THERMAL PROTECTION & DUTY CYCLE
•
Thermal protection : thermal protection indicator turns on and the cooling time is about 2 to 5 min according to
external temperature.
•
Leave the machine connected to the supply after welding in order to let it cool down.
•
The welding unit describes an output characteristic of "constant current" type. The duty cycles following the norm
EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below :
Note : the overheating tests have been made at room temperature and the duty cycles at 40°C have been
determined by simulation.
MAINTENANCE
•
Refer all servicing to qualified personnel.
•
Disconnect the generator and wait until the ventilator stopped before working on the unit. Inside the device,
voltages and current are dangerous.
•
Regularly remove the steel cover and blow off the dust with compressed air. Let check the electrical connections
(with an insulated tool) and the insulations by qualified personnel.
•
Regularly control the state of the cord. If this supply cable is damaged, it must be replaced by the manufacturer,
its after sales service or a similarly qualified technician to avoid any danger.
ADVICE
•
Respect welding polarities and currents indicated on the electrode packaging
•
Remove the electrode from the electrode holder when you do not use it.
•
Leave the inlets free to allow in/out air circulation.
SECURITY
The arc w elding can be dangerous and leads serious injury, may fatal. Protect yourself and protect the
others.
Respect the following warnings:
Arc rays :
Protect yourself thanks to a welding helmet in compliance with EN175 equiped with filters
in compliance with EN 169 or EN 379. Inform and protect by the same means any people
in the welding environment.
Rain, steam,
The working environment must be clean (degree of pollution ≤ 3) and protected
humidity :
against rain. Put the appliance on an even place and at least at one meter from the parts
to be welded. Do not use them under rain or snow.
Electric shocks :
The INVERTER 4000 must not be used on a single phase power outlet with 3-wire
grounded neutral. Do not touch live parts. Check that the supply system is suitable for the
post.
Moving :
Do not underestimate the weight of the apparatus. Do not carry it over people or things.
Do not drop it. Do not set it brutally
Burns :
Wear protective or fire-proof clothing (overalls, jeans).
Use some welder gloves and a fire-proof apron.
Protect the others by installing non flammable protection wall , or prevent the
others to not look at the arc and to keep a sufficient distance
