Hello, I received electrodes marked with two colors and I am looking for information about them

[BillE.Dee]

Im not seeing a real distinguishable difference in the color but I'd treat them as red - 2% thoriated. Is that what you ordered??

[Piotr Pakula]

I got them from a welder, they are 1/8" how many amperes do they require?

[cj737]

They can accept any amount of amps you wish to throw at them. The benefit of using a thinner tungsten is that at lower amps, they can be more managebale. I’ve welded at 18 amps with a 1/8” before quite successfully. I had run out of the correct type in a smaller size and found only a 1/8” in my drawer. No drama…

[Piotr Pakula]

Ok, I still have parts for the burner that are larger than size 26, maybe someone will recognize what they fit, 3 current connectors and lower in the foil there are unpacked tungsten sleeves, they are thicker and longer than the standard ones, which lie between the electrodes on the right side

[cj737]

The “collets” on the left side are for a proprietary type of torch. Those in the middle are more traditional collets that can fit in standard 17/26 type torches.

There are many older types of welding machines that used unique torch types. And modern parts might not be interchangeable with them. Don’t worry, just use the type that fit and toss the others.

[Piotr Pakula]

I wanted to give them to someone because I don't need them, but I have no idea who or what they would be suitable for

[Arno]

Messer Griesheim is a very old german welding and cutting tech company that can trace it's origins back to 1898

They are still around and are a pretty big company that have different sub-companies (including trading in welding gasses) that make pretty much anything. Most of the stuff they make these days is big and very industrial (oribital welders, CNC oxy-acetylene cutters, etc.), but in the past they did make smaller machines.

They they go back so far there's a lot of welding machines out there that pre-date real standards like we have now.

If there's any numbers or marks stamped on the non-standard collets and holders you may be able to find out what machine they were made for, but it may well be that these are for specialised setups like old mechanised welding systems and not meant to be used in a normal torch anyway.

Bye, Arno.

What projects should you use the lens and jumbo nozzles for?

[Piotr Pakula]

The black one is a thread reduction on which the gray porcelain nozzles are screwed on, and also a whole box of metal nozzles, I don't know what it is either, maybe someone will recognize it

[Piotr Pakula]

These clamping sleeves are originally packed in Arno foil packaging
