If using TIG rods, you must determine
whether the air hardening tool steel is in the "A" series or "D" series. You
must use a different
type TIG rod for each series. For type D2 tool steels, it is also important
to know whether steel
is in the annealed or hardened condition. A different TIG rod is required for
each type as follows: Tool
