A method and apparatus for initiating a welding arc includes a controller coupled to a power circuit for enabling the power circuit a predetermined time after an arc starter circuit has applied an arc starting signal at the power output of a welding device. The apparatus further includes a protective gas source for providing a protective gas, such as argon or helium, to the welding site. The arc starting signal ionizes the gas to aid in initiating the welding arc.
