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.

Before you make any electrical connection, make sure that the POWER SWITCH is OFF, power supply voltage and 

frequency available at site are those stated in the ratings label of your welder.
The main power supply voltage should be within ±10% of the rated main power supply voltage. Too low a power supply 

voltage may cause poor welding performance. Too high a power 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 national and local regulations;
•  Connected to an electric circuit that is rated for sufficient amperage per the ratings label of your welder.
If you are unsure of any of the above, have your outlet inspected by a qualified electrician before using the welder.

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 and do not use any adapters between the welder’s 

INPUT POWER CABLE and the power source receptacle.

•  Do not violently pull the INPUT POWER CABLE to disconnect it from power outlet.
•  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.
