Product overview

The principle of gas shielded arc welding in our company is to convert the 50 Hz commercial power into DC power first, and then convert the DC power into high-frequency AC power by using high-power switching device IGBT, and then reduce the voltage for rectification. With unified adjustment, no need to match the voltage and wire feeding speed, easy operation, so as to achieve the best welding effect. Among them, the dual-function model has self-protection welding wire, 0.8 welding wire and 1.0 welding wire, switching welding mode, and manual welding function. Various welding modes and processes can be adjusted freely according to user’s habits.
The features of this machine are as follows:
GBT inverter technology, current mode control, reliable quality, stable performance.
Closed loop feedback, constant output, strong anti network voltage fluctuation ability.
Electronic reactor control, stable welding process, small spatter, deep molten pool and good forming.
It is easy to start arc and cut the ball after welding to ensure the welding quality. It has the function of unified adjustment and is more convenient to operate.
Compared with the traditional welding machine, the single chip microcomputer control technology greatly reduces the number of components and improves the reliability of the circuit The efficiency of this machine can reach 85%, which is 30% less than that of traditional welding machine.

Matters need attention

1. Environment
   

2. The welding operation shall be carried out in a relatively dry environment. and the air humidity shall generally not exceed 90%.

3. The ambient temperature should be between -10°C and 40°C.

4.  Avoid welding in sunligh t again, and don’t let parallel rainwater seep into the welding machine. Avoid welding in dusty areas or environments containing corrosive gases.

5. Safety essentials Protection circuit has been installed in our welding machine. When the set standard is exceeded. the welding machine will automatically stop working; But excessive use (such as voltage Too high) will still cause damage to the welding  machine, so you still need to pay attention to the following matters:

6. ensure good ventilation! When the welding machine is working, there is a large working current, and natural ventilation cannot meet the cooling requirements of the welding machine, so a fan is installed inside to effectively cool the welding machine and make it work smoothly. Users should confirm that the ventilated place is not covered or blocked, the distance between the welder and surrounding objects should be no less than 0.3m, and users should pay attention to keep good ventilation all the time, which is very important for the welder to work better and ensure a longer service life.

7. Overload is prohibited! Users should remember to observe the maximum allowable load current (relative to the selectable load duration rate) at any time, and keep the welding current not exceeding the maximum allowable load current. Current overload will obviously shorten the service life of welding machine, and may even burn the welding machine.

8. It is prohibited that the voltage is too high! The power supply voltage is listed in the “main performance parameters” table. Under normal circumstances, the automatic voltage compensation circuit in the welding machine will ensure the welding current to be maintained Within the allowable range. If the power supply voltage exceeds the allowable value, the welding machine will be damaged, and the user should fully understand this situation and take corresponding measures Preventive measures.

9. A grounding screw is attached to the back of each welder and marked with a grounding mark. Before use, select a cable with a cross section greater than 6mm2. Ground the welding machine shell reliably to release static electricity or prevent accidents that may occur due to electric leakage.

10. If the welding machine exceeds the standard load continuous rate when working, the welding machine may suddenly enter the protection state and stop working, which means that the welding machine exceeds the standard Load duration, excessive heat energy triggered the temperature control switch, so that the welder stopped working and the yellow light came on. In this case, you don’t have to unplug it Source plug, so that the cooling fan can work continuously to cool the welder. When the temperature drops to the standard range and the yellow light goes out. welding can be restarted.
