Advice on 240V Inverters

What output of amps can Inverter welders go to on a 240v supply?

"over here" I see Lincoln & Miller units IIRC about 250 amps.

Can you clarify what you actually want to know?

Do you mean what's the most powerful inverter welder you can run on 240v?

Or do you want to know what current supply you would need for an inverter welder on 240v?

Big enough wires, can do quite a lot!

If limited to the standard mains socket of 240v 13amp plug. I was curious of what an inverterter could burn in term of rod diam. For example When using my 160amp stick welder on 4mm rods I had to use a 30amp supply

I don't actually know what size rods an inverter can burn while using ONLY standard 240AC without blowing plug on a 13amp plug.

My 200 amp tig inverter will run 4mm 6013 rods all day long on a 13 amp supply.

I have run 200 amps in tig mode on aluminium and never blown a fuse

My 195 amp transformer mig will run 0.8mm wire flat out all day long on a 13 amp supply too.

My old parweld 180 stick welder would also run on 13 amps all day long with any rod i wanted as well as the 160 amp mig inverter I had, could run that flat out with no issues on mig or stick

I got my SIP stick welder in 1982. I don't know if that is relevant

welders have come a long way since 1982...realistically, ignoring the TIG completely, between my mig and stick welding i can weld from 0.8mm to 10mm+ on a 13amp supply and my welders arent expensive units either

I have a 250A single phase inverter stick welder.
I've measured it and it's enough close but goes over and below 250A not steady

400 amp output, 240v, 63 amp input. Look at drop down.........

Will depend on the quality of the electronics and efficiency of the inverter.
The duty cycle would be a good indicator of what it will do.

Another important thing to note is that there are also 240V Three phase machines.
I think no one asked if the op ask for either single or three phase units

Generally over here there's 3 phase (220 volt x 3 or 415 volt, but that depends on how the machine itself is wired internally I believe) or Single Phase termed as 240 volt, which is most homes.

Houses with 3 phase are rare in the UK....

Same here in Italy.
But common in Germany.
In the US I think three-phase is 240V
