Try 5/32, 3/16 or even 1/4 inch tungsten, the larger diameter tungsten can handle more current and have greater heat input into the part because it can distribute the heat more effectively. I agree as well that helium definitely helps with thicker aluminum. Helium has a higher thermal conductivity than argon thus inputting more heat into the part. Helium has higher ionization potential than argon thus it require more energy to ionize helium and produces a hotter arc. And dont forget too since helium is less dense than Argon it will require slightly higher CFH to achieve proper shielding. Amd you should look into a gas mixer for properly mixing argon and helium mixtures because it blends the argon and helium more accurately to the proper proportions of your specified mixture and achieving optimal high quality welds.

How much did the bottle of helium cost you? Manifold looks killer. I’ve always wanted to try some helium mixed in.
@@thedude6650 i want ti say around $125 i think a 125 size is $250
