Well everyone, thanks for all the input. I was unsuccessful today unfortunately! No matter what I tried, I could not get the arc to be stable, I couldn't keep the tungsten from contaminating, and over all a sucky day! I literally tried everything..... changing adjustments, cups, gas flow, voltage, f...

Sorry I do not remeber the name of the video. But if you go to the main page there is a video on there called aluminum drill. If you pay close attention to jody's technique you will see you will see that when he moves the torch forward he uses a nice tight arc meaning the tungsten is close to the m...

With the set up I mean what are you using on the torch. Standard or Gas lens and what size cup? For Aluminum I like a #5 standard cup you don't need to ever use a gas lens (unless you're welding it on DC). If you can lay a bead with a different machine without these problems it might be something t...

And if this helps in what you need to know to help me............When I start the arc, it seems to drift and not focus where I want it. The arc is not tight at all. Of course the tungsten "balls" pretty quickly also. (This is an air cooled torch.) I have used the miller syncrowave at work ...

aluminum has a attraction to the tungsten. Look at some of the videos Jody has on here to see his technique. I have watched a LOT of his video's but haven't seen anything specific on that. Do you happen to know the name of the video that would help (for this case) or can you post a link? I will GLA...

What kind of set up are you using? What do you mean by that? I have the knobs set at what Jody suggested (about 120 and 75), I have the pulse off, set in 2T, using the foot pedal and AC selected. With this machine, the foot pedal over rides the amperage control. (Not sure if all machines are that w...

Oops, I meant the machine is a 256PI not a 250PI.
Also, I meant to say that I have welded in my garage for years BUT....I have no formal training at all.

Thanks again.

I've welded in my garage for years. Mostly mig and stick. I recently got a Longevity 250PI inverter weld all that has a TIG. I never TIG welded before getting this machine. I have welded carbon steel just fine, but I have not AC welded with this machine until today. I have some aluminum I'm trying t...
