1. Environment
(1)
The welding operation shall be operated in a relatively dry environment, and the
air humidity should not exceed 90 percent.
(2) The ambient temperature should be between -10 and 40 .
(3) Do not weld under the sunlight or in the rain, and do not let water or rain go
into welding machine.
(4) Do not weld in dust or under the environment containing corrosive gases.
(5) Do not weld at the vibrant and easy-collision places.
2. Security key points
The welding machine has been installed protection circuit against over current
and overheat, which will automatically stop working when the temperature is higher
than the standard and welding machine will enter the state of protection when the flow
is excessive. But excessive use (such as welding current excessive) would have still
caused damage to the welding machine, so you need to pay attention to the
followings:
(1) To keep good ventilation!
Since the size of the welding machine is small, natural ventilation can not meet
the need of cooling it when strong current goes through it, we use a cooling fan to
make it work smoothly.
User should confirm the ventilation is not covered or blocked. The distance
between the machine and the surrounding objects must be kept no less than 0.3
meters. The user should always keep it good ventilation, which is very important to
work efficiency and service life of the machine.
(2) To prohibit electric current from overloading!
User Should observe the strongest load current (relatively to the selected load
sustained rate) at any time,so as to ensure the welding current against exceeding the
allowed maximum.
The life expectancy of welding machine will be significantly shorten,or even be
burned, by overload current.
(3) To prohibit over voltage!
The power voltage is listed in the main technique parameters such as these in
form1, in normal conditions; the voltage auto-compensation circuit in the welder limits
the welding current within normal range. If the power voltage exceeds the normal
range, the welding machine will be damaged. As a result, the operator should be fully
aware of the situation and proper protective measures should be taken.
