Yes, they changed the number system again. The 4 number code has been on
the boxes for a number of years. Now the catalogs show only this 4 number
code so the old code is being fazed out. It's a shame 'cause the former
code gave heat range, thread size and length, electrode type and the last O
designates "spezial", ie custom Neandereered for a particular application.
BELIEVE THAT.

Note that Bosch shows the Platinum alturnative for most applications, but
in none of them is it spec. The Super is spec, and for very specific
reasons on this motor.
