To-day I witnessed a demonstration on building up cast iron with a Ni 
spray.A torch is the method of delivery. A bottle of Ni (nickel)was 
screwed into this custom set-up.
11# of acetylene 20# oxy. The torch has a trigger, when pressed the
powder comes out with the flame. The torch tip looks like a welding tip 
with a O2 trigger on it.

The piece was one half of an old crank style blower. One of the ears was
broken off where the two half s screwed together. First the piece was 
heated up to about 400* F. Then this slick
torch started to do its thang. The end product is a brandy new shiny
tab. He wanted $ 500.00 for the set-up. I can post pics if you want to 
see the process. I thought it was rather pricey.
If I did lots of cast welding and happen to have 500 clams I'd have one.
