Looks like it's DC only. It is possible to weld very thin Al with DCEN, but it is difficult, and not good practice. 2% thoriated tungstens are all you will ever need. Stainless that thin will need around 15 amps, and a quick hand. You can get filler wire for TIG down to .040, maybe thinner. You will...

I don't think your tank is supplying enough fuel. It looks and sounds like if you could give it just a little more gas it would run on its own.

You may want to keep an eye out for a 20lb tank.

If you can find a tightly wound coil spring with an I.D. slightly larger than the tubes O.D., slide the tubing inside the spring and try bending it around a pipe. I've used this method before and it helps alot, the spring tries to make the tube keep its round cross section.

Mike, if you can do that with a torch, TIG should be a breeze. Nice beads.


P.S. get some solarflux!

For a home built refractory, I will highly recommend Dave Gingery's book. My father built one, and it has held up for about 20 years now. I'll try to post a pic or two in the next few days. It makes for a very nice furnace. As a matter of fact, all of Gingery's books on DIY tools are unbeleivably go...

WHOA!!!!!!!!!

Just make little batches! A tablespoon of the powder will cover ALOT of weld seam. Mix it thick, if it doesn't paint on well with a brush you have added too much methanol, jst add a little more solarflux to it.

I've got an air nibbler, I've used it quite a bit on 22ga stainless. It cuts wicked fast, and doesn't leave any burrs at all. I find it hard to follow a line though. I use the nibbler to cut out the part 1/4" or so from the cut line, this makes for easy work with the snips finishing up. The cutter i...

The solarflux will dry almost as quickly as you can apply it.

You aren't going to have much luck until you backpurge or solarflux. Your local welding shop should have solarflux. It's kinda expensive, about $40.00 for a 1lb can. That can will last you a very long time though.

Try backing your argon flow rate down to around 10-12 CFH, and make sure there is no wind, or fans blowing in your welding area. Backpurging or fluxing will be a huge help.

What diameter tungsten are you using? What size gas cup are you using?

Bill: Good to see you posting again. Welcome back!! Your expertise and informative posts were greatly missed! Dave Please DON'T consider that a post--just an alert. I'm sticking to my decision not to post on the Forums. Was that one a post? Seriously Bill, if you have something to share... Well tha...

With SS, prep is everything. It needs to be absolutlely clean, I want to use the word sterile. With thin SS sheet, you need a perfect fitup, no gaps anywhere. You need to be backpurging. Not doing so will cause "sugar" really bad on the backside of your welds, and with thin stuff it will cause you t...

I'd likely take a few, how much $$$??

Fix a flat. http://youtube.com/watch?v=T_6qV50NFgY That's an old trick, crazy, but it works. I grew up around construction sites with my dad. I've seen dumptruck guys do that a few times, though they did it much more gracefully. They used it to pop a tire back on the bead if it got rolled off while...

I'm a little confused. I'm not far from you, Nick. I would imagine that we would get same type of tank if we exchanged ours at a gas station. I've never had any trouble with the fuel shutting off, even with a 50lb lockwood. Try exchanging your tank for a different one and see what happens, it's wort...
