MACHINE GROUNDING

Because the RANGER 300 creates its own power from its diesel-engine driven generator, and if the machine is not connected to premises wiring (home, shop, etc.), you do not need to connect the machine frame to an earth ground. However, for best protec-

tion against electrical shock, connect a heavy gauge wire (#8 AWG or larger) from the ground stud located on the bottom of the output panel (See Figure B.1) to a suitable earth ground such as a metal pipe driven into the ground.

WARNING

Do not ground the machine to a pipe that carries explosive or combustible material.

------------------------------------------------------------------------

When the Ranger 300 is mounted on a truck or a trail- er, the machine generator ground stud MUST be securely connected to the metal frame of the vehicle. See Figure B.1. The ground stud is marked with the ground symbol.

If the RANGER 300 is connected to premises wiring such as a home or shop, it must be properly connect- ed to the system earth ground.

WELDING CABLE CONNECTIONS

CABLE SIZE AND LENGTH

Be sure to use welding cables that are large enough. The correct size and length becomes especially important when you are welding at a distance from the welder.

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 infor- mation.

CABLE INSTALLATION

Install the welding cables to your RANGER 300 as fol- lows. See Figure B.1 for location of parts.

1.The diesel engine must be OFF to install welding cables.

2.Remove the flanged nuts from the output terminals.

3.Connect the electrode holder and work cables to the weld output terminals. The terminals are identi- fied on the case front.

4.Tighten the flanged nuts securely.

5.Be certain that the metal piece you are welding (the “work”) is properly connected to the work clamp and cable.

6.Check and tighten the connections periodically.

CAUTION

•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.
