I'm not sure what you mean by a fully open corner joint. Btw it is a 1/8" thick 1"x2" aluminum tubing.

Something like this?

Yes, sorry I meant the angle. Thanks for picking up on that and thanks for the info.

Which joint would be stronger? I know which would look nicer but is there a difference in the strength? I'm building a cart that will be 2'D X 4'W X 3.5'H. Bottom frame will be 1"x2" aluminum 6061 T6.

I just bought the IronTon. The price was right. $299 out the door with free shipping from Northern Tools. I haven't really started using it much. I made two cuts with it on piece of steel a friend gave to to weld on a post for him. It seems to cut pretty good. The cuts but up pretty nicely. I wouldn...

I meant to write about the cost. I know someone asked on one thread I read wondering if it was worth it to build one or buy one. It would probably be cheaper to buy one if you don't have a full set up of tools to build one. I had to buy a duel regulator, ($100) hoses, and connectors for the argon ba...

Completed it yesterday! (3/13/16) Richard, thanks for the link for the inexpensive duel regulator. (from a different thread. http://forum.weldingtipsandtricks.com/viewtopic.php?f=5&t=9062) I did in the end buy one. I found the cost was close to being the same if I were to buy a Y split with valv...

I was going to say, looks great! What camera did you use? Great depth of field going on there.

Thanks Josh and Richard. I think I might go the Y set up route. I'm going to be welding a tank together that will be 12"x12"x8" with some bungs. I was thinking of buying a piece of copper 12" and drilling some holes into it and clamping it to the joints and with the bungs I was g...

I was planning on doing something like that with the Y split but then I thought why not split it after the welder. Why not do it this way? Is it a bad idea? Also, I would think it would be an inexpensive way to do it? As far as removing the oxygen, that can be done with a small tap of the pedal to g...

I know folks are sometimes using duel tanks, duel regulators or Y splits with values on each side of the split for there purge feed. My question is: Could you split the gas quick release from the front panel of the welder? This in my mind would make life a lot easier. Step on the pedal and gas start...

Great.
Thanks Josh I appreciate it.

I almost bought this one but I was trying to save a few dollars. Do you think I'll have trouble getting the liquid cool with the radiator I ordered?

I wasn't thinking about the increased flow rate. But of course that is a factor. I'll most likely just plumb it back into the tank and keep the flow rate what it will be. My heat exchange that I ordered is 8"x8" cooling surface. http://www.ebay.com/itm/171872360351?_trksid=p2057872.m2749.l...

A thought I had and I'm not sure it would make a difference in it's performance. This is what I was thinking: I was going to add a split on the output of the pump (ProCon pump) and place a valve inline so I can regulate the pressure to the torch. But this is my question. I was going to route the fee...

Ok, I did a few bead tests today. I think the biggest improvement for me was when I balled the tungsten. The arc was a lot easier to control which made it much easier to control the puddle. And no crackling! Thank you for that suggestion! When I had a sharp point I had a lot of crackling and the arc...

This is a lot of great info! Thanks a lot all. Going to get back at it and try all the different recommendations until I get the sweet spot.

I appreciate it all!

First off thanks for the replies. I tested the post flow. I set it at 6s which seemed to help and then set it down to 5s and left it there. I don't have any 1/8 tungsten but ill be sure to get some and try that out as well as trying a not so steep of a grade on the tip. What are your thoughts about ...

Hmm, ok. Maybe a nub move on my part. I bought a container of nail polish remover that said 100% acetone on it. So, I figured that is what it was. Could this be the problem? I hand brushed that piece in the picture with my stainless steal wire brush then wiped it down with the acetone I have at hand...

Floating Ball type. I have the bottom of the ball set at the 15 cfh mark.

Just timed out the post flow. 4s = 4s. I also bumped it to 10s to test and that also was as it says 10s.

The blue tip pic was left from last night. The other two pics are from pre/post the weld beads in the picture attached. Settings for that practice piece which is a piece of 1/8" 5052 aluminum using 4043 filler rod 3/32 Settings not to much different from the OP. 140amps - using a foot pedal. we...

I'm using 4043 filler rod. It's pretty obvious to me when I dip into the puddle. I haven't dipped and I still get the cactus. I'm just running it through my head. The only thing I changed out was the argon tank (because I went through one tank already) and a collet and collect body. On the tank prio...

Kriky here. I currently work as a sound mixer for television and film. I wanted to build a new sound cart for when I'm on location so I figured instead of pay someone $3k-$4k to do it I would buy a Tig welder and take my time learning then build my own cart with out the hassle of dealing with a thir...

I'll start off by saying I'm new to tig welding. I'm very adapt at picking things up. I'm more of a hobbyist and I'll mostly be welding aluminum. I purchase an Everlast POWERTIG 210ext and I'm using the 26torch with newly purchased collet and body. I can run some pretty nice looking beads then at ot...
