• Do not lay material or tools on the INPUT POWER CABLE. The INPUT POWER CABLE may be damaged and

result in electrical shock.

• Keep the INPUT POWER CABLE away from heat sources, oils, solvents or sharp edges.

• Do not use this welder on a circuit with a Ground Fault Circuit Interrupter (GFCI) on it. GFCIs are tripped by

welding arcs and your welding operations will be interrupted regularly.

Using the 20 Amp – 15 Amp Plug Adapter

If a 20A outlet (with 30A circuit breaker) is not available, you can connect your 140 FC-i Forney Easy Weld

™

welder to 15A outlet (with a 20A breaker) using the plug adapter. When using the plug adapter, use lower power

settings on the machine to avoid frequent circuit breaker trips. At maximum settings, the machine will draw more

than 20 amps regularly.

Generators

This welder can be operated from an AC generator. Ensure that the generator can supply a minimum of 4,000

watts of continuous output. The generator must not have an auto-idle fuel saving feature or must have the option to

turn auto-idle off. The generator must run at full speed at all times while your welder is plugged into it or you risk

damaging your welder. Any other power draws on the generator or anything that reduces the generator RPM may

damage your welder.

Extension Cords

For optimum welder performance, an extension cord should not be used unless absolutely necessary. If necessary,

care must be taken in selecting an extension cord appropriate for use with your specific welder.

Select a properly grounded extension cord that will mate directly with the AC power source receptacle and the

welder INPUT POWER CABLE (9). Only use the included adapter between the welder’s INPUT POWER CABLE

and the extension cord. Make certain that the extension cord is properly wired and in good electrical condition.

Extension cords must fit the following wire size guidelines:

• #12 AWG or larger wire

• Do not use an extension cord over 25 ft. in length.

Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively ventilated. See the

“Safety Summary” for more details (pages 5-9).

FOR YOUR SAFETY, BEFORE CONNECTING THE POWER SOURCE TO THE LINE

CLOSELY FOLLOW THESE INSTRUCTIONS:

• An adequate two-pole breaker must be inserted before the main outlet. This breaker must be equipped with

time-delay fuses.

• When working in a confined space, the welder must be kept outside the welding area and the ground cable

should be fixed to the workpiece. Never work in a damp or wet confined space.

• Do not use damaged INPUT POWER CABLE (9) or welding cables.

• The welding gun should never be pointed at the operator or other people.

• The welder must never be operated without its panels attached. This could cause serious injury to the operator

and could damage the equipment.
