5.1.2 Operation
1. After the correct installation per above methods, please turn on the power switch (“ON”).While the power supply is “ON”,
welder starts to work normally with indicator lighting up and fan working.
2.
Please pay attention to the polarity while connecting. There are normally two ways of wiring: DCEP and DCNP.
DCNP: welding holder connected to “-“and work piece to “+”.
DCEP: workpiece to “-“and welding holder to “+”.
Please choose the proper connection method according to different workpiece and processing methods. Unstable arc,
spatter, and electrode sticking could happen if improper polarity is selected. Please change the quick connect plug to
change the polarity in case of above abnormal situation.
3. When switching the welding mode to MMA, welding can be carried out with output current in rated range.
4. Select guide line with larger cross-section to reduce the voltage drop if the welder and workpiece distance is too far and
secondary cables (welding cable and earth cable) are long.
5. Preset the welding current according to electrode type and size. Clamp the electrode and then welding can be carried out
by short circuit arc ignition.
For welding parameters, please refer to the table on the following page.
5.1.1 Installation
1. Connect the primary power line to the according voltage class. Please make sure the power line is connected to the right
voltage class.
2.
Make sure the primary source is in fine contact with the according power line terminal or socket and prevent oxidation.
3.
Measure the voltage with multi-meter and check if it’s in the fluctuation range.
4. Insert the earth clamp cable plug into the front panel’s below po” socket, and screw tightly clockwise.
5. Insert the electrode holder cable plug into the front panel’s upper position”-“socket and screw tightly clockwise.
6. Make sure the supply is in good earthing condition.
