1. An arc welding apparatus comprising:
- a battery powered current source;
a rod holder coupled to the current source;
a duty cycle controller controlling the duty cycle of a pulsed current flowing from the current source and into the rod holder;
a pulse weld controller controlling the flow of the pulsed current to the rod holder and causing the pulsed current to turn on and off at a fixed tack weld frequency;
the tack weld frequency and duty cycle being independent of each other.
