Gas Lens Assembly

admin

would someone kindly post pictures of a -17 or -18 torch head assembled with a gas lense , maybe partially disassembled as well.I am looking at the stuff i bought for mine and after putting it together it looks a lot different than what i remember the ones at work were like, they were-26 i think, not sure.seems to be an awfull lot of length sticking out the working side.i will post some pictures when i get home, just seems to bugging the bejesus out of me at work and i cant find any good pictures on the web anywhereother than the  part-o-gram at weldcraft , but no assembled pictures.

Reply:Here's some picts of my WP-17 with and without the gas lens. Note the collets are the same. It's only the cups and the collar? that are different.Std cup and parts.std cup parts (top) vs gas lens parts on bottom.Gas lens assembledGas lens disassembled.The cup on the gun in the 1st pict and the gas lens have aproximately the same opening size. I only have the one size on the gas lens. BTW I got my lens last thursday so your timing is good.Hope this helps.Last edited by DSW; 04-15-2008 at 03:12 PM.
Reply:i seem to have this extra gasket that looks like it goes between the cup and the white silicone piece that is attached to the welder. see attached.tis item number 4.looks like from your pics that i can get by without this ?

Reply:Man!That air cooled stuff is huge compaired to watercooled stuff.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:i have both a -17 and a -18 torch ( 18 is WC) and they ar eboth about the same,  are there smaller ones ?insert thoughtful quote from someone else2000 Thermal Arc 300GTSW 3.5 hours1946 Monarch 20 x 54 Lathe1998 Supermax 10x54 Mill2004 Haco Atlantic 1/2" Capacity Lasernot mine but i get to play with it

Reply:Items 4, 7 and 10 are the insulators/gaskets to suit their respective collet bodies (standard/large gas lens and regular collet body). Just a snap fit on the torch headThere's many torches that are smaller than a 17/18. 9 (air cooled) and 20 (w/cooled) are the next size down. Go smaller than a 20 (or air cooled below a 17) and the amperage ratings start limiting their uses- especially for AC
Reply:The gas lens is not really made to go on a aircooled torch.It is made for the water cooled WP-20.You can double check if you want but that has been my understanding.The WP-20 is rated 0-140 amps. The MOST commonly used size.Last edited by Donald Branscom; 04-15-2008 at 06:11 PM.

Reply:hmm.. I use a water cooled CK-20 with gas lens with a rating of 200 or 250 amps, I forget which.  It's more torch than I need for my 185-amp Thermal Arc at least, but it's still small and light weight.  I've never used an air cooled torch with one, but I don't see why a gas lens can't be used on an air cooled torch.  All the lens does is direct the gas over the weld.  The torch cooling happens up-stream of the gas lens/cup parts so I don't see what affect that would have on cooling.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:Air cooled torches (17&26) rely on the copper to disapate the heat build up.  JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases.  There all here. :

Reply:Wino It was my understanding that the gas lens would allow you to extend the tungsun farther to reach corners and such, while still maintaining gas coverage. I have noticed this at school with the water cooled torch, Actually the instructor showed this to me when I had the tungstun to short to see the arc well doing vertical up. Gas flow was left the same as with the standard setup 30cfh. I could definately keep the tungstun out farther (insanely far, he demonstrated this with about 1" of tungstun past the cup, no problems) with the gas lens and still not have porosity from poor gas coverage.

Reply:Wino Ok I see it now.Thanks. I was not trying to put you down. I'm still relatively new to the tig thing and trying to understand as much as posible and why.
