This video was shot more than a year ago, and we've since upgraded video equipment specifically to capture better arc shots. TIG is especially tricky, but we're working harder to get you a better look at these, nicer close ups are critical. We hear you.
This was a great video. He really explained the various hz settings and why.(no other video discusses this) But i agree that arc shots are needed. from the brief weld shots that we did get this guy actually looked like he had a great looking weld.
i wish he would have shown the final weld. the tack at the bottom of the plate he added in the middle that is about 4 beads long cracked...... you can see it clearly but at least its just a tack.
thats a nice cummins block. If you guys do another repair demo on one of these, feel free to mail it to me so i can put it in my truck to test it for the longevity of the weld lol.
I have to ask, what is up with that 3/4" long weld with the crack through it at 3:50? Other than that, I completely agree with how he set the machine. I don't think you need more than 180-200 amps positive to blow off the oxide, and you can max out the negative and weld into real thick material without destroying your tungsten. I've run the Lincoln Invertec, Dynasty 200, 300, and 350, and I am comfortable saying the Dynasty is the best machine out there right now. Of course, if you can't weld in the first place, no amount of fancy settings is going to fix that for you.
nunya bizniss Tack welds sometimes crack due to the tensile stresses induced when welding other areas of a component and assembly. The weld in question is simply a tack and typically would be ground out or fully consumed in the final weldment. Please let us know if you have any further questions.
+Miller Welders ..nice work...excellent reply to 'nunya'...Obviously the long weld on the other side of plate will pull against the tack...I'm currently doing all my TIG with a 300A 1956 P&H....looking to buy something like what you're using...
Doug Ankrum They tacked it in a hurry, and let it cool too fast. Which is fine, but it looks a little sloppy. If you had let the metal get warm enough and tapered off the weld, you wouldn't have a crack. You owe it to yourself to get a modern machine, square waves make a great difference, and frequency control is nice too.
I totally agree. All this talk about being able to weld right down the middle of the seam, and not one single good close-up view of the actual welded seam!
I get alittle confused by these vids, ive been welding aluminium for years, (not just alloy tho) mostly on boats were the apearence is just as important as structural integrity but i the only things i ajust is amps and gas.
guys your vids could be so much better, atleast give us a look at the welds after there done coz it seems like you try to hide them and thats never good.

very informative Chris, can you comment on gas setup, pre flow,straight argon? and flow rate.
Thanks

why is there only sound on the left side in all your video's?

+Miller Welders can I buy Miller welders in Australia?

Some good info- but show the weld please! All the talk about how good it welds and not one shot of the thing it actually does.
i love the dynasty 350, great machine

wow what a machine :) never see same
Really Miller
Thank goodness your machines aren’t build the way you make videos.
Left side audio
Perfect

Most likely because you had the skill to compensate for all the Bells and whistles ;) Which in my opinion is the best bell and whistle of all
do you see the crack, funny
i see a crack in the end of vedio
Hahahaha nice
your welder probably doesnt have these settings
If i win lotto 350 it is.
