Welding Machine Precautions And Maintenance - ANDELI MIG-270E User Manual

Welding machine precautions and maintenance

1. Safety points
The welding machine is quipped with overcurrent and overheat protection
circuits.When the gird voltage,output current and internal temperature exceed the
set standard the welding machine will automatically stop working,but excessive
use(such as excessive voltage) will still lead to welding,The machine is
damaged,so you still need to pay attention to the following:
 Make sure the ventilation is good！
When the machine is in operation,a large working current passes,natural
ventilation can not meet the cooling requirements of the welder,so a fan is installed
to effectively cool the welder to make it work smoothly.The user should confirm that
the ventilation area is not covered or blocked,and the distance from the
surrounding objects should be no less than 0.3 meters.Users should always pay
attention to maintain good ventilation.which is very important for better working of
the welding machine and guaranteeing longer service life of.
 It is forbidden to overload！
The user should pay attention to the use of the welder according to the
allowable load duration of the welder(refer to the welder nameplate parameters) to
keep the welding current not exceeding the maximum allowable load current
Current overload will significantly shorten the life of the welder and may even burn
the welder.Load continuation rate:that is the current welding time under the load
continuation rate,10 minutes is a cycle,working time+rest time=10 minutes;For
example,30%,200 A/28 V,that is the output current 200 A state,should work for 3
minutes.Rest for 7 minutes;60%,141 A/25.6 V,in the state of output current 141
A,should work for 5 minutes,rest for 4 minutes.
Current overload will significantly shorten the life of the welder
