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
