Site Selection

BE SURE TO LOCATE THE WELDER ACCORDING TO THE FOLLOWING GUIDELINES:
• In areas free from moisture and dust;
• In areas with ambient temperature between 30° to 90°F;
• In areas free from oil, steam and corrosive gases;
• In areas not subjected to abnormal vibration or shock;
• In areas not exposed to direct sunlight or rain;
• Place at a distance of 12" or more from walls or similar obstructions that could restrict
natural air flow for cooling.

Power Source Connection

Before you make any electrical connection, make sure that supply voltage and frequency available at
site are those stated in the ratings label of your welder.
The main supply voltage should be within ±10% of the rated main supply voltage. Too low a voltage
may cause poor welding performance. Too high a supply voltage will cause components to overheat
and possibly fail. The welder outlet must be:
• Correctly installed, if necessary, by a qualified electrician;
• Correctly grounded (electrically) in accordance with local regulations;
• Connected to the correct size electric circuit.
NOTE:
• Periodically inspect supply cable for any cracks or exposed wires. If it is not in good
condition, have it repaired by a Service Center.
• Do not violently pull the input power cable to disconnect it from supply outlet.
• Do not lay material or tools on the power supply cable. The cable may be damaged and
result in electrical shock.
• Keep the supply cable away from heat sources, oils, solvents or sharp edges.
• If you use an extension cord, keep it as straight as possible. For lengths up to 50 ft. use 12
AWG. For lengths up to 100 ft. use 10 AWG.

Ventilation

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