As applied to welding machines, a welding power source which will produce a relatively small change in voltage when the amperage is changed substantially. Used mostly for welding with solid or flux cored electrodes.
Welding Tech
An arc welding power source with a volt-ampere output characteristic that produces a small welding current change from a large arc voltage change.
As applied to welding machines, a welding power source which will produce a relatively small change in amperage despite changes in voltage caused by a varying arc length Used mostly for welding with coated electrodes.
A material which has a relatively large number of loosely bonded electrons which may move freely when voltage (electrical pressure) is applied. Metals are good conductors.
The resistance of a material to a force which is tending to deform or fail it by crushing
