Wait a minute...
I'm not sure I'm following you...
Do you mean that you put a gouging rod in a stinger, set the power source at low enough amperage to carry an arc but not blow through the sheet metal, and then feed in silicon bronze filler like you were tig welding, with no sheilding gas?
That sounds crazy!
Maybe I misunderstood..
But then again, I know I have not seen it all...
Please clarify

PS
For those of you who may be interested...
Switching to Pure Argon and fine tuning the parameters was the trick.
This process works exceptionally well for galvanized sheet metal.
I especially like the fact that almost no hazardous fume is generated.
