Welding Machine Instructions:

4.1 After the welding machine is plugged into the power supply, the equipment is in a dormant standby state, and there is no display on the screen. At this time, press and hold the multi-function knob on the welding machine (press and hold for 1 second), and the device screen displays the boot screen and enters the power-on self-test process.
After the self-test is passed, the screen displays the interface as shown in Figure (1), and the welding machine enters the working state at the same time and the cooling fan inside the unit should start working immediately. In the working state, press and hold the multi-function knob again (press and hold for 3 seconds) the device shuts down and the screen turns off, the welding machine enter the standby hibernation state.

4.2 Select the multi-function knob to determine the appropriate welding current according to the thickness of the welding workpiece, the diameter of the electrode, the station and the process needs.
4.3 In the working state of the welding machine, through the multi- function knob, the welding machine enters the parameter setting page as shown in figure (2). In this page, the user can understand the functions of the welding machine and how to use it.

4.4 The machine is equipped with a prevent electric shock device, set the VRD option to “ON” in the parameter setting inter face. At this time, the VRD function is turned on; When the VRD option is in the “OFF” position, the VRD function is turned off, and the no-load voltage is 75V. If the machine has the VRD function, and the VRD option is always in “ON” state, the no-load voltage is lower than 18V, the output terminal will not cause harm to the human body.

4.5 Environmental requirement:

1. The welding operation should be carried out in a relatively dry environment, and the air humidity should generally not exceed 90%.
2. Ambient temperature should be -10°C between 40°C.
3. Avoid welding in sunlight or rain, and do not let water or rain seep into the welding machine
4. Avoid welding in dusty areas or environments containing corrosive gases

Start-up troubleshooting

The power-on system will automatically detect the grid voltage, and the machine is normal. If there are abnormal factors in the machine, the computer system will detect and jump out of the fault code. The display is as follows

1. If the voltage is abnormal when the power is turned on, press and hold the power button to restart (you can also unplug the power plug, etc. after the interface is black, plug it in and press the power button to start)
2. If it is in use, the interface displays: self-check over current. On behalf of the machine welding positive and negative short-circuit protection, the positive and negative poles are separated, restart and use normally
3. If an abnormal temperature appears on the interface during use, it means that the internal components of the machine have reached the highest temperature protection value. There is no need to shut down and wait for about forty seconds.
   Forced air intake by the fan will reduce the temperature of the internal components. Can be welded normally

6.1 Hot start
Click the function knob interface to display arcing Click the knob again and turn it clockwise
Increase the arc current. Set the appropriate arcing current and click the knob again to exit the arcing function, and turn clockwise to the next function
Arc starting: The current can increase the short-circuit current value, make the welding rod difficult to bond with the workpiece, facilitate the smooth transfer of the droplet, and facilitate the welding. Hot arc ignition current can increase the success rate of arc ignition and increase the short-circuit current at the moment of short circuit to facilitate arc ignition.
Electric welding machine uses electric energy to convert electric energy into heat energy instantly. Electricity is very common. Electric welding machine is suitable for working in a dry environment. It does not require much. Because of its small size, simple operation, convenient use, and faster speed, it is welded after welding. The advantages of strong seam are widely used in various fields;
It is especially practical for parts that require high strength. It can instantly connect the same metal material (also can connect dissimilar metals, but the welding method is different) permanently. After heat treatment, the weld seam will have the same strength as the base metal and be sealed. Very good, this solves the problems of sealing and strength for the manufacture of storage gas and liquid containers.

• For the first use, it is recommended to set the current at 5%, and then adjust the current according to the depth of the welding groove of the workpiece
