If you have read some of the articles on this site
(firing systems ,
electrical
igniters ) , you might know that if you use
electrical firing systems, it is much, much cheaper to make your own
electrical igniters than to buy them.
Listed below are some suggested high resistance
wires for use in making your own igniters. As a rule of thumb, all
"igniter wires" should have a resistance
of 650-875 (higher is better) ohms/cmf and have a melting point 1100-1500° C.
