Thats what we use. But the color has changed, they are grey now (at least in the brand we buy).
Rob-D, I'll have to loo into that.

LD, if you really want a brain focus, finger burner give this a shot, 28ga copper sheet. Ugh this project is killing me. Doesnt help that im using #6 solid house wire, probably around 3/32.
I don't know your application but I simply solder sweat copper sheets. I built a crook for my chimney 20 years ago and it is still in good shape with this method. If the seam is stressed I use mechanical bending to add strength.

Strictly ornamental Rob, didnt want any discoloration in the blend work. Just finished the blending and polishing about 2 minutes ago! LOL
Right, didn't think of that!
I know a lot of guys are swearing by 2% lanthanated but I haven't tried it yet.

I could get away with red, green, orange, and gold, but I run old transformer machines at home and at work. For me it seems theres a place for all of them, because they only effect bead width. The orange ceriated is pretty durable tho as far as contamination goes, screw ups and stuff. Im gonna run a test tho with all of them, but im leaving town for a few wks starting tomorrow so ill have to wait till I get back. Bowhunting 3 states, yahooo!

I don't remember the % of lanthanated I have. I quit using it because the tip splintered on me at high amps.:confused3:

I have been using 1.5 Lanthinated, Blue band.. 1/16.. my welder cant go high enough to really need larger anyway. Depending on which chart you look at the 1/6 lanth. is good for almost 150 amps. But I dont think I have ever welded above 100.. Heck if it is bigger stuff , I use 7018!. I know some guys do root passes on pipe with a TIG. but I just use a TIG to repair and make little things mostly. Seems to work for me.

James if you really want to improve your Tig welding skills get some 2-inch to 4-inch pipe, grind a 37 1/2-degree bevel on it, use a 3/32-inch drill bit to set the gap. Use 1/8-inch filler rod, and make 4-tacks, 3, 6, 9, and 12-O'clock. Place it on a 45-degree angle, (6-G). When in the 6-G position you have to use both hands to make the weld! On the right side of the pipe you'll hold the torch in your left hand. On the left side of the pipe you'll hold the torch in you right hand. Trust me, this will really improve your Tig welding skills.
First picture is the inside of a pipe I Tig welded. Second picture is of the outside of the pipe.
