thanks!! thats very very good to hear for me!
id say for everyone reading this...the best tips i can give from my own experiences (keep in mind i have only been doing this for about 5 months, ive used 6 big bottles of argon)
1) cleanliness!!! use acetone or denatured alcohol and a new paper towel to clean everything you are about to weld. i personally dont clean my filler rod, i havent noticed a difference....
2) prep your metal, and what i mean by this is gaps...this is esp true in aluminum welding, keep your gaps as small as you can, 1/16" or smaller....if you can do this and clean the metal before you weld it...you will instantly see a difference in your welding!!! a good difference! also deburr what you are welding before you weld it, if you use grinders...make sure its a dedicated grinder for whatever metal type you are using..ie done use a grinder/sander you use for steel on aluminum
3) learn to sharpen your tungsten effeciently and sharpen it the correct way the first time. literally buy a small grinder with a sturdy tool post. use this only for your tungsten and you wont get a weird arc anymore
4) torch angle!!! anyone with even the smallest experience in tig welding will know that torch angle plays a huge part in how your welds come out... with aluminum i find it best to be nearly straight up and down or pointed directly into a crack. gives you the most heat where you want it
5) above all else...take your time!!! i know we all wanna rush and get shit done oh so fast since time is money..but if you want quality..you will take your time. like my stainless steel welding for example...i weld 6 beads and stop, yet you cant even tell where i start and stop! same with the aluminum tank above. more time you take to prep the metal, clean it, and finally welding it...the better it comes out...always
guess if anyone has any questions hit me up

im no pro but i will be very soon!!
and i mean there are a bunch more things you have to know but once you get more seat time you will learn how to change the small things quickly and not get so frustrated
