Precautions and maintenance of welding machine

1.Safety points

The welding machine is equipped with overcurrent and overheat protection circuits.
When the grid voltage, output current and internal temperature exceed the set standard,
the welding and cutting machine will automatically stop working, but excessive use
(such as excessive voltage) will still cause welding The machine is damaged, so you
still need to pay attention to the following:
Ensure good ventilation！
1
When the machine is in operation, there is a large working current passing through,
and natural ventilation cannot meet the cooling requirements of the welding machine, so
a fan is built in to effectively cool the welding machine to make it work smoothly. The
user should confirm that the ventilation place is not covered or blocked, and the distance
to the surrounding objects should not be less than 0.3 meters. The user should always
pay attention to maintain good ventilation, which is very important for the welding
machine to work better and ensure a longer life of.
No overload！
2
The user should pay attention to the use of the welding machine according to the
allowable load continuity rate (refer to the welding machine nameplate parameters) to
keep the welding current not exceeding the maximum allowable load current. Current
overload will significantly shorten the service life of the welding machine, and may
even burn the welding machine. Load continuity rate: the current welding time
corresponding to the load continuity rate, 10 minutes is a cycle, working time + rest time
= 10 minutes; for example, 30%, 200A / 28V, that is, output current 200A, it should
work for 3 minutes 7 minutes rest; 60%, 141A / 25.6V, output current 141A, should
work 6 minutes, rest 4 minutes.
Current overload will significantly shorten the service life of the welding machine,
