6. PRECAUTIONS

6.1 Surroundings
6.1.1 The welding operation should be carried out in a relatively dry environment, and the air
humidity should generally not exceed 90%.
6.1.2 The ambient temperature should be between -10C and 40C.
6.1.3 Avoid welding in daylight or rain, and do not allow water or rain to seep into the welder.
6.1.4 Avoid welding work in dusty areas or in corrosive atmospheres.Avoid gas-shielded welding
operations in environments with strong air flow.
6.2 Safety
6.2.1 Overvoltage, overcurrent and overheat protection circuits have been installed in our welding
machine. When the grid voltage, output current and internal temperature exceed the set standard,
the welder will automatically stop working; but excessive use (such as voltage over High) will still
cause damage to the welder, so you still need to pay attention to the following matters.
6.2.2 Ensure good ventilation.
Our welding machine is a small welding machine. When operating, there is a large working current,
and natural ventilation can not meet the cooling requirements of the welding machine. Therefore,
a fan is installed to effectively cool the welding machine to make it work smoothly.
The user should confirm that the ventilation is not covered or blocked, and the distance between
the welder and the surrounding objects should be no less than 0.3 meters. The user should
always pay attention to maintain good ventilation, which is better for the welder and guarantees a
longer service life. very important.
6.2.3 No current overload
The user should remember to observe the maximum allowable load current (relatively selectable
load continuation rate) and 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.
6.2.4 No too high voltage
The power supply voltage is listed in the "Main Performance Parameters" table. Under normal
circumstances, the voltage automatic compensation circuit in the welder will ensure that the
welding current is kept within the allowable range. If the power supply voltage exceeds the
allowable value, the welder will be damaged and the user should fully understand the situation
and take appropriate precautions.
6.2.5 A grounding screw is attached to the rear of each welder and marked with a grounding mark.
Before use, use a cable with a section larger than 6mm2 to reliably ground the welder's casing to
discharge static electricity or prevent accidents due to electric leakage.
6.2.6 If the welder exceeds the standard load continuation rate during operation, the welder may
suddenly enter the protection state and stop working. This means that the welder exceeds the
standard load continuation rate. Excessive heat energy triggers the temperature control switch,
causing the welder to stop working while being in front. The the digital display shows -E2. In this
