On an ordinary 15 amp plug (20 amp fuse) household wiring on a home only 8 years old with a transformer on the property, what level of performance could I expect out of the Smootharc Advance MIG machine 275amp? Would it be running at 80% capacity perhaps? My shed is 50metres from the power box but the cable is one size up that is the minimum requirement (perhaps only 4mm/sq and is underground. Is it worth upgrading the cable or will it run alright? Can it be run on a 8kva generator 7kva regular?
In such a situation I wouldn't expect the machine to be able to supply you with more than 210 amp at 20% duty cycle. The other concern would be possible voltage drops, the machine is design to function inside a ±15% voltage range (so 204 to 276) outside of these range the machine will refuse to function until the voltage come back within that range. Considering you have a transformer on or near the property this may not be a problem but I would still recommend that you double check that transfer is actually delivering this voltage range. Considering the drop in performance too, unless you are wanting the remote body style I would instead suggest the Advance 200C instead.
