Lower left knob, set it to zero. Also, do not use green pure tungsten with inverter welding machine. Try one of your other tungsten's and sharpen it before using it. And clean the little blobs from the screen on your gas lens. We don't have the manual so we do not know if you need to jsut turn the pulse frequency to zero or if you have to turn it off another way. Check the manual or give us a link to the manual for your machine.Arthurbl wrote:Pulse frequency ?Oscar wrote:Turn. Pulse. Off.
Sounds good thanks I'll give it a shot.. I'll take a pic of the manualelectrode wrote:Lower left knob, set it to zero. Also, do not use green pure tungsten with inverter welding machine.

Yep no changes only adding filler it got me .. I took some filler that did that to me to work and going to try it on another tig machine to make sure it's not the fillerexnailpounder wrote:That's just weird. You can honestly run that nice clean bead with no filler and then have the goose crap one when you use filler? If your filler isn't badly contaminated then I have no idea.

The only thing that change when this all happens is when I was trying to weld behind a pipe that was hard to reach so I stuck the tungston out as far as I could but I couldn't get enough gas coverage so I gave up after that it won't weld right when I add filler I was also messing with the setting to try and get it to work . But I'm almost sure I got the settings how they used to be .. the filler I took to work is one that I tired using I just snipped the end off that I messed up .. I tried no gloves to ruel that out same thing .. it's the same pack of filler I was using .. I sure hope so I'm lost .. no I don't know that thanks for the information tho ..MosquitoMoto wrote:exnailpounder wrote:That did not work.

Read the whole thread. Yes, that latest bead is an improvement but still not great - lots of soot and as Ex said, the cleaning band is huge.
Now...the constant theme here is that adding filler is where it all goes wrong, yet you were very recently using the same filler and getting decent results.
Is this a fresh pack of filler, new to you, do you know its origins? Is there any chance that the same pack could contain a mix of rods?
Has anything changed? Are your gloves clean? IS there any way the filler could be getting contaminated between the pack and the welding job?
This is a toughie but I'm sure one of the wise ones here will crack it eventually.
BTW, that welder you have is very common (as I'm sure you know) and sold in every colour and 'brand' combination known to man. Quality variations aside, I have seen a guy on YouTube welding aluminium cans with it, so the potential is certainly there.
He was setting up his machine and was trying his setting out with my filler .. it was a test and it proved my filler is good even though that's a bad weldexnailpounder wrote:That did not work. That cleaning band is gigantic and that black soot and contamination is less but there is still a problem.
I have cleaned everything with acetone and brushed everything still the same thing someone please help me figure this out !!!!!cj737 wrote:Have you cleaned your filler wire???? Take some acetone and a clean shop paper towel, and wipe them down really well. Aluminum oxidizes immediately, and all your welds with filler show contamination, the only constant being the wire.
After you wipe down the wire, take a picture of the paper towel, and make sure the parts you're welding are super clean! A good clean, stainless brush, followed by Acetone. Then weld. Tight arc and put the wire in and out and run a bead.
No sadly it's not under warranty anymore .yea maybe I'll take it part and see if I can find anything that looks burnt .. I tried new filler and new metal all the same thing .. I'll try a new tank if that don't work I guess I'm just screwed thanks for the help tho !!electrode wrote:Is the welder under warranty? If so maybe contact the seller and see if you can return it for a new one. Maybe when your electrode was stuck out so far and you had a large gap between the tungsten and the piece you fried a capacitor or something. Seems like we are at a loss here. Did you try some new filler from a different source or even another type aluminum filler like 5356? Looks like a AC frequency problem or a gas or filler problem.
