Powertig 200DX fairly new TIG welder

Performance- whatever is causing the scorch marks on the tungsten, could that also be why I am having the slightly grey welds (if there isnt enough gas for the tungsten I doubt there is enough for the workpiece).

Yes you are right about the powertig penetrating more and being a little hotter than the dynasty as is evident by the penetration when viewed from the back side (I doubt my phone would capture it well enough).

Anyhow, with a fresh collet and tungsten and with varying the flow rate a good bit, what else can I try to remedy that situation? I am using a #7 cup already.......perhaps a different set of consumables altogether ?

I'd try using a number 5. Sometimes bigger isn't better. Go lower on your amps.There is a big difference in the weld you laid down on the dynasty and on the Everlast. Its about twice as hot from the looks of it.

performance- I will try that for sure, honestly with the dynasty I usually used the smallest cup I could find b/c I was doing tight corners, but I will try some smaller cups and report back.

I finally got the weld color to what I am used to (not grayed out)....I think it is just due to the extra gas coverage when doing a joint though, perhaps I need a bigger cup when just doing flat plate.......but now I have to get more gas, I am out again lol.

So I finally swapped parts between the two pedals I have and it works, yay......although I wonder if it should be adjusted at the potentiometer...it reads -20 and as you increase the pedal it eventually goes to zero, but until that time the arc is very erratic.......regardless the arc stabilizes on aluminum around 10 amp (according to the display) so I decided to run some superficial beads on .060 aluminum sheets and a energy drink can. Aside from the arc swirling around sometimes (probably due to me grinding tungsten on a bench grinder) it works surprisingly well on the low end. My beads would have been more consistent on the can except I couldn't hardly move the torch without hitting the shelving above me lol........anyhow thought someone might be interested
