Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can
explode. Treat them carefully.
• These welders use only inert or non-flammable gases for welding arc protection. It is important
to choose the appropriate gas for the type of welding being performed;
• Do not use gas from unidentified cylinders or damaged cylinders;
• Do not connect the cylinder directly to the welder, use a pressure regulator;
• Make sure the pressure regulator and the gauges function properly;
• Do not lubricate the regulator with oil or grease;
• Each regulator is designed for use with a specific gas. Make sure the regulator is designed for
the protective gas being used;
• Make sure that the cylinder is safely secured tightly to the welder with the chain provided.
• Never expose cylinders to excessive heat, sparks, slag or flame;
• Make sure that the gas hose is in good condition;
• Keep the gas hose away from the working area.
Be sure to locate the welder according to the following guidelines:
• In areas, free from moisture and dust;
• 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 that could restrict natural air flow for
cooling.
Since the inhalation of welding fumes can be harmful, ensure that the welding area is effectively
ventilated.
Before you make any electrical connection, check that supply voltage and frequency available
at site are those stated in the ratings label of your generator.
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 Power Source 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.
