GYS TIG 250 AC/DC, Руководство пользователя

Страница: 16 / 24

The integrated cooling unit is designed to detect if a water cooled torch is connected or not. Please do
not short-circuit the cooling unit. If you do so, the machine will not be able to work to its full
specifications.
DUTY CYCLE
•
The machine has a specification with a “constant current output”. The duty cycles according to the normal
EN60974-1 (@ 40°C during 10min) are indicated in the following table:

MAINTENANCE/ ADVICE

Maintenance should only be carried out by a qualified person.

Ensure the machine is unplugged, and that the ventilator inside has stopped before carrying out maintenance
work. (DANGER High Voltage and Currents).

JBDC 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 cable. If damaged, it will need to be replaced by the
manufacturer, its’ after sales service or a qualified person.

Ensure the ventilation holes of the device are not blocked to allow adequate air circulation.

Before each use, check the state of welding cables of the torch and earth clamp (The conductive metal should not
be exposed).
SAFETY
Arc 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.
Electric shock This device must only be used with an earthed power supply. Do not touch the parts
under high voltage. Check that the power supply is suitable for this unit.
Falls
Do not place/carry the unit over people or objects.
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 curtains.
Fire risks Remove all flammable products from the work area. Do not work in presence of
flammable gases.
Fumes Do not inhale welding gases and fumes. Use the device in a well ventilated environment,
with artificial extraction if welding indoors.
Additional Any welding operation undertaken in.....
Precautions
- rooms where there is an increased risk of electric shocks,
- Poorly ventilated rooms,
- In the presence of flammable or explosive material,
Use 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 should not be undertaken, except in case of
safety platforms use.
