Features

1. Smart boot

When the welding machine is turned on, the impact on the power grid is small

Automatic detection of input current and voltage, output voltage, it is true smart soft start

2. Force control

In the welding process, it can effectively improve the current penetration and make the penetration deeper

3. Better efficiency

Full load welding in 25℃ environment can achieve 100% duty cycle

Effectively improve work efficiency

4. Hot start control

Especially suitable for low-carbon steel J422, alkaline (J427, J506, J507, etc.) electrodes that are easy to arc

5. 32-bit microcontroller

Program calculation ability is better

The whole machine is more stable

6. Comes with anti-sticking control

Adopt a new generation of anti-sticking technology to efficiently solve the problems of arc welding rod sticking to the workpiece

7. Pulse manual welding

Welding spatter is obviously smaller than ordinary ARC welding, and the quality of welding seam is obviously improved

8. Electric welding technology application breakthrough, manual pulse technology

Pulsed arc automatically and rhythmically push the electrode forward

Unused welders also can weld fish-scale welds

9. Extraordinary design

Strongly replace the traditional inverter DC ARC welding machine

120% duty cycle can be achieved for full load welding in a 30℃ environment

100% duty cycle can be achieved for full load welding in a 40℃ environment

10. Multi-core check protection

When the machine encounters a fault, it will automatically protect the machine and display the fault code

11. Lifting TIG welding

Arc starting does not stick to the workpiece

Effectively reduce the loss of tungsten needles

The arc starting success rate is over 99%

12. Available generators

The whole series of products can work arbitrarily between 160V-560V, without fear of any high voltage

13. Adopt IGBT dual module

The quality is more reliable and stable

14. Multi-core check protection

When the machine encounters a fault, it will automatically protect the machine and display the fault code

Screen display code Code reminder Cause of problem
r01 overheated Dust removal and inspection of fan
r02 Overpressure Check input voltage
r03 Double pressure anomaly Check the input voltage and try to turn it on and off again
r04 No load abnormality Check the output signal line or MUR and transformer
r05 Undervoltage Check input voltage
r06 Abnormal temperature control Or check the harness
r07 Hall anomaly Or check the harness
r08 internal fault Please contact dealer
