Re: Current Limiting and Impedence

Malcolm,
What about non-magnetic stainless steel welding rods in 1/16" diameter? Is there some other reason not to use stainless steel? They are a lot more expensive than mild steel but they are also non-magnetic or do they need to be at least some magnetic? Thanks.
Paul
Think Positive
