Site Selection
• Position your Forney Easy Weld
™
20 P plasma cutting machine near a 120V electrical outlet.
• Choose a location with good air flow and ensure no dust, smoke or gas is present.
• Place the unit on a flat and stable surface.
• Make sure obstacles do not obstruct air flow by allowing 12 inches clearance around all openings of the
machine.
• Arrange an open space workspace of at least 15 feet (5m) near the machine.
• If the machine must be moved, always disconnect the INPUT POWER CABLE (3) from the electrical outlet and
gather the cables so as not to damage them.
Connect Input Power Cable
Before you make any electrical connection, make sure that the POWER SWITCH (2) is OFF and the electrical circuit
ratings meet those stated in the ratings label of your plasma cutting machine.
The main supply voltage should be within ±10% of the rated main supply voltage. Too low a supply voltage may
cause poor cutting performance. Too high a supply voltage will cause components to overheat and possibly fail. The
electrical outlet must be:
• Correctly installed, if necessary, by a qualified electrician;
• Correctly grounded (electrically) in accordance with national and local regulations;
• Connected to an electric circuit that is rated for sufficient amperage per the ratings label of your plasma cutting
machine.
• Check the electrical outlet for proper output voltage.
• Plug in the INPUT POWER CABLE (3) to a 120V 20A electrical outlet (with a 30A time-delay breaker).
• A 120V 15A electrical outlet (with a 20A time-delay breaker) can be used with supplied adapter at lower
output amperage settings.
CHECK LOCAL AND NATIONAL ELECTRICAL CODES TO BE SURE THE USE OF A 30A
BREAKER WITH A 20A ELECTRICAL OUTLET IS ALLOWABLE IN YOUR AREA.
If you are unsure of any of the above, have your outlet inspected by a qualified electrician before using the plasma
cutting machine.
NOTE:
• Periodically inspect INPUT POWER CABLE for any cracks or exposed wires. If it is not in good condition, have it
repaired by a Service Center.
• Do not cut off the grounding prong or alter the plug in any way. Only use the included adapter between the
welder’s INPUT POWER CABLE and the power source receptacle.
