The wobble in the video concerns me.https://www.amazon.com/photos/shared...30TJzI2OBxR9HDI thought I read arcing is possible if the electrode connection at the torch isn't solid.I also ordered some wedge collets which are on the way.Any ideas?
Reply:I haven't done much tig, and I'm not familiar with that gas lens setup, but it looks like your collet is in the wrong way.  I've always put them in with the shoulder on the back side.  Of course, I could be seeing something that is not really the case....
Reply:That is correct the shoulder should be in the back, the back cap pushes if into the torch body to get tighter.  To remove or replace the tungsten you just loosen the back cap and pull it out the front of the torch.  If you notice the collet has a bevel on its tip and this is what tightens on the tungsten.DIY CNC Plasma table USB BOB Price THCHypertherm 65Everlast PowerTig 255 EXTMiler 180 Mig13" metal latheMill/ DrillECT, ECT,

Replytungsten wobbles a littleot of craziness out there
Reply:Maybe has to do with the domatrix that got ran off here by a couple punks couple years ago?
Reply:Sorry, it has been a long stupid day. I should have worded this different. Even with the tungsten securely in place, it wobbles slightly in the torch from side to side. Is this a function of the collet (ordered wedge collets) or the gas lens itself. There is a metal retaining ring that keeps the screen in place.  Oh, I think I see the misunderstanding. I think someone thought I had placed the collet in from the front somehow because of the  fixture on the front of this stubby gas lens......I assure that the collet is inside the torch...... please respond if you have used this type of gas pyrex lens to avoid confusion or misunderstanding. Cheers.Last edited by vdotmatrix; 11-28-2020 at 07:28 PM.
Reply:If the gas lens is fully tightened to the torch body and then the collet is shoved into the gas lens tightly there should be no movement. Is the gas lens body not tight in the torch head and loose or is the collet not grabbing the tungsten correctly. Are you sure your collet and collet body both match your tungsten size. Something isn't matching.If running 3/32" tungsten then the glass lens and collet both need to match. Sure you know this but double check the fit and sizes of each.Looks like a incorrect gas lens for a 17 but I know they do make some shorties I may not recognize but if the gas lens is wrong series that would be a problem but don't think it would fit so that may not be your problem at all.Last edited by danielplace; 11-28-2020 at 07:32 PM.

Reply:Originally Posted by vdotmatrixExactly, there should be no movement. I bought this gas stubby lens kit from Jody. I double checked collect, lens and tungsten straight away.....Tungsten is firmly sequestered in the torch by the back cap, it will not move in or out. My question to everyone is, do you see a slight wobble like that on your TIG torches, no right? Can the sleeve that is seen just past the screen get distorted to introduce wobble, do we ever see that? Could the tungsten be too short? I cut the short ones all the same length and have never felt this. I just bought the glass lens but that shouldn't effect the tungsten fit....I come here because you guys TIG weld a hell of a lot more than I do and see this stuff day in and day out. I appreciate your response(s).
Reply:So in the OP and video, the tungsten doesnt move much but, with that little bit of movement, can it cause arcing right?
Reply:if your using the collets with slices in the sides thats likely your problem. their designed to pinch down on the tungsten when the back cap pushes the collet into the tapered rear portion of the gas lens. but the pinching jaws of the collet get deformed and wont hold the tungsten. i recomend only genuine ck wedge collets and all your troubles will be gone

Reply:The gas lens I have are of a different design, as you can see in the attached images.  The opening of the collet body for the tungsten to come out is snug, and the collet will tighten around the tungsten as the back cap is tightened.  no wobble.

Reply:I find your use of the word “sequestered” to be somewhat confusing. Doesn’t seem like the right word to use but I’m probably wrong. In any case I think it just adds confusion when you’re trying to explain what the problem is. Anyway,Whatever type of Collet you are using,Make sure The shouldered edge fits into the back cap....Like mentioned above,When you tighten down on the back cap it puts pressure on the Collet and tightens up on the tungsten.  Are you sure the collet size matches the tungsten size?I use those slotted/wedge collets and they work just fine. Both types work just fine actually. I don’t have a pyrex cup handy for picturesBut here is a ceramic cup gas lense.  The tungsten is as tight as it can be.

Reply:Originally Posted by shovelonThose wedge collets are for water cooled WP20 style torches. Just put in the copper ones, tighten the back cap and move on. Eventually the kit chinee soft copper collet will fail and my suggestion is to source some high performance WeldTec made in USA collets made from Tellurium/copper alloy-P/N 10N24S(for aircooled stubby collet body). You can only source them from authorized weld supply distributors like your LWS. See part E from the parts sheet. http://tectorch.com/PDF/Updated_DS19...arts_sheet.pdf

Reply:I think most torches all fit the same, but none of mine fit “inside” the back cap like yours does. No matter, the shoulder fits in the back cap’s recess and “holds” the collet firmly in place until snugged. I looked at my long, medium and short caps and mine all fit the same....i will bet the wobble is a function or failure of my current  collet(s).  Originally Posted by John TI find your use of the word “sequestered” to be somewhat confusing.

Reply:Originally Posted by KelvinWait, what?I've lost collets, but I don't think I've ever worn one out...not sure HOW they would wear out...but maybe I'm doing it wrong again.
Reply:Something is likely not coming together right in your torch for some reason. Either the gas lens or the back cap isn't allowing the back cap to finish tightening all the way on the collet and it is bottoming out.

Reply:Originally Posted by John TIt should.
Reply:Maybe instead of all this exotic stuff (flex heads, swivel heads, gas lenses, etc etc etc) you should just try a vanilla torch with vanilla parts, so you'll at least recognize when things are right.Last edited by Kelvin; 12-02-2020 at 05:37 AM.
Reply:Originally Posted by vdotmatrixAs i mentioned before before folks got their aprons all bunched up over the word sequestered when i should have just just said that when the back cap is snugged down, the electrode is held in place (sequestered)
Reply:Originally Posted by MunkulThe word applies, just about, in terms of the Latin root  sequestrare "commit for safekeeping" but not by any of the modern meanings... but yeah, semantics.Good communication uses the most appropriate words for the situation... this was not one of them  I'm surprised you didn't substitute the word "wobbles" for "oscillates" or "flounders", if we're in the spirit of using obfuscating verbs... Anyway, I hope the new wedge collets sort the situation... a loose tungsten is not a good thing.
Reply:Originally Posted by vdotmatrixBUT, as in the title, it wobbles a little, as in the video, from side to side, ever so slightly. Just enough to imagine **** could be arcing, producing heat

Reply:Originally Posted by KelvinCopper is pretty freaking conductive. As long as the collet is touching the collet body and the tungsten is touching the collet, I don't think you're going to have "arcing" in the torch.As for you being able to move the tungsten in the torch with your finger or a pry bar, I wouldn't sweat it. It's not like you ever need to touch anything with the tungsten, anyway.Sounds like what we have here is a tempest in a tea pot ... or tempest in a torch head. But good luck. Did you ever get that mill scale removed?
Reply:I FINALLY rec'd the wedge collets!!!That tungsten is solid now!CHeers!
