WELDING CABLE CONNECTIONS

CABLE INSTALLATION AND CABLE SIZES

With the engine off, route the electrode and work cables through the strain relief bracket on the base and connect to the terminals located below the fuel tank mounting rail. (See size recommendations below.) For positive polarity, connect the electrode cable to the ter- minal marked Positive (+). For Negative polarity, con- nect the electrode cable to the Negative (-) terminal. These connections should be checked periodically and tightened if necessary.

•Loose connections will cause the output terminals to overheat. The terminals may eventually melt.

•Do not cross the welding cables at the output termi- nal connection. Keep the cables isolated and sepa- rate from one another.

When welding at a considerable distance from the welder, be sure you use ample size welding cables. Table A.1 lists recommended cable sizes and lengths for rated current and duty cycle. Length refers to the distance from the welder to the work and back to the welder. Cable diameters are increased for long cable lengths to reduce voltage drops.

Lincoln Electric offers a welding accessory kit with the properly specified welding cables. See the Accessories section of this manual for more information.
