What would be the best single phase welder out there to buy for welding up to 10-12mm plate don’t have the power to get a 3-phase welder
I've got a 330a oxford and it pulls about 41 amps iirc at full load. Not that I've ever actually wound it up that high. Need to upgrade the workshop power supply first.Make sure you’ve got the power to run something that size, you’ll need a 63a supply and socket for that!
There was a long held school of thought, not without merit, that said a 3 phase welder would be smoother than the same on single phase, as the three balanced phases required less smoothing capacitors than a single 50hz spike of single phase.Best I used was a late 90's miller. Fantastic welder, other guys didnt like it because it was single phase, they NEEDED 3 phase. Same output though but they did not seem to understand that, i think it was a bit like the guy with the car with the longest bonnet scenario.
If 3 phase is available, 3 phase would be my choice every time . Sorry but I go along with the other guys choice, longest car bonnets got nothing to do with it.Best I used was a late 90's miller.

All new supplies in certain distribution areas are now three phase If you want it or not, and have been for the last year or so. I have recently had to connect a large house split into four single bedroom bedsits - each single bedroom bed sit had to have it’s own dedicated three phase supply from the mains. Even if the substation is only single phase we still have to put three phase service cable in.Worth asking the electricity board for a quote for bringing in 3 phase from the road. Someone I know got a quote, £1500 for a big 65 amp cable through a brand new duct. Not actually that bad if you need it. He needed a new supply anyway as the old overhead one is shot and needed replacing
I imagine that domestic electrical loads are expected to increase substantially in the future due to all the planned decarbonisation. Much increased use of electric cars and heat pumps etc. So I suppose its sensible futureproofing.All new supplies in certain distribution areas are now three phase If you want it or not, and have been for the last year or so.
