ADVICE & THERMAL PROTECTION
(POWERMIG GENERATOR 400W) NEVER USE YOUR UNIT WITHOUT COOLING LIQUID
when the pump is working.
Failure to adhere to this may result in irreparable damage to the cooling system, and machine
•
The PowerMig 400-4 should not be lifted by its handles, torch support, or the top of the machine. When lifting
the PowerMig,
ensure the weight is fully supported at the bottom of the machine
. There must be no
gas bottle connected during this operation.
•
Always respect the basic rules of welding.
•
Do not block/cover the ventilation holes of the machine.
•
Leave the device plugged in after welding to allow proper cooling down.
•
Thermal protection: If the machine becomes too hot, the warning light will illuminate and the machine will
stop. Cooling will take a few minutes, the length of time will also depend on the external temperature.
DUTY CYCLE & WELDING ENVIRONMENT IN USE
•
The welding unit describes an output characteristic of "constant current" type. The duty cycles following the
standard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table below:
X / 60974-1 @ 40°C (T cycle = 10 min)
I max
60% (T cycle = 10 min)
100% (T cycle = 10 min)
PowerMig 400-4 / PowerMig Twin 400-4 /
PowerMig Generator 400W
25% @ 370 A
280 A
210 A
Note: The machines’ duty cycle has been tested at room temperature (40°C) and has been determined
by simulation.
These are Class-A devices. They are designed to be used in an industrial or professional environment. In a
different environment, it can be difficult to ensure electromagnetic compatibility, due to conducted disturbances
as well as radiation.
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).
We recommend 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.
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).
