Noise produced during welding can easily cause hearing loss ◆ In order to avoid the harm of noise to you and others, please wear the prescribed protective equipment. Matters needing attention in hoisting ◆ The power source with strap or hand is prohibited from using strap or hand for lifting.
2 Overview Product Introduction The welding machine applies the most advanced inversion technology in the world. The principle of inversion is to transform the power frequency of 50Hz/60Hz into direct current and invert it into high frequency through high-power device, then perform voltage-drop and commutation with the output high-power D.C power supply via Pulse Width Modulation (PWM).
3 Installation Install the Output Cable The machine is flux-cored welding. The torch and earth clamp are already fixed well in the machine. The welding equipment is equipped with power voltage compensation device. It keeps the machine work normally when power voltage fluctuating ±15% of rated voltage. When using long cable, in order to reduce voltage drop, big section cable is suggested.
4 Operating Functions Control Panel and label The panel components are described in the following table. Icons Name Description Used to adjust welding current. The power source is synergic designed, After the current is configured, the machine automatically matches the Adjusting Knob feeding speed.
Input/Output Panel Output Terminals Name Negative output terminal Positive output terminal Input Cable The I determines the input cable, correct plug and input current required for each 1eff machine. Max. effective supply current (I ) Input cable size 1eff ≤10 A 1.5-2.5 mm 1eff ≤16 A...
5 Operation Instructions of Operation Steps Steps Description After connecting the power supply, the machine is in standby state when 1 Connect the power the pointer points to “stand-by”, and the power indicator lights on when supply the pointer is adjusted to 1 or more. The welding machine is installed with internal wire feeder.
6 Environment and Problems Environment Note: The power source should not be used in rain or snow environment. The recommended external environment for welding is as follows: ◼ Please place the power source in a horizontal position. The inclination of the power source shall not exceed 10°.
Problems During Welding Fittings, welding materials, environment factor, supply powers maybe have something to do with welding. User must try to improve welding environment. Problems Solutions 1. Examine whether grounding wire clamp contacts with the work pieces well. Arc starting is difficult and easy to break.
7 Daily Maintenance and Checking Daily Maintenance In maintenance of the unit, take into consideration the rate of use and the environment it is used in. When the unit is used properly and serviced regularly you will avoid unnecessary disturbances in use and production. ◼...

8 Trouble Shooting IMPORTANT: Only authorised repair agents with valid certifications should carry out repairs and internal servicing. Fault symptom Remedy 1. Make sure the power cord is connected. 2. Check if electric wire net is in work. 3. Some of heat-variable resistors(four) of power panel is damaged, when it happen, general DC14V relay is open or connectors are poor contact.

Fault symptom Remedy again: 1) If abnormal indicator is still lit, some of fieldistor of IGBT board are damaged, find out and replace them with same model. 2) If abnormal indicator is not lit: a. Maybe transformer of middle board is damaged, measure inductance volume and Q volume of main transformer by inductance bridge.
