    Default Good advice for those that weld aluminum

    If you think your aluminum welding skills have suddenly taken two steps backwards...

    Check to make sure you didn't pick up a 308 stainless steel filler rod by mistake.

    And, no Craig. You may not post in this thread.

    "Boy, this Al filler rod sure is stiff"

    How about a "Dumb stuff you have done while (trying) to weld" thread for stuff like this and my gas mix- mix up. I bet there are some good ones.

    Forgetting to turn the gas on with the mig is a fun one. It's amazing what a difference a little shielding gas can make.

    Hehehe.

    And it was fighting the heat. Didn't want to melt into the puddle. When I would try and put it in, instead of melting it would poke a bigger hole into the joint.

    Indeed. I did that recently as well. I had shut off the gas because I was about to stop for the day. Went inside for a few minutes, then realized I had a little time left, so went back into the garage and started to weld again. Forgot about the gas. Oops.

    I should shut up now or else nobody will ever hire me.

    I've run the argon tank empty. Same result as forgetting the valve, just more gradual.

    Another tip.... do not store your magnesium rods within10 feet of your aluminum rods.
