IGBT Inverter Full Bridge Welding Machine 220V/380V - Top China Suppliers & Factory For Durable Welding Solutions
Detailed Information
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:
• 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.
• 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.
