Advanceable Electrode
The SR-45i torch uses a patented advanceable electrode PN 770015. This means
on an average, an electrode can be used four different times. The length of time a
particular electrode can be used is determined by the depth of the crater that is
formed in the electrode material. Typically, the electrode should be advanced
after an hour of use, which will eliminate the copper electrode casing from being
eroded.
Using the electrode advancing tool provided in the spare parts kit, the electrode
should be pushed out of the copper casing a distance equal to the depth of the
crater. Then, while still in the electrode tool, the cratered electrode material
should be ground away until it is flush with the original copper casing. This can
be accomplished by using a common bench grinder. Care should be taken so that
none of the copper material is removed in the grinding process.
Note that a non-advanceable electrode PN 770017 is available.
