Abstract:
A system and method of starting a welding operation is provided where an electrode is advanced towards a work piece in a pulsed fashion and having a voltage level which will provide a first current when contact between the electrode and the work piece is made. After contact the electrode is retracted so that a welding arc is established and after the welding arc is established the current and wire feed speed is increased to a welding level.
