This equipment must only be used for welding operations in accordance with the limits indicated on the descriptive panel and/or in the user manual.
Safety instructions must be followed. In case of improper or unsafe use, the manufacturer cannot be held liable.
This equipment must be used and stored in a room free from dust, acid, flammable gas or any other corrosive agent. The same rules apply for
storage. Operate the machine in an open, or well-ventilated area.
Operating temperature:
Use between -10 and +40°C (+14 and +104°F).
Storage between -20 and +55°C (-4 and 131°F).
Air humidity:
Lower or equal to 50% at 40°C (104°F).
Lower or equal to 90% at 20°C (68°F).
Altitude: Up to 1000 meters above sea level (3280 feet).
INDIVIDUAL PROTECTION & OTHERS
Arc welding can be dangerous and can cause serious injury or even death.
Welding exposes the user to dangerous heat, arc rays, electromagnetic fields, risk of electric shock, noise and gas fumes. People wearing pacemakers
are advised to consult a doctor before using the welding machine.
To protect oneself as well as others, ensure the following safety precautions are taken:
In order to protect you from burns and radiations, wear clothing without turn-up or cuffs. These clothes must be insulating, dry,
fireproof, in good condition and cover the whole body.
Wear protective gloves which guarantee electrical and thermal insulation.
Use sufficient welding protective gear for the whole body: hood, gloves, jacket, trousers... (varies depending on the application/
operation). Protect the eyes during cleaning operations. Contact lenses are prohibited during use.
It may be necessary to install fireproof welding curtains to protect the area against arc rays, weld spatter and sparks.
Inform the people around the working area to never look at the arc nor the molten metal, and to wear protective clothes.
Ensure ear protection is worn by the operator if the work exceeds the authorised noise limit (the same applies to any person in the
welding area).
Keep hands, hair and clothes away from moving parts such as fans, and engines.
Never remove the safety covers from the cooling unit when the machine is plugged in. The manufacturer is not liable for any injury
or damage caused due to non-compliance with the safety precautions.
Parts that have just been welded will be hot and may cause burns when touched. When servicing the torch or electrode holder,
make sure that it is cold enough by waiting at least 10 minutes before doing so. When using a water-cooled torch, make sure that
the cooling unit is switched on to avoid any burns that could potentially be caused by the liquid.
It is important to secure the working area before leaving it to ensure protection of the goods and the safety of people.
WELDING FUMES AND GAS
The fumes, gases and dust issued by the welding are dangerous for the health. It is mandatory to ensure adequate ventilation
and/or extraction to keep fumes and gases away from the work area. A fresh air mask is recommended in cases in case of
insufficient ventilation in the workplace.
Check that the aspiration it is efficient by controlling compared safety standards.
Care must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding certain pieces of metal
containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to degrease the workpiece before welding.
Gas cylinders must be stored in an open or ventilated area. The cylinders must be in a vertical position secured to a support or trolley.
Do not weld in areas where grease or paint are stored.
