There is nothing wrong with using ferrite core.
Being loosely wound isn't a problem unless you're trying for maximum turns.
Using plastic or tape insulated wire is OK too if the desired number of turns is achieved with the thicker insulation.
Using #10 wire at high amps and low volts will cause heating of the wire and reduced voltage and current at the electrode while the arc is active.
Using his core and the largest gauge wire that will allow the same number of turns through the core will give the same/similar inductance with less loss.
