Abstract
A method and apparatus for reducing spatter is disclosed. A welding gun, which can be an integrated part of a welding system, includes a device, such as a solenoid or motor and roller, to slow, stop or reverse the wire. The device is activated in response to feedback indicative of a short, a short that is about to form, or the imminent clearing of a short. The detection of the short, forming of a short, or clearing of a short is in response to feedback based on current and/or voltage. Output current can also be reduced.
