The thought has crossed my mind...and the magnetohydrodynamic effect of
the plasma column from the torch with stray magnetic field.
I haven't yet had the opportunity to recheck the experimental
conditions.  As to the possibility of carbon/composition resistors,
I can say that the resistors I used shed their paint coat when touched
 after firing, and revealed the helical surface track which I associate
with  metal/oxide style resistors.
