WARNING - SAFETY RULES
GENERAL INSTRUCTIONS
Read and understand the following safety instructions before use. Any modification or updates that are not specified in the
instructions manual should not be undertaken. Please store this manual safely.
The manufacturer is not liable for any injury or damage due to a non-compliance with the instructions featured in this manual.
In the event of problems or uncertainties, please consult a qualified person to handle the installation properly. The instructions cover the material in
the condition it was delivered. It is the responsibility of the user to analyse the risks taken when not following the instructions published by CHIEF.
ENVIRONMENT
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. 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 m above sea level (3280 feet).
INDIVIDUAL PROTECTION & OTHERS
Resistance welding can be dangerous and cause serious injuries or even death. It needs to be used by a qualified technician with training relevant
to the machine.
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 others against arc rays, weld spatters and sparks. .
Ask people around the working area to look away from at the arc or the molten metal, and to wear protective clothing.
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 mobile parts at a distance (fan, electrodes...) from hands, hair and clothing .
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. During maintenance work on the torch or the
electrode holder, you should make sure it's cold enough and wait at least 10 minutes before any intervention. When using a water-
cooled torch, make sure that the cooling unit is switched on to avoid any burns 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 GASES
Fumes, gas and dust produced during welding are hazardous to health. It is mandatory to ensure adequate ventilation and/
or extraction to keep fumes and gas away from the work area. Using an air fed welding helmet is recommended in case of
insufficient ventilation in the workplace.
Check that the air supply is effective by referring to the recommended safety regulations.
Precautions 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. They must be stored vertically and held by a support or trolley to limit the risk of fall. Do
not weld in areas where grease or paint are stored.
