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。
It is forbidden to use the welding machine for thawing pipes。
The back of each welding machine is attached with a ground screw, and
marked with a ground mark. Before use, select a cable with a section greater
than 2.5mm2 and ground the welding machine shell reliably to release static
electricity or prevent accidents that may occur due to electricity leakage.
If the welding machine exceeds the standard load duration, the welding
machine may suddenly enter the protection state and stop working, which
means that the welding machine exceeds the standard load duration. If the
temperature is too high, the temperature control switch will be triggered and the
welding machine will stop working. Meanwhile, the yellow indicator light on the
front panel will be on. In this case, you do not need to unplug the power supply
so that the cooling fan can continue working to cool the welder. When the
yellow indicator light is off, the temperature drops to the standard range and the
welding can be resumed.
2. Maintenance
Warning
：
！
All maintenance, service and cleaning work must be performed with power
removed. Make sure you have unplugged the power cord before
opening the casing.
Dedust regularly. Use dry, clean compressed air to clean up the system.
Dedust every day when operating in smoky conditions or severely polluted air.
The compressed air should be delivered at the required pressure to avoid the
