    WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

    CAUTION When using a CV-250 power source with wire feed- ers, there will be a small spark if the electrode con- tacts the work or ground within several seconds after releasing the trigger. When used with some wire feeders with the electrical trigger interlock in the ON position, the arc might restart if the electrode touches the work or ground during these several seconds.

    FACTORY INSTALLED OPTIONS/ACCESSORIES There are no factory installed options/accessories on the CV-250. FIELD INSTALLED OPTIONS REMOTE VOLTAGE CONTROL (K857) The K857 consists of a control box with 25 feet (7.6 m) of four conductor cable. Installation of a K857 Remote Voltage Control in the CV-250 requires a K864 Remote Control Adapter.

    1. The fan motor has sealed bearings which require no service. 2. In extremely dusty locations, dirt may clog the air channels causing the welder to run hot with prema- ture tripping of thermal protection. Blow out the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on inter- nal parts.
