Don't mix your stainless rods with your aluminum rods... http://bbs.homeshopmachinist.net//frown.gif

Another man sacrifices his reputation for the good of all! Is there more to the story?

I did that once. welding aluminum and grabed a stainless rod. that stuff don't like to mix

Don't mix sparklers with welding electrodes.

Had a guy at work kept wondering why he couldn't weld aluminun with the wire gun,checked out the machine,checked out the gas,found the stainless weld wire!

Only that it took me almost half an hour to figure out why I was getting this horrible looking bead and my tungsten kept burning up! Checked amperage setting, argon flow, changed torch cups, changed tungsten types...Lesson: never overlook the obvious.

And NEVER put dynamite in the road flare pouch in your road kit. (wile E coyote).

Normally I can tell the difference in aluminum and stainless by feel.

I did know a mean drunk that cleared a bar by throwing a road flare in with a lit fuse on the nail.

I can rub Aluminum between my fingers and tell it is Aluminum by the smell. Can't do it for week after eating chili - I don't light matches then either! http://bbs.homeshopmachinist.net//eek.gif http://bbs.homeshopmachinist.net//biggrin.gif

Well, I guess bad lighting and gloves got me there. Usually when I pull a fresh rod, I'll loop the end of it so I don't poke myself in the eye with it, but I didn't this time. Had I done that, I'd have noticed right away of course.

Sounds like forgetting to turn the gas on for the MIG......I do that at least 1 time in 5......
And what's really bad is, I always mess with the wire feed and check the heat BEFORE I think to open it up. http://bbs.homeshopmachinist.net//biggrin.gif

X man,

Thought maybe you had stored them together and when you went to use them all you had was a handfull of white metal powder. Corrosion from dissimilar metals can raise hell in the shop.

i have been there., now i make sure the rod is pliable beforehand. but something good came out of your post, at least for me. i like your idea of looping the end of the filler rod. i cant tell you how many times ive jabbed my neck or it got under my hood. i feel like such a fool for all of that blood that i lost because i couldnt think to do something as simple as that! haha

Hey, maybe that corrision isn't all bad. Put a few choice metals together, water it, then after it's all powder, there's your raw material for sintering a new metal alloy, or is that a new ceramic, hmm.

We've all done similar things, X.. I wasn't knocking you.. Last thing I done was try to shave a piece of uhmw with a router bolted to a table. At least I had the brains to hold it with pliers. My fingers were smarting so bad from the blade hitting the pliers I thought I had lost some. ANd then... yeah sometimes weekly..

Steve, in light of the event that led to my starting this thread, I feel kind of silly telling you this, but you can also use different style loops on the ends of your rods to tell them apart.
