Tig Welding Thin Aluminum 

awesome dude, congrats

5 years since your comment, I hope you are still doing well if not better!

crazydrummerman242 same xD

Nah, I would say, u got the tried and true welder there bud. And the amps to boot. I would use it until it dies! I only have power for inverters, I have three(miller, lincoln, everlast) and use miller syncrowave at work...if I have learned anything, it's that YOU/ME are the BIGGEST BELL AND WHISTLE OF ALL lol good prep, technique, and skill are what makes a machine lay down consistent beautiful dimes, not the machine itself. It helps with VERY specific applications(super thin/thick) but that's amperage range, not bells or whistles. Lol anyway I'm sure u know all this, just figured ide help drive it home. Inverter is good for throwing in back of truck, and using less amps from electrical circuit, but that's about it in my opinion

Slowly and gently sir lol I repair welded 18ga aluminum tubing that broke in half few months ago, turned amps wayyy down, maybe 50-58amps/120hz/66%EN, used 1/16 4043, and made 3/4" to 1" long runs(3 or 4 dabs then stop)let cool for 10 or 15 sec in between passes, it turned out just fine, stronger than before, not an instagram weld but, no blowthrough/holes, and no mess. You have probably already figured all this out by now lol good luck!

Mightiflier..I had two Uncles who both flew sabres there! Never thought I would see that question...sheesh, I am 61!

Beg my pard buts its pretty tits seeing pug here! Ffs

I lost my oxy setup in a shop move but am shopping for another. Maybe one day o will do some braze work

Vic Prk yep, somehow it got late and I left that out.

2% lanthanated for everything

Voltage is defined as 'electric potential'. Imagine two vertical cylinders with a valve connecting them. One is full of water, and the other is empty. When the valve is opened, the water rushes to fill the empty cylinder. In this case the 'water' is an analogue for electrons, and the valve is an electrical switch. A value in volts will tell you how much of a difference there is between how charged two objects are, but it doesnt necessarily correspond to current. Think about getting a static shock - there is a very large voltage, hence when you touch something grounded, the electrons jumping onto or off of you create a 'pop' noise and a small arc. But once you are at the same voltage as ground, there are no more electrons moving therefore no current. In welding, the voltage is what creates a 'desire' for the current to arc and connect to ground, and therefore a higher voltage should correspond with easier arc start. Amps are a measure of electrical current. Amps tell you how many electrons are passing through a certain point in a second. On a constant current (stick or TIG) welder, this essentially corresponds with how much power your arc consumes and therefore how hot the weld area becomes. Hertz are simply a measure of frequency. 1Hz = 1 cycle per second. A higher AC frequency when welding aluminium means the weld is switching between + and - faster, therefore the characteristics of each polarity are reduced (less electrode balling, less 'pulsed' cleaning action). Whenever you see Hz, you know you are dealing with something like pulse, oscillation, etc, that happens periodically.

Frank Reading thx for that you share with us

jfpinkston just for kicks mainly. Also The owners manuals state triangle wave works good for thin aluminum.

I never knew what the different wave forms were used for. The end result turned out nice!

The last weld was not scratch start. I used a Lincoln Tig 175 with high freq start. Scratch would not work well at all on aluminum

Thanks for ur info jody. Very informative. The teachers in my school dont even know how to do a scratch start properly. I tried a couple times myself. Sometimes it starts up the arc so easily but sometimes it just wont start at all even though i keep scratching the steel. Does it matter if i were using a foot pedal by any chance? I saw one of ur video before, flipping the rod to the tungsten. How do u form a circuit by that technique? Im kinda stuck now and no one can give or show me a proper way in school. Its a shame that after paying that much for the school here in australia, i still get the most info and skill by watching ur videos here haha

i have a everlast 250 ex and it has the ac balance control on it.just wanted to know how i could get that frosting effect narrowed down as much as possible.

WAUW, i have the same problem, just changed the option 'best response to newest response and now i see yours.

Unfortunately he don't give any feedback.

@@WALLACE7084 No thats to bad, but i made up my mind en send this one back today, it is good value for the money but not what I'm looking for. I need to weld thin aluminum.
