How to TIG Weld Aluminum and Get the Stack of Dimes Look, Even With an Old TIG Welding Machine
An additional tip for reducing the amperage needed to Tig weld aluminum is to use a 50/50 or 80/20 argon/helium air mix. The added helium really makes a difference. Not only will you need less amperage, but the aluminum will puddle quicker and cleaner than using pure argon. Trust me about this one!
Lastly, I recommend using as small a Tig cup as you possibly can. Some people refer to them as Tig welding nozzles but in any event it is the ceramic tip that goes on the end of this Tig torch that directs the shielding gas to the weld and protects the tungsten electrode from being oxidized. Using a modest Tig cup requires less shielding gas. For example a #7 cup might require 15-20 cfh whereas a #4 cup only will require 8-10 cfh. That much less gas blowing relating to the part makes a change in the amperage needed. In addition to the following, the arc energy that is dissipated by means of cathodic etching (also called cleaning action) will only go where there is usually gas shielding so there does exist extra arc energy on the market to be focused at the weld puddle.
I reminded myself of these tips just last night when I welded some sort of 4 inch machined ingot of 6061 aluminum which has a Miller Dynasty 200 amp Tig welding inverter. I needed to replace some material that had been miscut by a machine shop on the prototype part that already had lots of machining time invested. I used the actual welding tips I mentioned earlier in this article: I placed the part relating to the stove and preheated it to around 200 F (exactly one alcohol). I used a 50-50 argon/helium mix, and I used some sort of 3/32 dia thoriated electrode with a #4 ceramic Tig nozzle. I was really surprised as i only needed about 170 amps to get the job done, even though the element was pretty massive.

When things go wrong when TIG welding, its not a hundred things you are doing wrong. Its usually only 2 or 3 things. Sometimes changing only one thing can make all the difference. But in the event you don't have any idea outcomes look, you certainly will just keep on screwing up. They say madness of insanity is doing the same damn thing more and more and expecting different outcomes. Another manner of putting it is:
"if you always do genital herpes virus treatments always done, you certainly will always get what you always got! ".
I have trained several welders, May possibly noticed that things that learn the best and quickest are the ones that think about what they are doing. Rather then getting pissed off and slinging their welding helmet across the shop, they look at their weld and inquire themselves what they did wrong. People think. People make some changes. They require help.
This 3 things I discover TIG welding Noobs doing wrong more often than anything else are generally:
