Installation

Location

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.

Ventilation

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

Main Supply Voltage Requirements

Before you make any electrical connection, make sure the supply voltage and frequency available 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.
NOTES:
• 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 squash the supply cable with other machines. It could be damaged and cause electric
shock.
• Keep the supply cable away from heat sources, oils, solvents or sharp edges.
• In case you are using an extension cord, try to keep it straight, and untangled to avoid
overheating.
• Do not pull violently on the input power cable to disconnect it from supply outlet.

Safety Instructions

For your safety, before connecting the power source to the line, closely follow these instructions:
• An adequate two-pole switch must be inserted before the main outlet. This switch 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 or welding cables.
• The welding torch should never be pointed at the operator's or at other people's bodies.
• The welder must never be operated without its panels attached. This could cause serious
injury to the operator and could damage the equipment
