1.The gasoline engine must be OFF to install weld- ing cables.
2.Remove the 1/2 - 13 flanged nuts from the output terminals.
3.Connect the electrode holder and work cables to the weld output terminals. You can connect either cable to either terminal, since the POWER- ARC 4000 provides AC weld current.
4.Tighten the flanged nuts securely.
5.Be certain that the metal piece you are welding (the “work”) is securely connected to the work clamp and cable.
6.Check and tighten the connections periodically.
CAUTION
•Loose connections will cause the output termi- nals to overheat. The terminals may eventually melt.
•Do not cross the welding cables at the output terminal connection. Keep the cables isolated and separate from one another.
Lincoln Electric offers a welding accessory kit with the properly specified welding cables. See the ACCESSORIES section of this manual for more infor- mation.
