Some aluminum help!

admin

So whenever I go to try and weld aluminum my tungsten always forms a ball at the end of it?? What the heck am I doing wrong, all I have is the 2% throiated tungsten, maybe its the wrong stuff? I keep forgetting my camera to take pics tho HTP Invertig 201Lincoln Idealarc SP250Miller 180 AC StickBy farmall:They should have held the seagull closer to the work, squeezing evenly for best deposition.
Reply:That is pretty much normal if you are using a transformer machine.

Reply:What are you using for a machine?  2% Thorated will ball under the right conditions.  It can also split.  Bot only on AC.DavidReal world weldin.  When I grow up I want to be a tig weldor.

Reply:By the nature of AC current, you will form a ball on any tungsten.  1/2 convex and 1/2 concave, makes a ball.    JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases.  There all here. :
Reply:I dont understand current really. I am on an old MIller, it just says model 320A its a freakin refridgerator. I had it on AC and just left the amperage where I usually weld and just use the foot control to work the amps. So a balled tungsten is ok?? I think I melted one of my cups when I tried it I dont remember. I am just looking for some advice for when I gfet back down to the shop I can mess with it. I dont know the diameter of the tungsten....HTP Invertig 201Lincoln Idealarc SP250Miller 180 AC StickBy farmall:They should have held the seagull closer to the work, squeezing evenly for best deposition.
