Detailed Information
Safety Warning & Protection
Electrical connection must be carried out after turning off the power switch of the distribution box! The protection level of the welder is IP21S, which shall not be used in the rain without cover! It is forbidden to use the welding power source for pipe thawing!
To ensure personal safety and avoid electric shock accidents, please connect the earth wire (yellow and green wires) to the distribution box earthing device reliably. The cross-sectional area of the conductors for the distribution box shall meet the requirements of maximum input capacity.
Insert the cable plug of the welding clamp and the cable plug of the earth clamp into the quick outlet on the front panel of the welder respectively and screw them clockwise. Operators can also choose the DC positive connection method according to the base metal and the electrode. In general, DC reverse connection (i.e., connecting the electrode to the negative pole) is recommended for basic electrode, whereas for acid electrode, there is no particular requirement.
Output Line Connection Methods
- DC positive connection method: welding clamp to negative pole and workpiece to positive pole
- DC reverse connection method: welding clamp to positive pole and workpiece to negative pole
Routine inspection is vital for the high use performance and safe operation of the welder. The routine inspection shall be conducted according to items in the table below, and cleaning or replacement shall be conducted if necessary. For the purpose of ensuring the high performance of the welder, the components provided or recommended by our company shall be used for the replacement of components.

Frequently Asked Questions
Can this welding machine be used in the rain?
No. The welder has an IP21S protection level and must not be used in the rain without a protective cover. Always ensure the machine is kept dry.
What connection method is recommended for basic electrodes?
For basic electrodes, the DC reverse connection method is generally recommended, where the welding clamp is connected to the positive pole and the workpiece to the negative pole.
How does the 220V-380V power grid identification technology work?
The machine utilizes mature IGBT full-bridge inverter technology to automatically identify input network voltages between 220V and 380V, automatically converting the output current to match.
Can I use this welder with a generator?
Yes, this welding machine is compatible with generators and is designed to support welding operations with cables up to 100 meters long.
What are the key safety requirements for installation?
Ensure the power switch is off before making electrical connections. The earth wire must be reliably connected to the distribution box. The input cable should be 4mm² (length ≤ 3m) and the output cable should be 16-25mm² to handle the capacity safely.
