2mm tungsten final grind with 1000 grit emery cloth.

What's good enough for hobby work?

2mm tungsten final grind with 400 grit emery cloth.

I just received my diamond grinding discs from ebay today: http://www.ebay.com/itm/6-Grit-60-to-3000-Diamond-Coated-Flat-Lap-Wheel-For-Grinding-Disc-Disk-Tool/253062599687?ssPageName=STRK%3AMEBIDX%3AIT&var=552133836250&_trksid=p2057872.m2749.l2649 http://www.ebay.com/itm/4-80-3000-Diamond-Co...

So I've been in contact with CK and this is their response to the discolored tungstens: I looked at our stock of T0207GL and there is some discoloration on the electrodes. I did some digging and it is actually an oxide layer. The surface oxide layer can be more aggressive in hot humid weather. I thi...

I've used a lot of .040" but never seen this, or have I heard of tungsten oxidizing (not that this means it doesn't) My .040" are looking fine and shiny, it's the .020" that is looking very different. Why are you choosing 1.5% Lan over 2% thoriated? If you're going use use lan tungst...

Since this thread is still going, I have another question. I received some CK Worldwide 0.5mm/0.020" 1.5% lanthanated tungstens today. They are all matte and almost black, not silver and shiny as the CK 1.0mm/0.040" 2% lanthanated tungstens I already had. The CK 0.5mm/0.020" thoriated...

I received the replacement unit today and the fitting looks perfect this time

Thanks, I have had some arc start issues which I thought were from tungsten issues, but it turns out not to be related to the grinding process. So I have been overly careful with the grinding even though I'm a hobbyist. I will use the same "wheel" for all my tungstens, and I will have cour...

Thanks!

Quick question! All the tungsten grinding videos tell you to dedicate a grinding wheel for tungstens to avoid contamination. But will different kind of tungstens be able to contaminate each other? Can I use the same grinding wheel for both lanthanated, ceriated, thoriated ect. without worrying about...

As mentioned, I emailed CK Worldwide and they have coordinated with Rapid Welding to get me a replacement unit. Unfortunately, Rapid Welding was out of stock with the flex head version, so they took a rigid head version and fitted a replacement flexi head, leaving the rigid head in the box for me as...

I have removed the solder, it did not feel like soft tin solder, it felt more like silver solder. I can't find any shop in my country that sells CK products, my machine supplier, which is local, haven't even heard about CK Worldwide and he has been a welder for 20 years. So it's not something we use...

This doesn't look right. I have a 20 series and all of the mating surfaces are a fine finish as I recall. I have not seen anything that has a raw casting finish for CGA fittings from any well known manufacturer. Personally, I would send the pics to CK and please let us know how it works out if you ...

Ah yes, gas valve on torch handle, that makes sense, the gas lines should hold up very well to the post-regulator pressure. Back cap on both sides is a great idea, thanks! The torch is brand new from Rapid Welding in UK. I can't tell if it's genuine, but it has a sticker label with CK Worldwide on t...

Hi, I just received a CK9 torch with the superflex cable, and the 3/8" BSP fitting has what looks like some solder splash on the rounded mating surface. Is this normal CK Worldwide quality control? I thought CK was top quality, and all the other CK parts I ordered was top notch, so I guess I wa...

While looking at ebay for these diamond coated discs, I see more 4" and 6" sizes than 5". Perhaps I could layer a 4" on top of a 6" with a 6" backing plate and then have a course grit on the 6" for crude grinding like a new tungsten or one I got dipped in the puddl...

clavius, thanks for the link, those discs could probably replace my current sanding paper solution as those are around $1.30 each and rather quickly wear out. I see those diamond coated discs are also available in 5" so they would fit my current setup with minor changes (they are 16mm arbor hol...

Hi, I have had my TIG welder for a good month now and I wanted something simple and inexpensive to grind my tungsten electrodes. So I came up with this. disc.jpg Its a piece of polycarbonate plate with a center hole for a carriage bolt, a turned aluminium piece with threads for the bolt and normal 1...

Hi Steve, thanks for the reply. So from what I can understand, you're saying just go with 1/16" filler wire even for material smaller than that? One of my primary purposes with TIG welding is fabrication of exhaust mufflers for small 2-stroke gasoline engines used in model airplanes. I was thin...

This thread is a great idea!

I'm also soon to be a hobby welder, so it's nice with a thread like this to learn from others that's just starting.

Which size tungsten and filler?

How many amps do you set on the machine?

Hello forum, I'm new here and haven't even got my first welding machine yet, but I'm trying to figure out what accessories to buy to get me started with aluminium TIG welding. My local aluminium sheet supplier seems to only stock the following sheet materials: EN AW-1050A, AI99,5 H14 EN AW 5754, AlM...
