Here is a job I got in the other day. I had no Idea what to weld it with , so I went to the local Welding supply and talked to the Old guy. (70 something) After a few technical questions (what color is it) they handed me 2 kinds of rod. One was pure brass and the other was Idunno. I think it was phos bronze, but I have to look at the invoice tomorrow. I also have some Phos bronze electordes in 2 flavors. One is 3/32, runs on DC-, the other is 1/8" and runs on DC+. I cleaned it up and tried the electrodes first using the specs on the box. No joy. Next I tried the tig rods. The pure brass rods spit and sputtered, the other one (Ok, I'm embarassed, I can't remember names for beans) worked fine.Here is the unitHere are the cracks and old weldsTime for some prep and clean up of the old welds. SEE the old weld? I was getting sparks from the die grinder and 4 1/2" grinding wheel. I have no idea what was used, but all of it had to go.Last edited by David R; 10-24-2007 at 07:24 PM.Real world weldin. When I grow up I want to be a tig weldor.
Reply:Here is the first weld. I don't walk the cup, but I "ride the cup". I rest the cup on one surface and let it help me keep a steadier bead.Here is one side completedAnd a close up of my pride and JoyReal world weldin. When I grow up I want to be a tig weldor.

Reply:very interesting... i never thought that you coudl weld brass. i figured it would melt too quickly and jsut run all over. what is that thing anyway? it either looks like a cage for a small child, or an end table... possibly both? hehehehe looks a little heavy and dirty for an end table.later,Andy
Reply:Its a thingamajig. Probably weighs a hunert pounds. I used my arcmaster 185. I had to push it to the floor and wait a while to get a puddle going on the thick stuff. I was thinking about hooking the torch to the V350. Once I welded an inch or so, it worked great.After I got home, I read the book and I should have preheated the whole piece to 500 or so. I put a couple of holes in the thinner stuff, but just filled em. I pointed the torch directly at the thick stuff. With preheat, the electrodes may have worked too.DavidReal world weldin.
