Overheard a welder say he never preheats cast iron and just uses nickel rod cold

Tried it on a cracked tractor manifold last week and it held up fine, but has anyone else seen this actually work long term or am I just lucky?

Bet on it cracking again down the road.

Ha! @troy_scott is just jealous, I've seen cold nickel rod hold on manifolds for YEARS without issue.
