Gas lens?

[Buggy Chief]

I understand that using a gas lens reduces consumption of Argon. Is this accomplished automatically, or can you dial your argon back from 7ish lpm?

It "uses" less because it puts out a more uniform argon blanket, which allows you to turn your flow down on your regulator. You can google them and find some pretty cool comparison pictures between the standard cup and gas lens.

One problem with a gas lens is that they are bigger than the normal cup. Makes it hard to use them in tight places

Even though they are bigger sometimes depending on the place you trying weld you can extend the tungsten out about and inch with a oversized cup. You can see it done here. http://www.weldingtipsandtricks.com/...eel-parts.html

Thanks for the information

Not really since you can hang the electrode out from the cup a lot further that without a gas lens.. I haven't used anything but a gas lens in the past 30 years.. They are dirt cheap now days and far Superior to the other way..

I don't understand what you mean. Are you saying you can stick the electrode out farther with or without a gas lens?

[CGCINC]

You can extend the electrode out more With a gas lens because of the better flow... This will help compensate for the size of the gas lens.

You can stick the electrode out farther with a gas lens since it directs argon out of the torch in a smooth straight column... gas lens on right><picture from CK Worldwide.

Yeah his post gave me the impression he was saying that you could stick it out farther with a regular collet body. I have stuck the electrode out over an inch to get into tight places before.

I have never seen anybody that has spent the 12 dollars for the small gas lens setup or 20 dollars for the large gas lens setup go back to the standard cups.

In the 20 series torch, the small gas lens is short and compact. The large gas lens is longer like the 18 series gas lens.

The 18 series gas lens (small and large) are about the same length as the standard cups. I run very large cups, and want the largest area of coverage. The last thing I need is to have someone at the other end of the shop open a door, and have a gust of wind ruin a chassis with an ugly weld that I have been working on for a month.

I posted pictures of a large 18 series gas lens, #12 cup and a short cup that will allow the tungsten to be pushed out 2 inches if needed. The short cup can be used for titanium as well.

Good tip!
Where do you buy those cups and lenses for $12 and $20?

thank you,

Good to see someone else who uses that sight. I subscribe to their videos to get my "fix" of welding every week.

A picture is worth a thousand words!

Unless Everlast sells them here ...ebay!

Unless Everlast sells them here ...ebay!

It's actually much cheaper... http://www.weldingcity.com/?subcats=...search&x=6&y=4
When you click on any of those parts you'll see a chart with what part numbers fit what or follow this link> http://www.weldingcity.com/tig-consu...llet-body.html

It's all very simple, the gas lens just replaces the regular collet body and you'll use the standard collets with them. Alumina cups for gas lenses screw on to the gas lens and use the same insulator that came with your torch.
If you have any questions just ask. Edit: Here's a nice poster from CK Worldwide to illustrate http://www.ckworldwide.com/CK_POSTER.pdf If you need a pdf reader to open it, I like free file viewer http://www.freefileviewer.com/ it's very small and safe... decline on all the add ons when you install it, works great.

I found Welding City and their graphic on eBay originally, but placed my order through their website.

i think im going to make a order for these for my wp9 and wp17 what size should i get, im still very new to the tigging so a overall good size would be best for me to start with?

now lets say your run 7 L/MIN what do you run with gas lenses?

On the large flood cups I run use about the same gas as the standard cups, the wp9 with the standard gas lens and a 7 or 8 cup will save about 2 L/MIN. On the wp17 I like the large gas lens with a 12 or short cup but you may like an 8 cup.
The large gas lens are harder to find for the 9/20 torches and are the most expensive of all gas lens, I paid 32 dollars for mine at the weld shop. Some gas lens take a special insulator and the large 9/20 takes a special collet. I could post some pics if needed.
