Can anyone suggest a suitable dummy load for this purpose? Needs to be

there's any intermittent breakdown in output (which I suspect there
may be with these newer inverter welding sets).


400mm of 2mm diameter stainless steel rod will give you 0.1 ohm.
Stick it in a bucket of cold water and it should be good for a few minutes.

I'm glad someone did the sum, I was thinking much the same myself (but
with steel: hadn't thought of using stainless).
