A welding system includes an engine-driven welder generator that produces welding power. A welding torch receives the welding power and applies it to a stick electrode to initiate and maintain a welding arc. A parameter of the welding power, such as voltage, is monitored, such as to determine whether spikes occur during a short time after arc initiation. Based upon the monitored parameter, the engine speed is controlled. The engine speed may be increased or maintained at an elevated level if the monitored parameter indicates that particular types of electrode are being used, such as XX10 or cellulose electrodes.

Welder generator electrode based engine speed control

A welding system comprising a welding-type power source and a protective cover for the welding-type power source. The protective cover may be comprised of a synthetic fabric and a polymeric fluid barrier. The protective cover may have a member secured to the synthetic fabric to enable a user to grip the member to lift the cover from the welding-type power source. The protective cover may have a plurality of eyelets to enable the cover to be drawn against the welding-type power source. The protective cover may comprise a portion adapted to receive an exhaust pipe of the welding-type power source. The portion of the cover adapted to receive the exhaust pipe may comprise a heat-resistant synthetic fabric.
