Might be suffering volt drop if the wiring isn't up to scratch.
Cut down nailI run mine through a 13a plug with a, erm, slightly bigger fuse in it . Never trips the rcd though. I’d try try a a different rcd if you’ve got one.
could work but if its tripping at half power its surely better to just get a 32a b/c type mcb and some 4mm cable? otherwise the other half of the welder is pretty pointlessTry a type D trip. It’s not really cricket but they trip at 10-20xfull load current whereas the type C is 5-10. They absorb the spikes better (rather they don’t trip as easily with spikes) than a type C but should still save a life.
I like to refer to them as a “Noncompliant Amperage Integrated limiting System” or “nails” for short.Cut down nail
It may be possible even on a 4 pin socket. You must consult a competent electricianIs it possible to run a single phase off the 3 phase socket?
it is not. no neutral on 4 pin.It may be possible even on a 4 pin socket. You must consult a competent electrician
You are right.thats 4 pin 3 phase so no good, and its only 16A anyway, (guessing its the one labelled compressor?)
best bet just get a C32 MCB, some 4mm t+e, and a 32A socket, and get an electrician to fit it.

Thankyou yes sounds like I’ll have to get electrician in the new yearthats 4 pin 3 phase so no good, and its only 16A anyway, (guessing its the one labelled compressor?)

This has always worked for me!Try a type D trip. It’s not really cricket but they trip at 10-20xfull load current whereas the type C is 5-10. They absorb the spikes better (rather they don’t trip as easily with spikes) than a type C but should still save a life.
If you note I posted that it needs a competent electrician , without a close knowledge of the machine I cannot say if it could run off a 3 phase supply, but trust me many older machines can and did, as they are not specific about voltage. A lot of later machines only actually need the neutral to run the motor drive for the wire. Obviously if it is one of these it must have the neutralit is not. no neutral on 4 pin.
edit: @Exfarmer you see below it says 3P + earth, on 5 pin it would say 3P + N + earth
Welder set at 130 amps is more than adequate for 4mm rods to get good penetration and 90 for 3.25 rods , never had any problems110 cte is safer, from a genset it wont be cte anyway so not much safer. 110 is not compulsory on construction sites any more since the advent of rcds. Can use 240 with an rcd instead. You should be using a lot more than 140a on 4mm rods or you won't be getting any penetration.
i wouldnt really say having a 110 outlet on a generator is an advantage, if you have 110 tools then you will have a transformer anyway, which will give you proper 110 CTE, and if you plug the transformer into the generator it will be able to produce significantly more power than if running straight from the 110v socket on the genny, as well as being CTE. this is why i always use a transformer on the genny rather than the 110v socket
Should be 115-165 on 3.2, 150-220 on 4.0 (assuming you are using standard 7018) 7018 is the only one that will give you any hope of getting penetration without cleaning but will still make it weaker, especially if you aren't even burning the rods extra hot to get through the crap, which you definitely aren't if you are running 4.0 at 140. I usually run 130 on 3.2 as my default setting then tweak from there.Welder set at 130 amps is more than adequate for 4mm rods to get good penetration and 90 for 3.25 rods , never had any problems
