Let me rephrase, most Pyrex manufactuers recommend they not be used for aluminum. Can you yes, I have but I want mine to last so I use the standard ceramic for aluminum. To each their own.

Interesting that you use Furick cups but shy away from using them on AC. Especially since all he does is use them, particularly on AC.

The larger ones he doesn’t so I assumed the #8 cups fit the same description. I guess I was mistaken.

That’s because there’s not really a needed application for a 12/16 cup with aluminum like there is for Ti or Stainless; which is the intended market for his Fupa, Moose and BBW.

Even so, you can use them for ally, but why would you? You just don’t need that kind of coverage.

I hear what you guys are saying!

I guess I will be needing both types of gas lenses after all, I just need be more selective so I don't have too many pieces to go through.
Right now I'll stick with the medium size gas lenses and just a couple of pieces of the jumbos to experiment on stainless steel..

Aluminium is most for me to start learning on it because I believe it will allow me to refine my technique.. and by "allow" I actually mean "force" me to because, well, Proficiency, right?
Titanium, I do see it a little bit more down the road but starting with the "basics" I believe aluminium might be good for it.

I will use my machine mostly on mild steel and stainless steel because that's what most people ever request it the most over here on the island..

I'm craving hours under the hood, It has been a long while since I've been able to really work on any type of welding..

Parts:
medium gas lenses collet bodies and collets 0.40", 1/16th, 3/32" and 1/8th
alumina cups 6, 7, 8, 9, 10 and 12
Pyrex cups 8, 10 and 12

Jumbo gas lenses collet bodies and collets 3/32" and 1/8"
alumina cups 6, 8, 10 and 12

What do you guys think?
Should I get a Jumbo gas lenses collet bodies and collets 1/16th while I'm at it as well?

Put your money in 3/32 collets the rest you will only use 10% of the time. Maybe 1/8" if you have a bigger machine.

For ally welding I use a 5 or 8, 3/32” for most of it. 1/8” tungsten when thickness demands.

Learn on mild steel. Get your basics right. Then go to ally. Then to stainless. Stainless is VERY TRICKY and for steel, I use an 8 or a 12. You don’t need the smaller lenses and tungsten did you have a quality machine. Save your money and drawer space. Buy a tungsten sharpener and a purge kit instead.

Very solid advice right here! Couldn’t agree more.

I agree with you! Fundamentals are very important to anyone first coming in to this line of work, I've been there!

I'm not an expert by any means. Carbon steels and stainless that's what I got my certifications on.
I went to school for it and got my 6G pipe (EN287-1 : 141+111) certification + a couple other ones..

Back to topic..
The smaller hardware is for those odd jobs with very very thin wall (sometimes under 1mm thickness) that 3/32"just wouldn't cut it.

You're giving me good ideas on where to start with my accessories hardware!
I like it!

Tungsten sharpener is on my bucket list!
Right now, I use attachment to a 4"angle grinder to sharpen along with one of those mini "pens" with a small chuck on it.
As for purging I mostly use aluminium tin foil and aluminium tape.. I also have a gas feeder from a gas stove like one of those on the barbecues with lots of tiny holes.



With this new welding machine that I bought, which it's still halfways across continental Europe, about 3 more weeks until it gets here!
Things take time to get here, it's not like I can drive to a welding supply store..there are none of those here on the island!
Argon bottle takes 1week minimum to ship it by boat and get a refill bottle!

Dream is to have my own welding business one day, (just far away from here, because I dream big) mostly towards non-industrial boat repair shops, custom stainless and alu jobs, motorcycle parts, etc etc..
I love fishing just as much as I love welding! Combine the two and I'm golden!

Just haven't had a decent opportunity that'll allow me to move on in to the welding business but I'm not loosing hope.
I need to step up my game so when that one opportunity comes up, I can grab it and hit the ground running!

Thanks guys!

I'd encourage you to watch this video:
https://www.youtube.com/watch?v=-L1Ugdt ... fz6Oat17Jt

Basically, if you can't use a 3/32" tungsten to weld very thin material, then you are doing something wrong ;) Aaron (the guy who makes those videos) has others that you might find very instructive on getting the most from your new machine (in terms of settings, results, and tungsten prep to achieve super precise welds) and they are also very well produced. Next to Jody, Aaron is by far my most watched channel for his pure creativity and outstanding results.

It is possible.. There are tricks like the one I just saw from Jody do with a scratch start inverter where he flicked the filler wire to arch the tip of the tungsten with the work piece.. Blew my mind!

I've been following Jody, Mr Tig and I've actually seen that video you shared

But it could've also been a limitation of my own previous now deceased machine..that I am now replacing..
It was a scratch start only 130amp, no pulse, no preflow, no post flow, no upslope, no downslope, just a knob for setting the working amperage, gas flow directly from the bottle flowmeter and that thumbscrew valve on the torch.
Minimal amps it had 10A on the manual but I believe it was more like 15A on that machine


One example was a local machinist, Trying to build up the face off the edge of a machined down to just under 1mm thin bevel out of a 3.5inch stainless pipe + several hours of work on it..
I remember this one clearly because I warned him it would most likely not work, and sure enough, as soon as I lit it up I go to push a little 309 filler and blew a hole.
Ended up cutting that piece of bevel off, welded a pie and he had to machine it again.. which I told him in the first place it would probably have to be this way!

Hello everyone!

I have some questions...

What's your take on the Stubby gas lenses versus the normal sized gas lenses versus the large diameter gas lenses (aka Jumbo)?

Pro's and Con's?


Data:
-The stubby gas lenses use the WP-9 style Gas lens aluminas and 17GL collet bodies for use on the WP-26.
-The WP-26 Gas lenses use the 54N style aluminas with 45V24~45V29 collet bodies.
-The WP-26 Large gas lenses use the 57N and 53N aluminas with the 45V0204, 45V116, 45V64, 995795, 45V63 Large collet bodies.

I have purchased all the parts to make a stubby gas lens kit but it's still on route in the mail...

I'm also thinking of getting either a normal sized gas lens kit or a large diameter gas lens kit..

Just can't find information if there is an increased performance between the stubby kit and the normal sized gas lenses..
I've only found ceramic cups for those up to size #8 ceramics I believe..

What about the Large diameter gas lenses, are they worth the investement? Are they that much better than the medium and stubby gas lenses?
As for the ceramics on the Large, I can find sizes up to #15..

Sorry for all those hard questions!
