The OP says 10mm OD, are you guys talking about 10 mm bore?

Yes try it on a short length of hose then you will know if the wrench is man enough and can then replace either the long hose or the wrench. I have a feeling it will be a combination of both unimpressive wrench on a restrictive hose and regulator giving low torque.
The other way is a 230V electric impact wrench which are cheap or a good battery impact wrench which are expensive.

Yes, but he doesn't say bore or OD. 3/8 is near as dammit to 10mm (9.525 mm)

I think I would try a different gun. I have a cheap 1/2" and it's pretty hopeless. I got a lend of a Snap-On for a reluctant crankshaft bolt and the difference was amazing (same hoses).
My 1/2" air gun also won't look at undoing wheel nuts - I bought a 230V corded one from eBay for about 16 quid which is much more torquey.

Probably the gun. There was a post a few days ago where somebody had a similar problem and they took the gun apart and cleaned up / deburred the turbine part and it was better.
Well I just connected the gun to directly to the tank (@120PSI with no regulator in line) through 10m of 3/8 ID hose using 1/4 PCL XF connectors and it would not budge a single nut on my wheel. These nuts were recently off as I had changed the pads and discs so I know they are not seized.
looks like the gun surely?
Would a CP 734h do the job?

Wow, talk about getting upset. Its only a hose
OP has what he has, it will be cheaper and better in the long run to buy bigger bore hose, to run his cheap gun.
If as you are all saying 3/8" hose (as thats what he has not 10mm) then why it is not working?
A new hose with help with anything he wants to run, when he finds a new gun, that will too.
Back to my coffee
3/8 is 10mm, in air hose terms.
3/8 is good for 1/2 impact wrenches, over normal hose lengths (10-20 meters). Yes you can flow more through 1/2 but don't need it for most of the tools you want to run off a small compressor. The downside to having a hose that's considerably larger than necessary is increased weight and more cumbersome to use.
I've run impact wrenches off 8 and even 6mm hose on occasion when necessary and although certainly not ideal or recommended if the gun is half decent it'll cope.

Gun is at fault then.
As to the CP you mention I'd say the specs are about midway/lower side of midway and it ought to do things like wheelnuts.
Before parting with hard earned though I'd try to get some real world reviews of them, it's not a make I'm aware of using myself.
I run one of these, light, comfortable and powerful. Looks like there are some special deals around at the moment with free stuff

The problem is as soon as you pull the trigger ( his broom handle breaks
) no seriously, with the tank at 120 the air pressure drops to about or less than 90 you need the 150 to give it the kick up the rotor, the larger the hose the better obviously but 1/4 pcls are SOOOOO restrictiveany compressor will run any gun 'but for how long' thats the issue, I use a3/4 on a 25 ltr portable pressor sometimes, for just breaking hub nuts crank bolts free, but then change to the 1/2 to run them.
what I do is turn the pressure up to 150 and adjust the differential to minimum.
better pressure switches are the key that have a 1bar diff.

the angry jester guns http://www.angryjester.co.uk/product-category/impact-wrenches/ are good, and quite cheap I have one, but my milwakee beats it easy. I wouldnt mind one of the ultra compact ones.

I agree that pressure drops due to flow restrictions, and also that the standard PCL fittings are terrible - just changed all my setup to Euro at high cost.
But the fact is a 120 psi system is still adequate for decent impact wrenches to perform well. Give you example, I tried out a Bluepoint 1" impact before buying off a 120 psi compressor and a pretty long (15m ish?) 3/8 hose - and stripped the rear wheelnut on the tractor I was testing it on by tightening it up too much.
I also tested the 1/2 MG725 before buying, that compressor did 145/150 psi but only had a 1/4 hose with a 90 degree elbow, and two pcl fittings. The wrench still undid and tightened the test wheelnuts (same tractor rear wheel) with an equivalent force to me literally bouncing my full weight off a 5' pipe to undo them again.

I would never have thought a 3/8 hose would run a 1" gun I use at least 1/2 on my 3/4snap on

Also the start point of 120 is pretty useless when the pressors diff is 2bar so the tank is at 90ish to begin with, you end up running off air to get down to the switch on point,because at the gun you would be lucky to achieve 60psi, so to then try to undo a tight nut again and with a big tank, that could be 3-5mins ish before pressure is achieved.

HEHE also try blowing up truck tyres at 120 tank pressure it can take 10mins to get that last 5 psi in !!
