    Thumbs up

    Welds look really good, the only thing is watch out for the crater at the end of the weld - just keep adding the wire as you slope out to avoid the shrink hole. This is especially important if you're making tanks etc as they can lead to pinholes/leaks.

    Good work - Well Done!

    Gas flow presents an issue at corners. When you weld up to a corner or start at one, the flow of gas gets split up, taking off in different directions on the planes of the panels. The turbulance caused by this can swirl air into the weld area and cause contamination. If you weld lots of corners like that, cabinets etc, try switching to a gas lens so the shielding flow is more uniform and spread out. This has worked well for me in the past.

    Jonnytig... I thought about that gas flow thing the other day.. that's why I turned up the flow a bit. I've been shopping for some gas lens but my local Airgas crew is stumped when I ask about them... Wierd eh? I've seen them but don't know where to find them.. How do you go about getting a fatter more widely stacked bead along 3/32 to 1/8" aluminum. I've seen a guys tig welds before and he builds race car tanks for his own stuff and they all had a larger more spread bead stack on them... It was gorgeous. You've been very informative.. thanks a million..

    HMW... these are the best welds I've done so far... I had some real beauties before this... hahah. I'm sure you could imagine. I've tigged steel and stainless a little bit, but this is my first week on aluminum. It's been way interesting... this makes tig on steel seem even easier!!

    arc-zone.com has gas lenses. i got some CK ones with clear cup and creamic cups off e-bay. just gotta look around on e-bay for a bit to find them. they are a bit expensive in my opinion but what can you do about it right. after all what in TIG isent expensive. i would think most of the on-line places woud have gas lenes.
    i have not tryed one yet but these look interesting.

    Call Jeff Noland at HTP America (1-800-USA-WELD). I got a complete set (.040", 1/16", 3/32" and 1/8") in a kit box for very reasonable cost from him (on sale for $29 + shipping). They work great and Jeff is a good guy.

    Yup. Give him a call with what you need. TIG torch parts are standardized and he's got them all plus the cool stuff like the gas lenses, and pyrex cup kits if you're into that.

    He also has MIG gun parts and plasma gun parts for a variety of different guns. MIG and TIG machines, plasma cutters, spot weld machines, etc.

    I gave up on most "anonymous" ebay sellers for that sort of stuff -- many places never respond to communication and if there's a problem or mistake, you are on your own.

    HTP is a long established company with top notch customer service (like immediate response to emails, they answer the phones, they help you out, etc.). Jeff knows welding and one phone call conversation or email exchange will get you what you need. Only reason I didn't buy the HTP TIG welder was I wanted local (as in within a mile or two) service availability and my LWS carries Miller.
