Arc welder purchase.

[John S]

Input capacity 14 Kw ?
Do you live close to a power station ?

It's actually OK for 3mm steel, look at the duty cycle - 10% that means flat out 250 amps you can only use it for 1 minute in 10.
You need to know the 75% duty cycle given you will be positioning, welding, then re-positioning, I'm guessing the 75% duty cycle will be as low as 110 amp which is what you want for 3mm.
Start checking duty cycles for these 120 amp welders and you will get a shock
