Hi all.
Picked this up yesterday cheap (free), cant find alot of info out there as far as specific to the hd300. So any help/ advice general opinions much apreciated. Also there is no plug on this can it be run off a 32amp 240v supply?. Cheers Dan.

55V × 300A = 16500W
16500W ÷ 240V = 68.75A
So if it is capable of single phase operation you would technically need a 125A plug, and might "get away with" a 63A...
But you many not even have a big enough cut-out fuse at your incomer to run that at full power as single phase, let alone worry about a plug.
With that kind of power demand it's very likely that it needs 415V (either split phase or three-phase), if that is the case, when you try to run it on 240V it will give a very low OCV which makes it near impossible to strike an arc.
If you open the top cover where the power lead goes in, and it has 4 terminals (Earth, L1/U/R, N, L2/V/S) then it's probably capable of running on either 240V or 415V, if it only has 3 terminals (Earth, L1/U/R, L2/V/S) it is probably 415V only.
Thankyou very much, very interesting this is what i have inside cover 4 posts.. 0, 240, 400 and 415 and an earth. So would i right in thinking that if i can get a 125a 240v supply to the garage this would be ok? Thanks again
I cant see myself needing to do any gouging so yeah i see your point, could well be an option thanks for the reply.

You're in luck!
If you already have a 32A socket, then it might be worth mounting one of these enclosures on the side with a 32A MCB permanently wired in between the welder and plug.
That way you will effectively prevent the welder drawing more current than safe, even if you forget subsequently.
If you don't have a socket, consider having a 63A socket installed on a circuit with as big of a supply as your electrician advises you can safely fit (I would assume 40A or 50A max).
If he wants to use low hydrogen rods like 7018, he also needs to run the equivalent calculations for 80V too.
If he can have a 50A circuit fitted, that would allow 150A an 80V OCV, which would leave a really capable welder.
Most older UK houses have a maximum of 60A, whilst newer houses or those with a recently upgraded supply will have 100A.
If he has a 100A supply, and doesn't have too many high power electric appliances (Shower, Cooker, Immersion Heater, Electric Heating) already, then an electrician may advise the could fit a socket that will do the full rated power.
Those old oil cooled sets are my absolute favourite stick welder's they run so smooth. I've got a 250amp cytringan.

you will get away with a 32 amp supply on 240 volt easily up to 180 amp weld current continuous. a 4.0mm cable will take 32 amp supply a 6/0mm even better in case of a long lead giving voltage drop . wire for single phase 0 neutral and 240 for the live . if its fed from a breaker it will need a 32 amp c type .domestic is generaly a b type and probably trip just on plugging it in
