Strong Disagree.If you are welding really thick plates, you are better off with stick.
depends on supply 16amp/32 amp etc.
What are you trying to do ?What is the highest amount of amps I can get on a single phase welder?
Seen some welder which are both 240v and 3 phase so not quite sure if the max amps it says it does would mean I’d have to swap onto 3 phase to get that amperage

It makes a difference.What’s the difference

Would you mind explaining? im just interested in what the difference is since both are same amperageIt makes a difference.
A big difference.

No worries that’s totally fine :-) I have no information. I was just generally interested in the differencesI'm not writing a book just for you.
Give us some more information, and we will try to help guide you.
In terms of welding very little.What’s the difference between 400 amp on single phase vs 3 phase?
400A is 400A whichever/whatever its source might be.What’s the difference between 400 amp on single phase vs 3 phase?
This makes senseIn terms of welding very little.
At most a single phase machine might have a lower duty cycle (% of time it can weld Vs cooling down, when running at maximum power).
But practically:
1) Some parts of the welding machine will be designed slightly differently to account for the lower supply voltage (and significantly higher current draw).
2) The circuit supplying the machine also needs to be rated for a much higher current, which:
• requires substantially thicker (and more expensive per metre) cabling,
• will need the electrician installing it to put more thought into the overall design of your electrical supply (to do things like make sure you won't blow the main fuse on your supply if someone decides to boil the kettle and microwave their lunch in the canteen, whilst another person is welding).
So in practice:
› If a 3-phase supply is available it will almost always be a better option to power high-output welding plant,
and
› If a 3-phase supply isn't available, using a generator to run a 3-phase welder can often still be preferable and cost effective (depending on your electricity supply).
Single phase machines:I understand they can have higher amperage but a welder at 400 amp single phase vs 400 amp 3 phase. What difference does that make? Iv heard it’s more cost effective on 3 phase
