itig 200T power factor

New member here looking at getting a power i-tig200t or similar. I'm just starting out so be gentle.

I have limited power in my shed. It can handle 25A at 240V (I'm in Australia) but it is a pretty long run from the house.
I would like to leave lights & ideally a fume extractor on while welding.

Does anyone know what power factor the 200t is rated at? I couldn't find it in the online manual or specs

The machine is just for learning at this point. I don't need to max it out but I probably will - just to see.
