This is part 2 of making an argon purge chamber.
This will be a very useful tool for tig welding small parts.
Whether you need to tig weld a gun part, modify a small wrench, fix a misdrilled hole, or weld a small part made out of titanium, ( like a titanium foot peg for a dirt bike)
...full argon shielding can help a lot.
For Tig welding small parts like gun parts, or small parts made from titanium, a small purge chamber like the one above can be a great help.

Now that I have proven the concept, I will experiment with other media.
maybe copper balls, stainless steel balls, glass beads, polished rocks, etc.
I think copper balls is going to be the best bet but I am having a hard time finding the right size.
My friend Jonathan Lewis, made a small purge chamber using simple and inexpensive materials.
A meat loaf pan, some annealed copper tubing, steel wool , and a few other items.
And his version actually worked quite well.
BBs are made of carbon steel and are copper coated.
There is a definite risk of contaminating stainless steel parts and there is also a real risk of melting BBs to the part being welded in this small purge box.
That is why I am going to try other materials...
I will post another video when I figure all that out.
