[TheForge] Welding flux?

[Jerry Frost]

I was in the local welding supply today, working up a material/price 
list for a youngster who wants to weld up the edges of his Trenton. So, 
while I was wandering around I noticed a product that drew my eye, I 
read the label and ingredients.

Petterson #2 High Heat Flux. The can says it's for brazing, bronzing, 
etc. cast iron, steel, SS; torch welding, brass, bronze, etc. It's a dry 
powder flux and the claim is it melts low temp, works on greasy, rusty 
and dirty, it cleans, deoxidizes and floats scale off and is no more 
toxic than hot borax. The usual, don't get it in your eyes, breath it or 
eat it, may be a skin irritant. It's boric acid, borax and iron.

Here in Wasilla a 1lb. can is $23.00+tax. I'm thinking it just might be 
worth experimenting with forge welding. Seems like the same ingredient 
list as most forge welding fluxes.

Anyone have any experience with Petterson fluxes in the forge? There are 
a few.
