Page 3: Safety Notices
Safety notices For the sake of your and other's safety, please read the manual carefully before installation or operation of the equipment! The people operating the equipment or nearby should fully know about safety measures. The safety will be fulfilled through everyone's common effort. - Page 4 1. Main purposes and features 1.1 Main purposes IGBT inverter gas-shielded welders of GMAW/MIG series include Model 200, 300, and 400. They are mainly applicable to CO2-shielded welding, consumable electrode argon arc-welding (GMAW/MIG), and mixed gas- shielded welding (GMAW/MAG). They conform to safety requirements...

6. Function description Function description of the front/rear panel of the arc-welding rectifier Name Description Amperemeter Preset and display the output current of the welder Voltmeter Preset and display the output voltage of the welder Power indicator light Indicate if the power supply of the welder is turned on/off. - Page 9 7. Use and operation 7.1 Preparation before use Connect the input power cable of the welder to the power grid according to the requirements. (Refer to 5. Installation and attention) Attention: The three relatively thick wires are connected respectively to the phase wire of the three-phase power supply.
- Page 10 Attention: If the "Wire-selection" switch is put to a incorrect position, the welding current will not match with the preset value. The "Function" switch position is incorrect. When the contact tip is burned or in a poor contact, it is necessary to replace it to avoid affecting the welding stability.
- Page 11 8. Maintenance and troubleshooting 8.1 Maintenance After the arc-welding rectifier is used for a period of time, it is necessary to remove dust and dirt in the equipment with the dry compressed air or in other way to ensure the arc-welding rectifier functions properly for a long time, and prolong its service life.
