SAFETY AND INSTALLATION

3.04 Location

Be sure to locate the welder according to the following guidelines:
• In areas, free from moisture and dust.
• Ambient temperature between 14°F (-10°C) to 104° F (40° C).
• 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 300mm (12") or more from walls or similar that could restrict natural air flow for
cooling
• The enclosure design of this power source meets the requirements of IP23S as outlined in EN 60529. This
provides adequate protection against solid objects (greater than 12mm), and direct protection from vertical
drops. Under no circumstances should the unit be operated or connected in a micro environment that will
exceed the stated conditions. For further information please refer to EN 60529.
• Precautions must be taken against the power source toppling over. The power source must be located on a
suitable horizontal surface in the upright position when in use.
Thermal Arc advises that this equipment be electrically connected by a qualified electrician.

3.05 Ventilation

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

3.06 Mains Supply Voltage Requirements

The Mains supply voltage should be within ± 15% of the rated mains 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 Welding Power Source must be:
• Correctly installed, if necessary, by a qualified electrician.
• Correctly earthed (electrically) in accordance with local regulations.
• Connected to the correct size power point and fuse as per the Specifications on page 3-2.
Any electrical work must be carried out by a qualified Electrical Tradesperson.
