TIG Torch Parts

[mcman56]

I bought a used TIG machine. It came with torch parts and I don't know what some of them are and wonder if they are for something else. See picture.
1. The parts across the top are what I have been learning with.
2. The parts below look like some kind of diffuser that should also work. Is that correct?
3. Mid right and bottom right look like a shorter version of the parts at the top. Is that correct? Is there an advantage or disadvantage?
4. There is a glass tube on the third row. Where does that fit in? What about the green o-ring and small round white collar?
5. Bottom left and next to left are parts that do not seem to match anything. Could they be for this torch?

I see picture is rotated here so please consider.

Top row: Is there a large white washer/spacer where the pink cup meets the torch handle?

2nd row: First 2 items area 'gas lens' and its matching cup - yes it should fit the same as the parts on the top row. Should give slightly better gas coverage / allow you to use slightly less gas flow. They will only suit one size of tungsten though, and may need the other style of collet (in the bag).

Glass cylinder / O-ring is a transparent cup. May or may not fit the gas lens above instead of the pink cup (o-ring goes over the gas lens and the glass sleeve presses over the top).

Far right: spare collets for clamping the tungsten. Again, they will only suit one size of tungsten.

The white spacers and all of the items on the bottom row look like plasma cutter consumables to me, and I don't think have anything to do with the TIG torch.

MisterG has it right the parts marked in blue are plasma cutter consumables. Green are standard tig torch consumables, the split collects and screw-in ends have different sized holes for different diameter tungstens. The yellow bits are gas lens fittings for tig.

Yes, the top row parts use a white washer/ spacer.

The glass cylinder with o ring will fit on the gas lens. Does either of these look correct? Does it matter if the white collar is in place? It does seem to protect the soft piece it snaps on to.

Top one for normal cups. The white collar acts as a seal against the cup. Might not be needed for the glass cup as the O-ring serves the same purpose. I’d be inclined to leave it in place anyway.

Parts in the bags I've numbered 1, 2 and 3 are all for a Plasma Cutter Torch

And the stuiff to the right of number 1 are collets for a 9 or 20 series torch.
It looks like the stuff above number 2 and 3 is a stubby setup, that enables you to fit 9/20 series ceramics, instead of the much bulkier 18/26 stuff on the top row.
