That’s awesome bud. Always great to hear success stories.

Aaron Laughlin yea that metal bucket probably not the best thing. I bought a simple drummers stool at first until I could upgrade. Now I have a Vyper chair. Had it about 2yrs or so and I love it.

Aaron Laughlin no the purpose is heat input. I never let the previous puddle solidify. I back off the pedal just enough to keep the puddle flowing in its molten form. When I add filler, I give it more pedal to flow the puddle out to the desired size.

Practice practice practice.

I’ve had that happen multiple times. Mine always seemed to be due to sweating and propping my bare arms on the table. Electricity always takes the path of least resistance. I started wearing sleeves and I don’t seem to have that problem anymore.

I have a small slip roll in my shop that I use to make small rolled patches for Aluminum fuel tanks. Besides that I have little experience with them. Cut off wheels are your best option if you don’t have access to a small plasma. Can’t wait to see the end product.

Your off to a great start, go check out some of my videos on Aluminum and see if any of it helps. Glad to have you on the site.

Congratulations guys. Can’t wait for the next challenge.

Here’s something I read a few years back. Thought I’d share with you guys.

. All porosity in aluminum welds is caused by hydrogen. Liquid aluminum can dissolve a lot of hydrogen, but solid aluminum can dissolve almost no hydrogen. So a molten aluminum weld sucks up any hydrogen around. As it solidifies, the weld tries to get rid of the hydrogen. If it can, everything is OK. If it can't, you get porosity.

So where does the hydrogen come from? Basically, there are two sources. The first is any sort of hydrocarbon, like oils, greases, and solvents. The second is water vapor. The temperature in a welding arc is more than 10,000 degrees F, hot enough to break down these substances into hydrogen plus something else.
