Making sense of my welder specs

Hi guys,

I own Cigweld WeldSkill MicroArc 140 and its specs say:

STICK (MMAW) Welding Output, 40ºC, 10 min.

140A@15%, 25.6V

70A@60%, 22.8V

54A@100%, 22.2V

Now, it's 10A plug welder and here is where numbers do not line up for me. 140A*25.6V=3584W where our 10A GPOs are rated 2400W. 1.5 minute at such overage should well enough to trip the switchboard, yet it works :sad3:. Can anyone enlighten me how does it manage to pull so much power from the 10A GPO?

Thank you.
