Welding off the Lister

Yessir Bob, my little operation sees all kinds of small engine problems and lots of non working generators. My first question is always Did you run it out of fuel under load? To which they almost always answer, Uh no,, but would that hurt it? 😆 Sometines they are lucky and it takes out the regulator, other times it cooks windings, I think it depends on how fast it dies as it runs out of fuel? Anyway I quit allowing people to leave the burned out ones here as the junknpile grew out of hand,😆

FWIW as someone who has an off-grid property, and a few Lister, and who does quite a bit of welding . . . this is my opinion
(and as others have commented) the load of striking an arc, the possibility of damage, the lack of portability with the Lister, the value of the gen head you may burn out - taking all these things into consideration, about six years ago I paid $450 for a 9kVa Chinese petrol generator. It runs the welder easily, it's portable-ish. It is unfailingly reliable (although it does have an EPA-complicated carb design - thanks Uncle Sam) and it costs nothing to run for an hour here or there
I reckon that's a safer and better option. The other day I loaded up the Markon head on the Lister (doing something unrelated to this) and, listening to the engine note change and the revs "droop" a bit, I felt I was doing both the Lister and the Markon a dis-service
I have played with those little Chinese Honda-clone "Chonda" generators almost daily in my work for the last decade (I own six or eight personally, and we have another six or seven in the depot here) and I have a lot of respect for their cheapness and their ability to do a job. Hand on heart I can say I have never seen one "blow" up - although they will if abused, of course
They are much-derided as "Screamers" in some groups - but really they're just a machine to do a job. If you understand them and are comfortable with basic maintenance - then they are a good option. It's easy to move one around the place in the boot of the station wagon and, when it's where I want it, I park the wagon in front of it so it cuts out a chunk of the noise
You do need about 7/8000 watts for the welder to run effortlessly and for the generator to have a long life
Just my $0.02

Hi All
Bob
Hope all is well down in Taz....
Thanks for the encouraging noises, I'll drag some more kit up here and give it a go, I'm hoping to put a five speed gearbox in my 88" Land Rover next month and that'll involve knocking up new engine mounts as the later box is around 150mm longer, I should have bought a bigger truck!
Mike
That's a good shout, a quick scout around here and they seem a bit dear, still I'm going to go back to the UK at the end of the month, who knows what I can find at the Great Dorset Steam fair...
Cheers
Stef

Funny! I refer to my "Predator" 4k generator (Harbor Freight), that I use as emergency back-up when a Lister's down, as "The Little Screamer"!
