Some fine candidates for natural selection there. So many things wrong with that setup that it's hard to know where to start.
If you are reckless enough to take the risk of using suicide leads to connect two generators, then I don't understand why you just don't knock up one of the good old converter leads with a 10A male and a 15A female plug and plug it into your existing GPO. Frowned upon as they rightly are, you will be 100's of times safer using one of them compared to any of the setups shown in those two videos. Russian Roulette is what it is, except five chambers are loaded and only one empty. If you must persist with this idiocy, please at least ensure that you have a good earth stake connected to both your generators unlike the two numpties in the Youtube clips.
I don't particularly care if you get an electric shock as it will be entirely the result of choices you made, but what if someone else is the innocent victim?
Sorry or I didn't think will hold little sway when you front up in court.

I triedlooking into bigger inverter generators last night i kind of don't wanna sped over 1k or there abouts 1k doesnt really buy u much tho a portable (carry type) inverter 3.5kw cost $700'ish but it may only do 70amps i need a bigger kw geni for that innitial 20amp spike of lighting up
I looked at the noisey generators but they would be far to loud 105db, running two portables would be ideal but 1k doesnt get u much in terms of linkable inverter generators
Sussed out honda's which can be linked but my 1k would be gobbled up by a single 2.2kw machine
I can andhave been to date running the filed down extension lead pin but i am worring about a house fire i'm renting and dont need the problems with the power point melting and burning down the laundry or house

Interesting discussion.
I think some small generators designed to be paralleled actually send DC across the interlink cable, which makes load sharing easier (no AC sync required). Only one generator does the DC to AC inversion to supply the load.
Personally I'd never try to couple two units that are not designed for it, I'm not lucky enough to get away with it.
Question.
Do you really need an Inverter type generator ?
Older non inverter types are about half the price, (or twice the power output for the same money) and since you're a welder you could modify the exhaust by adding a second muffler to the first

Com VC i was going to run a RCD but not sure if they can handle the 20-28amp spike
Since i cant afford any small portable models without spending 3k i'm nowlooking at portable diesel silenced generators this one inparticular is local to me
https://www.edisons.com.au/84kw-max-...abbed_contents
But its not clear if i can pull 6000watts from a single outlet

There are many RCD’s that will handle that sort of load, they do not trip on current flow they trip on imbalance.
The generator is a three phase generator, meaning only one third of the load can come from any one phase.
And no you cannot connect the phases together because the AC on each phase is out of sync with the others.

Bugger! Looks like its a very loud generator or i could use two of these for 7000w/9000w for innitial draw but its $500 over budget

A bit of a spark in the smoke.. done abit of looking around and the mig welder i really want is a kemppi evoarc 170 mig, i just looked up on the kemppi aus web site and that particular welder can be used with as little as a 4.2kw generator
So do i sink $1900 on a kemppi mig and buy a new or second hand generator than sell my unimig razor 200 mig and unimig arc 180 to balance out the purchase?
I have had the unimig razor listed for sale and i am getting a little bit of interest in it but no sale yet
So basically i will be upgrading my mig to top of the range, dropping off the stick welder and going mobile

Yep this was what I was going to suggest. Will allow you plug a 15amp device in and if you are not maxing the welder out at the upper end it shouldn't trip, if it trips its done its job of protecting the fixed 10amp circuit wiring.
I would have guess and also say that I doubt the full board generator is able to maintain a pure 50hz sine wave as become maxed out.
I've using one of these to run a unimig 205 on mig when I wanted to weld something in my backyard that was too far away from my 15amp outlet.
