it's just anhydroise I know now to see where I can get some.
 
I suppose that I am in the same boat as you, I have been using it here recently and it does seem to work better than the 20 mule team borax. However I do not know the specific ingredients.
 
Forge welding flux is made from anhydrous borax,boric acid,and often several other ingredients,even powdered charcoal. 20 Mule Team Borax is just plain borax,with all the water molecules still in it.You can make your own anhydrous borax,but it is hardly worth the trouble.While plain borax will work,welding flux will work better,IMHO.I put it under the "save a dollar in materials,spend two in labor " theory.Don't you want your damascus welds to be the best and easiest you can get?A can of commercial flux lasts a long time,and does not cost much.

One thing that I have noticed that helps with the plain 20 mule team borax is to keep it in a very dry environment. I store mine in a welding rod cabinet and it keeps the moisture content in it very low. I suppose an insulated box with a light bukb in it or something similar would provide the same results.

I have used comercial fluxes and some contain iron or steel filings. They work great for mild steel but Im not sure I like the idea for damascus. I dont know about the formula of the one you are trying ..
 
I'm pretty sure it doesn't have metal fileings, it looks a lot like powdered salt or maybe suger, almost looks like it has sand in it. It definatly works a heck of a lot better than 20 Mule team and stays on the billit and only takes a very little bit. I'll see how long this can last, it may wind up being cheaper in the long run.
 
I've used the K&G flux and 20 mule team with good results. The only time I had any difficulty was when I didn't get the temp. hot enough inthe center of the billet. You might try to store the flux in a military ammo can with a gasket on it. I use one for a quench tank and for my vermiculite, works great.
