Welding Machine Precautions And Maintenance - ANDELI TIG Series Instruction 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
 Forbidden voltage too high!
The power supply voltage is listed in the "main performance parameters" table. In general,
the automatic voltage compensation circuit in the welding machine will ensure that the welding
current remains within the allowable range. If the power supply voltage exceeds the allowable
value, it will damage the welder. The user should fully understand this situation and take
corresponding preventive measures。
