• Turn off the welder when it is not in use.
Important Information about Radio Electromagnetic Compatibility
• Extra precautions for Electromagnetic Compatibility may be required when this Welding Power
Source is used in a domestic situation.
• It is the user’s responsibility to install and use the equipment properly in accordance with the
instructions issued by the manufacturer. If electromagnetic disturbances are detected then it shall be
the responsibility of the user of the equipment to resolve the situation with the following guidelines.
Precautions to consider in the surrounding area that may cause/be affected by electromagnetic
disturbances
• Other supply cables or signal cables in close proximity to the welding equipment;
• Radio and television transmitters and receivers;
• Computer or electronic equipment;
• Personal medical devices (pacemakers and hearing aids).
Methods of reducing electromagnetic disturbances
• If interference occurs when the equipment is connected to the mains power supply in a residential
(domestic) low voltage power network, an electromagnetic filter may be required.
• The Welding cables should not be modified and kept as short as possible.
• Nearby cables and equipment may need to be moved or shielded.
Fumes
• Toxic gases are given off during the welding process, which may collect in the welding area if the
ventilation is poor. Be alert at all times to the possibility of fume build-up.
• Provide adequate ventilation or a means for removal of the welding fumes produced (forced
circulation using a blower or fan).In small or confined areas use a fume extractor.
Glare
• The electric arc generated by the process gives direct heat and ultraviolet radiation. It is essential
that the eyes of the operator and bystanders are protected from the glare during welding.
• ALWAYS USE A FACESHIELD OR WELDING HELMET FITTED WITH THE CORRECT GLASS FILTER.
Position and Handling
• Position the welding machine on a horizontal surface that is able to support the weight: otherwise
(e.g. inclined or uneven floors etc.) there is danger of overturning.
• The welder MUST NOT be supported by the operator (e.g using belts).
The operator MUST NOT BE ALLOWED to weld in raised positions unless safety platforms are used.
• Do not weld materials in overhead positions.
Heat
• It is desirable that welding gloves are worn whilst welding. They will protect the hands from ultra-
violet radiation and direct heat of the arc.
Dress
• In addition to face shield, welding gloves and overalls, other types of protective clothing should be
worn when welding. Additional protective clothing such as a leather apron, sock protectors and a hat
