Cable Installation

Install the welding cables to your WELDANPOWER 125 as follows. See Figure A.1 for the location of parts.

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. Normally, the electrode cable is connected to the positive (+) output termi- nal.

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 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.

Lincoln Electric offers a welding accessory kit with the

properly specified welding cables. See the Accessories section of this manual for more informa- tion.

MACHINE GROUNDING

Because the WELDANPOWER 125 cre- ates its own power from its gasoline- engine driven generator, you do not need to connect the machine frame to

an earth ground. However, for best protection against electrical shock, connect a heavy gauge wire (#8 AWG or larger) from the ground stud located on the bottom center of the output panel (see Figure A.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 WELDANPOWER 125 is mounted on a truck or a trailer, the machine generator ground stud MUST be securely connected to the metal frame of the vehicle. See Figure A.1.

The ground stud is marked with the symbol.

PLUGS AND HAND-HELD EQUIPMENT

For further protection against electric shock, any elec- trical equipment connected to the generator recepta- cles must use a three-blade, grounded type plug or an Underwriter’s Laboratories (UL) approved double insu- lation system with a two-blade plug. Lincoln offers an accessory plug kit that has the right type of plugs. See the Accessories section of this manual for details.

If you need ground fault protection for hand-held equipment, in-line ground fault current interrupter (GFCI) cord sets that meet UL and OSHA requirements are also available as an option. See the Accessories section of this manual for details.

AUXILIARY POWER RECEPTACLES

The control panel of the WELDANPOWER 125 features two auxiliary power receptacles:

•A 20 amp, 115 volt duplex (double outlet) receptacle (15 amp CSA).

•A 20 amp 230 volt simplex (single outlet) receptacle (15 amp CSA).

See Figure A.1.

CAUTION

The 20 amp, 115 volt duplex receptacle is “split phase.” Damage will result if you attempt to connect both sides of this receptacle in parallel to a load.

Through these receptacles the machine can supply up to 4,500 watts of single-phase AC power (3500 watts CSA). The machine output voltages meet UL stan- dards and fall within ± 10% of the rated voltage. The output frequency falls within ± 3% of rated frequency (60 Hz).
