Abstract of the Disclosure An electric arc welder has a current-conducting means which can supply welding power to an arc along a first volt-ampere curve, has a second current-conducting means which can be paralleled with the first current-con- ducting means to supply welding power to that arc along a second and distinctly-different volt-ampere curve, has a voltage-sensing circuit which senses the arc voltage, and has a control circuit which automatically and virtually- instantaneously shifts the supplying of welding power from a point on the first volt-ampere curve to a point of essen- tially-equal potential on the second and distinctly-differ- ent volt ampere curYe when the voltage-sensing clrcuit senses that the arc voltage has fallen below a predeter- mined value. That control circuit will subsequently shift the supplying of welding power from a point on the second and distinctly-different volt-ampere curve to a point of essentially-equal potential on the first volt-ampsre curve when the voltage-sensing circuit senses that the arc volt- age has risen above that predetermined value. In this way, a welding wire or welding rod can be continually advanced toward a weld puddle in a work piece, and the welding power which is supplied along the second and dis- tinctly-different volt-ampere curve will transfer the tip of that welding wire or welding rod to that weld puddle without "shorting" and thereby extinguishing the arc.
