Converting QQ150 Torch to WP-9 (Need Assistance)

[arcs]

Hello, everyone, it's great to be here, I m a beginner with TIG and anything related to welding.
I bought a Chinese welder ws-250 TIG + ARC welding (2 in 1) for my hobby, it comes with a torch named QQ150, later I decided to buy more advanced TIG head which of course is WP-9FV Flexible with Valve, I bought all accessories for it, but to my surprise when I try to change the heads, they have different connections, my only sources of supply is Aliexpress and Ebay, this is my 3rd attempt to find an adapter but to no avail. Have ordered recently wp-9 repair connector but I will have to disturb the hose which is not desireable, I m just looking for a simple cheap adapter so I can swap the heads at my will.
The parameters that I found are as such.

QQ150 = M8x1 ???
Wp-9 = 3/8-24 UNF

I think to find the nut m8x1 and solder to the 3/8 adapter that I ordered, but I can't find, maybe I search wrong, or maybe you people have found something for sale, please let me know.
Here are the pics of QQ150 hose and WP-9 connections.
Thanks for the help and this place of discussion!

P.s. I found this on Ali but not sure if it's what I need.

Does it not have a switch on it not a valve

Does your hose also provide the electrical connection? Then a simple thread adaptor will work.

I cant remember exactly which threads are used for what, but there is a tig collet holder that shares the same thread, so can be brazed to an M8 x1 nut to make the adaptor.

nope that wont help you as it goes to NPT.

Yes it is also the power cable + hose for Argon, if you can look up for me a proper nut on Ali that would be great, thank you.

Im dont think there is an adaptor you can buy.

The thread on your torch will be 5/16" 24tpi UNF

tig torch connections

hello I need to know the connections for a tig torch 9 and 26. For tig 9/17 i think its a 3/8 unf but i dont know the threads. for tig 26 its a 5/8 unf i think. Can anyone tell me wich connection so i can buy a connection over here. Try to find it in air conditioning supply shop.

If you dont have a lathe, then to make one, you can use a wp9 collet body and braze or solder it to an m8x1 thread. A wp9 collet body is too small diameter to tap it directly.

Yes, have think to tap one adapter but I not have the needed tapping tools, also I don't have a lathe, but I do have bronze or brass rods the needed sizes, unfortunately this option is excluded.
I have order a reducer of female M8 x 1 and male 1/8 yesterday, I will use it to solder it to 3/8 adapter which I have buy recently, if it does not work I will have to disassemble the hose and add the 3/8 adapter in place of the M8x1 one.
Else I think the easiest option was to add a copper braided wire or some copper foil, around the male M8x1 and screw the WP-9 torch on it and then solder the connections.

Anyway I will post the end results later, thank you.

Forgot to link what I have order, this is the reducer (M8 x 1) and this is the repair adapter for wp-9 hose, maybe someone have similar issue, cause I searched and did not find similar to mine qq150 torch situation.

I made a mistake I bought female (M8 x 1) to male (BSP 1/4), not sure why can't edit reply but it would be useful, at least for 20 minutes.

So i received today the needed parts and have finished making the adapter, I had to solder them with hard solder that contain Pb in it, here are pictures of what I did.
Now remain to buy Argon and test, I plan to melt also precious metals, I have buy the plasma cutting hose and torch.
Hope it will help someone with similar issue.
P.s. I will ask Chinese to make such adapter made of copper, because the contact should be better with copper.
