THERMAL PROTECTION
The machine is provided with an automatic thermal protection system, which will stop the machine to prevent it from
overheating. When the Thermal Protection Indicator illuminates (fig. II-
), let the machine cool down.
MAINTENANCE
•
Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out maintenance work.
(DANGER High Voltage and Currents).
•
Maintenance should only be carried out by a qualified person.
•
GYS recommends removing the steel cover 2 or 3 times a year to remove any excess dust. Take this opportunity to
have the electrical connections checked by a qualified person with an insulated tool.
•
Regularly check the condition of the power supply cord. If damaged, it will need to be replaced by the
manufacturer, its’ after sales service or a qualified person.
SAFETY
Spot w elding can be dangerous and can cause serious and even fatal injuries.
Protect yourself and others. Ensure the follow ing safety precautions are taken:
Arc radiation
Protect yourself with a helmet fitted with filters in compliance with EN169 or EN
379.
Rain, steam, damp
Use your welding unit in a clean/dry environment (pollution factor ≤ 3), on a flat
surface, and more than one meter from the welding work-piece. Do not use in rain
or snow.
Burns
Wear protective (fire-proof) clothing (cotton, overalls or jeans).
Wear protective gloves and a fire-proof apron.
Ensure other people keep a safe distance from the work area and do not look
directly at the welding arc.
Protect others by installing fire-proof protection walls.
Fire risks
Remove all flammable products from the work area. Do not work in presence of
flammable gases.
Electric shocks
This device must only be used with an earthed power supply. Do not touch the
parts under tension. Check that the power supply is suitable for this unit.
Fumes
Do not inhale welding gases and fumes. Use the device in a well ventilated
environment, with artificial extraction if welding indoors.
Electromagnetic perturbations Near the spot welding, check that:
there is neither no other power supply cable nor control lines, nor phone cables,
nor radio or TV reception appliances, nor watches, nor mobile phones, nor
magnetic cards, nor computers or any other electronic appliance.
Falls
Do not move the unit over people or objects.
Additional precautions
Any welding operation undertaken in:
- rooms where there is an increased risk of electric shocks
- poorly ventilated rooms
- the presence of flammable or explosive material
should always be approved by a "responsible expert", and made in presence of
people trained to intervene in case of emergency.
Technical protection as described in the Technical Specification CEI/IEC 62081
must be implemented.
Welding in raised positions is forbidden, except in case of safety platforms use.
GYS cannot be held responsible for damage to persons or items, as a result of using the machine in the following
circumstances:
•
Modification or neutralisation of safety elements has been undertaken
•
Safety recommendations written in this manual have not been adhered to
•
Modification of the product’s specifications
•
Use of accessories not specified by the manufacturer
•
Failure to observe regulations specific to the country or state in which the machine is used.
